Garmin Rally vs Wahoo POWRLINK vs Favero Assioma vs SRM X-Power

It’s been about 5 years since I’ve final performed an influence meter pedal comparability submit. Primarily, as a result of not a lot had modified in 5 years. The Favero Assioma will likely be 5 years outdated this summer season (loopy, huh?), and whereas the Garmin Rally pedals will likely be 1 12 months outdated in a couple of weeks, these spindles are principally simply the Vector 3 spindles with new pedal our bodies. Additional, after the SRAM acquisition, they killed off gross sales of the PowerTap pedal lineup. Nevertheless, final month Wahoo began delivery their long-awaited Wahoo POWRLINK Speedplay-based energy meter pedals.

So, combining the newishness of the Garmin Rally, with the brand new Wahoo pedals, and the SRM X-Energy SPD pedals of early final 12 months, it was time to mud the covers off this submit idea and spin out a brand new model up to date for 2022. Heck, at this price you would possibly even get an entire annual energy meter purchaser’s information too!

Now, I’ll in all probability provide the spoiler upfront: By and huge, all of those pedals lined . are stable. And realistically, the most important deciding issue for most individuals will likely be both cleat kind or worth. Positive, t. are particulars past that – however for most individuals, they aren’t deciders. I take advantage of all of those pedals in my testing of different trainers and energy meters. So I do belief all of them at this level. One thing I can’t say for all energy meters (and even all pedal-based energy meters).

With that, let’s dive into it.

Cleats & Pricing:

First up, is the cleat sorts of every. That is undoubtedly the largest decider for most individuals, adopted intently by worth.

Garmin Rally Collection: SPD (Rally XC), SPD-SL (Rally RS), and Look KEO (Rally RK)
Favero Assioma: Look KEO Variant, SPD-SL
SRM X-Energy: SPD, Flat Pedals
Wahoo POWRLINK: Speedplay

All 4 firms embrace inventory cleats within the field for his or her respective pedals.

You’ll discover I say ‘LOOK KEO Variant’ for the Favero Assioma pedals. Just like the now discontinued PowerTap P1/P2 pedals, the Favero pedals don’t technically use LOOK Keo cleats. They use an off-brand variant, which could be very barely totally different. Since Favero consists of the cleats within the field, it’s not a giant deal in the event you’re solely utilizing these pedals together with your biking sneakers. Nevertheless, if in case you have different Look KEO pedals, then you definately’ll see some slight distinction. After years of utilizing them, I discover that I can seamlessly use my biking sneakers between legit Look KEO pedals and Favero Assioma pedals with both cleat kind, so long as they’ve obtained a couple of days of use on them. That appears to interrupt them in sufficient that they work simply high-quality.

In relation to pricing, . are the official costs of all of them for dual-sided items:

Garmin Rally Collection: $1,099 for Rally SPD-SL, $1,099 for Rally Look KEO, $1,199 for Rally SPD
Favero Assioma: $719 ($589 for DUO-Shi model spindles)
SRM X-Energy: $1,299
Wahoo POWRLINK: $999

Word that for the Favero Assioma DUO-Shi items, which is their SPD-SL variant, it’s a bit funky. They don’t promote you the pedals within the field. As a substitute, they promote you the spindles, and you need to do a quick arts and crafts mission to place the 2 items collectively.

As well as, additionally they supply single-sided items, which implies they solely stick electronics in a single facet, and the opposite facet is a dummy pedal with out electronics. In all circumstances, they offer you two pedals, however once more, solely one in all them has electronics. All firms supply an improve path to a dual-sided unit, although that often prices extra (and at the moment, Wahoo hasn’t finalized pricing of that improve path, set for later this 12 months).

Garmin Rally Collection: $649 for Rally SPD-SL, $649 for Rally Look KEO, $699 for Rally SPD
Favero Assioma: $459
SRM X-Energy: $999
Wahoo POWRLINK: $649

The largest distinction or advantage of the Rally system on this cleat-realm is you could transfer your spindle from one Rally pedal kind to a different. So in the event you do highway biking in the summertime on SPD-SL or Look KEO, however then swap to mountain biking or gravel for the autumn/winter, you possibly can merely transfer the spindles between pedal our bodies (and that’s completely suitable with Vector 3 spindles too). I’ve a complete video . on do it, it’s fairly straightforward.

Word that Favero does have two totally different spindles between their Assioma and Assioma Duo-SHI, and you’ll’t swap between them. You possibly can nevertheless take issues into your individual fingers although and convert the bottom Favero Assioma pedals from LOOK KEO to SPD (MTB), however you’ll wish to remember that doing so not solely voids your guarantee but additionally might require you trim the sides of your biking sneakers too. GPLAMA has a information for the way to take action ..

Sizing & Weights:

First up, we’ve obtained the weights of the pedals. Up till the Wahoo pedals, this was really a comparatively easy comparability. Nevertheless, one of many caveats of the Speedplay platform (no matter energy meters), is that it shifts a good chunk of weight from the pedal to the cleat. In fact, this together with Wahoo’s elimination of sure vowels makes the pedal lighter, however doesn’t make the entire system lighter, because you, in fact, require the cleat for the pedal to work.

So, beginning off with the weights of the pedals (proven individually), first up the Garmin row:

DSC_9524 DSC_9522 DSC_9523

Then the SRM, Wahoo, and Favero pedals:

DSC_9527 DSC_9525 DSC_9526

Word that for all of these, I excluded spacers, as not each crankset would require that. A single spacer is mostly 1g (you’ll doubtless use one spacer per facet):


Subsequent, a full comparability of the weights concerned (complete system weight is proven for the entire worth):

Favero Assioma LOOK-KEO system: 382g = 152g per pedal + 39g in mounting per facet
Garmin Rally Look KEO system: 404g = 165g per pedal plus 37g in mounting per facet
Garmin Rally Shimano SPD-SL system: 398g = 159g per pedal + 40g in mounting per facet
Garmin Rally Shimano SPD system: 512g = 221g per pedal + 35g in mounting per facet
SRM X-Energy SPD system: 396g = 172g per pedal + 26g in mounting per facet
Wahoo POWRLINK ZERO Speedplay system: 432g = 138g per pedal + ~78g mounting (cleats/baseplate/screws)

Now, .’s how the pedals look from the entrance. On the primary set it’s (left to proper) Garmin Look KEO, Garmin SPD-SL, Favero Assioma Duo. And the second set is SRM X-Energy, Garmin SPD, and Wahoo POWRLINK Zero.

DSC_9535 DSC_9536

Then from the spindle-side:

DSC_9538 DSC_9537

Then the opposite facet:

DSC_9539 DSC_9540

And eventually, the rear:

DSC_9541 DSC_9542

Clearly, the Speedplay seems the thinnest ., however once more, keep in mind that it’s a weight and bulk switch equation. You’re merely shifting that weight and bulk to the shoe from the pedal. I cowl issues like stack heights a bit afterward down.

Set up:


The set up of those items is all principally foolish straightforward and fast. All items use both customary pedal wrenches, or customary 8mm hex wrenches to put in, relying on whether or not or not t. are electronics within the spindle. Realistically, this isn’t a lot totally different than different pedals, which differ on whether or not to make use of a pedal wrench or a hex wrench inserted into the spindle. Additionally, typically, I don’t use the thinner 15mm wrench proven above, however I don’t know why all three of my regular pedal wrenches aren’t w. they’re presupposed to be right now.

Garmin Rally Collection: Pedal wrench
Favero Assioma: Hex wrench
SRM X-Energy: Pedal wrench
Wahoo POWRLINK: Hex wrench

For all of those, you’ll go forward and tighten fairly snugly. The precise torque quantity varies barely, however as a basic rule of thumb for energy meters, you don’t wish to be loosey-goosey on any of them. Equally although, you don’t wish to do loopy overtightening both, which may injury the threads. Plus, pedals do self-tighten routinely as you pedal, so in a worst-case situation, it’ll tighten up after your first journey.

For all pedals, I’d suggest doing 2-4 arduous sprints (I choose doing them on a coach when putting in any set of latest pedals), which ensures the pedals are good and cushty. Then do the calibrations as required.

With most pedals, they should decide their exact place. Garmin, Favero, and Wahoo all handle to do that internally with software program detection, SRM does require you utilize the app on first set up to specify the precise place. Nonetheless, this can be a 2-second factor whilst you’re setting the crank size, so it’s hardly a burden. It’ll take you extra time to do the required registration/activation on the Favero pedals, than it’s going to to do the crank angle on the SRM pedals.

Lastly, do be certain that your crank size is ready appropriately on any pedal-based energy meter. As a result of the crank size is used as a part of the ability calculation, in case your crank size is wrong, your energy output will likely be barely incorrect (roughly talking if in case you have 175mm cranks and don’t change it from the default 172.5mm, it’ll be about 1.8% off at 90RPM – with that hole growing the bigger the distinction). Once more, all of those apps ask to your crank lengths, and all bike computer systems will ask for it as effectively. However positive it’s set to the identical in each locations.

Elements and Stacks:

Within the IT trade one says ‘rack and stack’, however that didn’t actually make sense for the title ., as a result of t. are not any racks.  Simply Q-Elements, Stack Heights, and different measurement-focused issues.  I believe this class – greater than another – is filled with specs that individuals assume they care about, however don’t really care about in the true world.  We’ll begin with the prime instance of that, Q-Issue.


Q-Issue refers back to the distance between the centerline of the pedal and the tip of the threaded portion.  Beneath, is an instance of the Q-Issue from Favero, and for a single facet.  Typically occasions that is additionally represented on a motorbike as the space between the threads on the crank arms (each side) – akin to on an indoor bike. Technically that is really the stance width, however hey, let’s not try to repair the web in sooner or later.


Lots of people get actually bent off form about Q-Issue, however then neglect that the totally different bikes they’ve of their storage for various facets of biking all doubtless have totally different Q-Elements/stance widths.  For instance, a highway bike has a Q-Issue typically of ~150mm, whereas a mountain bike has a Q-Issue of 170mm.  Bounce on that WattBike?  It’s obtained a Q-Issue of 173 however the Atom is 160.  However wait, your gymnasium spin bike has a unique Q-Issue, and that’ll differ by manufacturers and fashions too.  Schwinn’s AC Efficiency is 170mm, whereas Keiser’s M3 is 197mm.

To not point out that the handful of research which have checked out Q-Issue principally all mentioned that t.’s a slight brief time period affect to switching distance of Q-Issue, however then like the rest your physique adapts.  That’s no totally different than another bike element.


Nonetheless, t. could also be particular medical the explanation why you wish to maintain issues related.  Thus, .’s w. you stand on Q-Issue:

Garmin Vector 3/Rally Collection: 53mm (55mm with their inventory spacer)
Favero Assioma: 54mm (55mm with their inventory spacer)
Favero Assioma Shimano SPD-SL: 65mm (for reference, a inventory Ultegra SPD-SL is 53mm)
SRM X Energy: 54mm
Wahoo POWRLINK ZERO: 55mm (a inventory Speedplay Zero is 53mm, but additionally provided in 56/59/65mm)

Once more, take into account that the Q-Issue will change by as much as 1-2mm relying on whether or not or not you utilize spacers, which in flip will depend on your particular crank arms. Usually talking, most energy meter pedals will in all probability require a single 1mm spacer, relying on crank sorts. I often use one for security, merely as a result of most crank arm sorts are skinny sufficient that when the pedal is tightened on, the pedal physique portion is usually barely wider, and might overlap onto the crank-arm away from the thread-hole space, which is unhealthy for each the pedals, crank arm, and accuracy. Additionally, you’ll use a spacer in case your chain clearance on the opposite finish is just too tight.

Stack Top:

Talking of stack peak, that is the measurement of the middle of the spindle to the underside of the shoe.  That is really a very powerful one to measure myself, as a result of slight ups and downs of the pedal.  So as an alternative I reached out to all the businesses to get the official stack peak numbers.  They’re as follows:

Garmin Rally RS (Shimano SPD-SL): 12.2mm
Garmin Rally XC (Shimano SPD): 13.5mm
Garmin Rally RK (LOOK KEO): 12.2mm
Favero Assioma (LOOK KEO): 10.5mm
SRM X-POWER: 10.5mm
Wahoo POWRLINK: 13mm

Some folks equate stack peak to the flexibility to nook, however that’s really not totally true. It’s a mix of each the stack peak and in impact the Q-Issue, since an extended spindle is basically the principle concern, as that’s the primary portion to hit.


Only a fast notice that float is definitely decided by the cleats you utilize, and never the pedals themselves.  Within the case of Garmin & Favero, you’ll get crimson cleats which have 6-degrees of float in them.  Within the case of Wahoo, the cleats have adjustable float from 0-15 levels.

Max Rider Weight:

Lastly, some pedals are restricted when it comes to how heavy the rider could be.  In fact, t.’s not really a rider weight restrict, however relatively an output wattage restrict.  Besides making that clear to customers could be a nightmare.  So as an alternative they do math backwards a bit since normally, heavier folks can output extra energy than lighter folks with the identical quantity of effort.

Now t.’s actually two facets at play ..  First is the safety-focused facet of the pedals breaking.  However that’s probably not of concern ., these pedals are just about high-quality for anyone within the ballpark of those weights.  For these firms the true challenge is breakage of the sensors inside the pedal above a given threshold.  Right here’s the acknowledged max rider weights:

Garmin Rally & Vector Collection: 105 kg (231 lbs)
Favero Assioma: 120 kg (265 lbs)
SRM X-POWER: No sensible restrict in keeping with SRM
Wahoo POWRLINK Zero: 113kg (250lbs)

Obtained all that? Good, let’s speak cornering.


Subsequent, we’ve obtained the affect of pedal dimension/design on cornering.  This will get as to whether or not your crank arm would hit the bottom whereas making a decent nook, doubtless in a race.  Particularly, that is in the event you pedaled by way of the nook, and/or had stupidly positioned your crank arm down on the facet closest to the nook.  The priority grows better with longer crank arms, and is much less of an issue with shorter crank arms. And naturally, the peak of your backside bracket from the bottom (larger means much less chance of hitting).

This was a enjoyable one to measure.  In my case, I’m working 175mm crank arms, which is barely longer than the ‘common’ of 172.5mm crank arms.

As a way to measure this, I positioned the arm straight down, after which measured the angle as soon as the pedal, whereas flat, hit the bottom.  I used an iPhone with a stage app that I validated first on a stage floor.  Then I used a cellphone mount to maintain it steady/sturdy whereas doing every take a look at consecutively. Bear in mind, these are some fairly darn steep angles. I don’t assume folks understand simply how far you need to nook to clip ..

Listed here are all of the pedals, as seen on a highway bike (you’ll have totally different numbers on a mountain bike):

Garmin-SPD-SL-Cornering Garmin-KEO-Cornering FaveroAssioma-Cornering

Garmin-SPD-Cornering SRM-X-Power-Cornering Wahoo-Powrlinkzero-Cornering

Or the summarized stats .:

Garmin Rally SPD: 36°
Garmin Rally SPD-SL: 37°
Garmin Rally LOOK KEO: 37°
Favero Assioma LOOK KEO: 38°
Favero Assioma SPD-SL: 37°
SRM X-Energy SPD: 37°
Wahoo POWRLINK Speedplay: 39°

In a phrase, they’re principally a wash aside from Wahoo, which presents a bit extra cornering on Speedplay pedals, however like weight, that’s tough too – as a result of once more, it’s transferred to the cleat, so that you’ll undoubtedly clip on that sooner as a result of the cleat is wider.

Now, the very first thing that shocked me was that the Favero Assioma Duo-Shi (SPD-SL variant with a 10mm longer q-factor) was just about an identical to the bottom Assioma. The SPD-SL variant was 37° (although sometimes flickering at 38°), w.because the inventory Assioma is 38°. Once more, regardless of being 10mm longer. Nevertheless, the secret’s trying on the underside of the pedal, w. the Ultegra Pedal tapers considerably on the edge (clearly, to keep away from this very challenge). W.because the Assioma pedal is principally a vertical wall on the underside edge – making the cornering angle far lower than it could be with a tapered design.

The second factor that shocked me doing it this time round was the distinction in cornering angles to my earlier bike. In a previous take a look at of this, I used to be getting 27-29° of cornering, however on this Cannondale bike I’ve been testing for one thing else (this bike was the closest to my digital camera after I began this fiasco), I used to be getting 36-37°. So, out of curiosity I then put my Canyon bike up towards the Cannondale bike, and regardless of having the identical crank lengths, the underside bracket is simply barely larger on the Cannondale, and each millimeter larger means an enormous quantity of additional cornering angle. So roughly 2mm larger backside bracket led to a ten° larger cornering angle. Loopy!


In any case, I confirmed this identical tactic in quite a few different opinions, and so far, I’ve seen just one particular person state they’ve hit their pedal on the bottom whereas cornering (to which another person instantly identified they’d in all probability have hit that pedal anyway, whatever the slight improve in stack peak). And now we’re some 7+ years down the highway on energy meter pedals, and this merely isn’t a real-world challenge for 99.99% of individuals.

Battery and Broadcasting:


Subsequent, we’ve obtained a slate of technical particulars from battery to broadcasting, together with facets round ANT+ & Bluetooth Sensible requirements.  First up is how the darn issues are powered.


Every of the three pedals makes use of totally different battery choices, together with totally different energy outputs.  To simplify this, . are the three fashions:

Garmin Rally: 2xCR1/3N (one per facet) coin cell batteries
Favero Assioma: Rechargeable battery, encased, not swappable
SRM X-Energy: Rechargeable battery, encased, not swappable
Wahoo POWRLINK: Rechargeable battery, encased, not swappable

The CR1/3N battery isn’t tremendous straightforward to search out advert hoc in grocery shops/fuel stations, so it would be best to plan for that with maybe an additional in a saddlebag if travelling. Equally in fact, in the event you neglect your charging cable for the others, none of them are customary – so that you’re undoubtedly hosed t.. Favero, Wahoo, and SRM all have removable charging connectors, which then plug into both USB-C (Wahoo) or Micro-USB (SRM/Favero) cables.


As for battery life, you’re going to must go along with claims . as the usual. Primarily based on my testing, in addition to others, all of those appear to be within the appropriate ballpark insofar as real-world expertise. In fact, issues like temperature will affect that – however no person at this level is an outlier in relation to lacking the ballpark of their claims.

Garmin Rally: 120 hours (with Biking Dynamics enabled)
Favero Assioma: 50 hours
SRM X-Energy: 30 hours
Wahoo POWRLINK: 75 hours

Word that SRM’s official declare is 30 hours, although in idea on their newer {hardware} internals, it must be getting within the 40-50hr vary. I haven’t examined the newer battery internals although.

Now, in relation to rechargeable batteries, some have issues.  I’m going to rapidly copy/paste what I wrote within the Assioma assessment under – because it actually applies to all items. However in the end it’s only a private preferences factor.

From the Favero Assioma In-Depth Overview: I’ve seen some concern about what occurs when the batteries ‘die’, apparently in reference to the way you would possibly swap them out.  A few of this is because of misunderstandings about how rechargeable batteries die.  First off is that batteries are typically rated to a sure variety of recharge cycles, within the case of the Assioma battery, that’s estimated to be about 500 cycles (per Assioma).  As soon as it reaches that quantity, they don’t cease working.  As a substitute they could slowly degrade, maybe to 80% of battery capability.  With a battery life of fifty hours, and the five hundred recharge cycles, that places you at 25,000 hours of battery life earlier than it begins to degrade.  That’s 24 years of driving 20 hours per week.  Or virtually 50 years in the event you rode 10 hours per week.  Significantly, you’ll have lengthy moved onto one thing else by then.  Battery cycle time will not be your concern ..

Standing LEDs:


All 4 items include standing LEDs that permit you to validate primary operation.  These lights are additionally used for issues like firmware updates and such to let what’s occurring.  On the Rally and SRM pedals you possibly can see it on the finish of the spindle (inexperienced gentle), on the Favero & Wahoo pedals, the lights are on the pods themselves. Additionally, getting this image with all of the LEDs illuminated took an astounding period of time.

Fundamental ANT+/Bluetooth Sensible Connectivity:

Subsequent is how and what every unit transmits, beginning with probably the most staple items on this mini-section, after which shifting to the extra advanced stuff within the subsequent mini-section.  Merely put, all three items broadcast all the identical core fundamentals. They virtually all broadcast the next information through the ANT+ & Bluetooth Sensible requirements:

ANT+ Whole Energy
ANT+ Energy Stability (Left/Proper)
ANT+ Cadence (RPM)
ANT+ Torque Effectiveness [Not Wahoo]ANT+ Pedal Smoothness [Not Wahoo]Bluetooth Sensible Whole Energy
Bluetooth Sensible Energy Stability (Left/Proper)
Bluetooth Sensible Cadence

T. are not any official requirements for Bluetooth Sensible Torque Effectiveness or Pedal Smoothness right now. Word that each one items permit for limitless concurrent ANT+ connections (e.g. a motorbike laptop and Zwift each connecting on the identical time). On the Bluetooth connection facet, Favero and SRM solely permit a single concurrent Bluetooth Connection. Garmin permits for 2 concurrent Bluetooth connections, and Wahoo permits for 3 concurrent Bluetooth connections.

In relation to head items, inside the core settings above, all respected head items assist all these totally different objects.  One caveat although is Bluetooth Sensible-only head items could be a bit extra tough, as oftentimes they’ll solely pair to a single facet of a twin sided energy meter.  This will present itself in bizarre methods on sure older watches and bike computer systems (particularly older Polar & Suunto watches).

As a basic rule of thumb, most within the energy meter trade would suggest utilizing ANT+ over Bluetooth Sensible when connecting to your head unit, regardless of the unit broadcasting each.  The exception to that being in the event you expertise drop-outs out of your energy meter to go unit (not one of the items . although are vulnerable to that), by which case you may attempt to see if Bluetooth Sensible will resolve the drop-outs.

Of notice is that metrics like TSS (Coaching Stress Rating), NP (Normalized Energy), and plenty of others are under no circumstances energy meter mannequin dependent.  Somewhat, they’re depending on the particular head unit and/or coaching platform you utilize.

Superior Pedaling Metrics:

Now along with the core energy metrics seen above, two of the fashions have totally different superior metrics that may be proven.  These embrace Biking Dynamics, which each Garmin and Favero leverage utilizing that customary profile (albeit, to totally different levels). SRM additionally has some superior pedaling metrics, although these are solely seen inside their particular app.

Biking Dynamics: This beforehand began off as a Garmin-only factor, however then was introduced forth into an ANT+ customary. These metrics are displayable on a head unit (albeit at current, solely Garmin has applied it) in addition to afterward in Garmin Join.  Additional, third events may show the info too.  These metrics span a large variety of areas from platform heart offset to seated/standing time.  A few of these metrics can be utilized in bike match, whereas others are clearly extra geek-oriented.

First up, is all of the charts you get on a traditional journey – you’ll see the cadence/energy/steadiness, after which the seated/standing place bits of Biking Dynamics are blended in t.. Beneath is what you’ll see from a pair of Garmin Vector or Rally pedals:


As you scroll down, you transition totally into the Biking Dynamics associated bits (Platform Middle Offset, Pedal Section):



However t.’s additionally a secondary tab t., to see all of the Biking Dynamics .rmation:


For instance, I can inform you my max and common energy for each whereas I’m seated versus standing.  T.’s doubtless one thing to be discovered from that, however principally it’s only a enjoyable geek stat – I don’t use it day-to-day. facets like PCO (Platform Middle Offset), could possibly be helpful for taking a look at whether or not or not your bike match is correct.

In complete t.’s an enormous record of Garmin Biking Dynamics metrics you could add/document.  They’re:

PCO, PCO – Avg, PCO – Lap, Energy Section – L, Energy Section – L. Avg, Energy Section – L. Lap, Energy Section – L. Peak, Section – L. Peak Avg, Section – L. Peak Lap, Energy Section – R., Energy Section – R. Avg, Energy Section – R. Lap, Energy Section – R. Peak, Section – R. Peak Avg, Section – R. Peak Lap, Time Seated, Time Seated Lap, Time Standing, Time Standing Lap, Common Energy Standing, Max Energy Standing, Common Energy Sitting, Max Energy Sitting, Common Cadence Standing, Max Cadence Standing, Common Cadence Seated, Max Cadence Seated.

Now, with all that backstory, notice that whereas Garmin Vector/Rally assist all of those metrics, particularly the Favero Assioma pedals don’t assist Platform Middle Offset (PCO). Wahoo doesn’t assist any of them, as they acknowledged they don’t see worth in them. As a substitute, Wahoo says they’re engaged on another type of superior pedaling metrics for down the highway. However no timelines or particulars can be found for what that is likely to be, or when it would present up.

Energy Accuracy:


T. are numerous unhealthy energy meters within the energy meter trade, each ones in manufacturing – however principally ones that by no means fairly made it to manufacturing. Nevertheless, this set of 4 energy meter pedals don’t fall into the bad-camp (no relation to band-camp). I take advantage of and have used all 4 units of those pedals for prolonged intervals of time (almost a 12 months for Wahoo POWRLINK, greater than a 12 months for Garmin Rally, almost two years for SRM X-Energy, and almost 5 years for Favero Assioma) – and all of them are stable on accuracy throughout all kinds of situations. Word that within the case of the SRM pedals, that goodness assertion solely applies to the SRM X-Energy sequence, and never their SRM EXAKT Look-KEO sequence from earlier efforts, which I don’t belief in any respect (that was a collaboration with LOOK, based mostly on older know-how as a part of a collaboration from Polar a few years prior).

Formally every firm makes barely totally different accuracy claims:

Garmin Rally: +/- 1.0%
Favero Assioma: +/- 1.0%
SRM X-Energy: +/- 1.5% (that is additionally listed as +/- 2.0% in some locations)
Wahoo POWRLINK: +/- 1.0%

Which isn’t to say that each single journey I’ve performed has been good. With sufficient rides over sufficient years, I can often ultimately discover some quirky one-off journey that doesn’t match the mould of expectations in some nitpicking approach. However that’s additionally true of just about each energy meter or coach in the marketplace, some greater than others. Nevertheless, I’ve no points with taking these items out and utilizing them both day-to-day for coaching – or extra importantly on this context, day-to-day for accuracy testing – particularly in the event you comply with easy pre-ride zero-offset procedures.

Comparability Tables:

This part is a extra simplified model of this submit. Mainly, it’s the core variations between all these items in a single tidy place. Nevertheless, this chart under is definitely pulling from the bigger product comparability database, with quite a few different energy meters of different sorts in it. You possibly can all the time make your individual comparability charts within the product comparability database, however for simplicity I’ve included a few primary comparisons under.

And once more, keep in mind you possibly can all the time make your individual comparability charts within the product comparability database.



In some ways, that is half long-term assessment, and half purchaser’s information. I’ve had all of those pedals on bikes for actually lengthy occasions. Each when it comes to bikes that I take advantage of inside my testing rotation, but additionally on my ‘main’ bike that I take advantage of for basic driving. Beginning with accuracy, as famous above, I can swap between any of those pedals and know that I’ve obtained a very good accuracy baseline to work from.

The following bit is reliability and dependability when it comes to battery life and connectivity. And once more, most of those are stable – with solely the SRM X-Energy being on the decrease finish by a good chunk. It’s obtained different weight advantages within the SPD realm in comparison with Garmin’s providing, which can be a consideration for you. However when it comes to reliability of the pedal waking up and doing what it’s presupposed to do – all of those match that invoice. And I don’t see dropouts or connection points with any of those, utilizing dependable bike computer systems/watches.

Subsequent, we’ve obtained the mechanical facet. Once more, all of those pedals I (and plenty of others) have put by way of numerous hours or years of utilization with out a lot challenge from what I’ve seen. If we take a look at the Garmin Vector 3 points round battery caps, that was solved greater than a 12 months in the past with new stronger caps that accepted new battery sorts to eradicate that challenge (and downstream points), which is in flip the very same cap that Rally makes use of.

After these, we now have cleat-related stuffs. Clearly, that’s going to rely upon what you utilize. Nevertheless, in the event you do use a number of cleat sorts all year long and wish flexibility to change between these, the Garmin Rally system is the one possibility that does that. However that does rely upon you having some seasonality to your bikes/cleats. And realistically, it’s far cheaper to get a crankset-based energy meter for a secondary bike typically – particularly for mountain or gravel bikes which have a single chainring.

And in the end, except for the Favero pedals, for a lot of the different pedal techniques ., you possibly can typically purchase two crankset spider-based energy meters (not crank-arm ones) for the value of lots of the dual-sided pedal techniques. Crank spider techniques provide you with appropriate complete energy, and aren’t vulnerable to among the crank-arm accuracy points on newer Shimano cranks. Which, isn’t meant to persuade you that pedals are improper after studying an enormous submit on pedal-based energy meters, it’s to level out pedals aren’t the one possibility.

T.’s good causes to get pedals – specifically portability, the flexibility to maneuver them between bikes. Or to take it with you while you journey with out a bike to stay on a rental.
