Shimano Forces Hammerhead to Remove All Di2 Related Functionality From Karoo-NEWS SNEAKERS

Efficient subsequent Thursday, Hammerhead will take away all Di2 performance from the Hammerhead Karoo sequence, through firmware replace. That is on the request/demand of , who in line with Hammerhead, now sees them as a competitor. This implies all Di2-related performance together with Di2 battery standing, gear indicators, web page modifications through Di2 hood buttons, and shifter mode, will all be eliminated.

Right here’s a quote from Hammerhead outlining the difficulty:

“The modifications come on the request of . offered a license settlement Hammerhead was granted permission together with technical particulars enabling the connecting of the Hammerhead units with the Di2 system. Hammerhead supplied to proceed supporting Di2 customers with full performance after the SRAM acquisition, however in the end, Shimano recognized SRAM as a competitor and the contract was terminated at Shimano’s request.”

In different phrases, that is completely a results of SRAM buying Hammerhead earlier this 12 months. Hammerhead goes on to say that “Hammerhead has reached out to Shimano and is open to resuming help of the performance.” – nevertheless, in speaking to Hammerhead, it doesn’t sound like this has gotten anyw.. As for Shimano? I’ve tried to succeed in out to them, however I’ve but to listen to again.

Hammerhead has had this performance of their Karoo merchandise for practically three years. They first introduced it again on October fifteenth, 2019, CEO Pieter Morgan of Hammerhead stated on the time:

“Continued updates are a cornerstone of Karoo’s working system, which lives on essentially the most succesful and future-proof piece of {hardware} out there within the head-unit market. This partnership with Shimano permits the Karoo to serve racing cyclists higher than ever and additional secures Hammerhead’s place on the forefront of the {industry}” – Oct fifteenth, 2019

At this level, you could be questioning why a partnership is important in any respect? In spite of everything, you seamlessly join your energy meter, coronary heart fee strap, or different gear shifting sensors to any bike laptop you need, all with out eager about it. Sadly, this isn’t fairly like the remainder of these gadgets.

How the Sausage Is Made:

It’s vital to know that the best way bike computer systems hook up with Shimano Di2 gearing is considerably of an {industry} quirk. You see, again when Garmin and Mio first began connecting to Shimano Di2, t. was no such factor as the usual ANT+ Gear Shifting profile. As a substitute, t. was Shimano’s wi-fi implementation over what’s known as ‘Personal ANT’. Personal ANT is principally only a proprietary channel/language made atop the ANT wi-fi community. Numerous firms will stuff further .rmation into private-ANT. Typically huge issues, generally little issues.

For instance, when Garmin first rolled out Biking Dynamics for Garmin Vector pedals, they did so over non-public ANT. Ultimately, they turned standardized as ANT+. The identical was true for the Varia radar profile, now standardized. Or Operating Dynamics, now standardized.

And in the end, that’s truly what kinda occurred for gear-shifting too. Besides, Shimano by no means performed ball. As a substitute, we noticed SRAM and Campagnolo bounce onto the ANT+ Gear Shifting profile (together with Garmin and each different firm) and help that. The speculation again then was that Shimano would ultimately transition to it over time. In the identical manner, Garmin made minor behind-the-scenes software program tweaks to transition to plain variations of their beforehand private-ANT issues.


Whereas that lack of Shimano motion was annoying from a requirements standpoint, it frankly wasn’t too huge a deal for most individuals. Trade people may simply undertake each, and Shimano made them out there with relative ease. Shoppers didn’t actually care, and a few bike computer systems didn’t even separate out the distinction from a consumer-facing standpoint. So within the grand scheme of issues to be irritated about, it was a large shrug.

In reality, even Shimano’s personal Di2 related companions web page from 2021 (thanks Web Manner Again Machine) proudly shows Hammerhead together with a dozen different companions. Everybody used it, and the world gears stored spinning.


And whereas technically talking Shimano isn’t doing open-standards ANT+, they prefer to usually blur that line into making you imagine they’re doing open-standards ANT+. On that very same web page, should you scroll to the highest, they seek advice from ANT+ .. When in actuality, it’s very a lot not. In industry-speak, it’s analogous to the distinction between saying you use a for-profit enterprise, versus a non-profit charity.


What makes this specific dispute so fascinating is the competitors angle. Usually talking, the sports activities tech {industry} has finished a very good job of avoiding that individual angle when speaking requirements and implementations of these. As a lot as individuals usually prefer to allude to Garmin proudly owning ANT+ and such, the truth is, they really held a week-long occasion each single 12 months for over a decade purely to attempt to get competitor firms on requirements. And it labored. It labored tremendously properly.

In fact, t. have been all the time quirks and minor disputes. Or outright slowness. However by and enormous, the truth that your bike laptop truly works with the facility meter you purchased, is because of the work of all the businesses that created and adopted these requirements – irrespective of how they compete, and irrespective of how huge or small. However over the past 2.5 years since that convention stopped being held (primarily, however not completely, resulting from COVID). And in consequence, we’ve seen a gentle slide away from supporting requirements. One solely want to take a look at the quite a few makes an attempt by Zwift over the previous couple of years to power licensing agreements on firms for issues like steering or wired connectivity, regardless of the {hardware} firms being those that truly got here up with these requirements.

But it surely’s additionally on these identical {hardware} firms to place within the time to really create correct requirements, and cease kicking the can down the street. All of them received spooked with Zwift’s {hardware} plans, and created a consortium of the core indoor coach firms engaged on requirements agreements for among the areas I simply talked about. However that’s principally being held on the facet. T. isn’t any formal ANT+ or Bluetooth working group round that. And maybe that’s as a result of ANT+ TWGs (Technical Working Teams) have a well-deserved status for slowness, however once more, it’s maybe that slowness that in the end ensures success.

And that’s to not knock that group in any respect. In spite of everything, I’ve heartedly inspired it behind the scenes. However to level out that such efforts actually solely succeeded within the grand scope of time in the event that they’re formalized by requirements our bodies which can be seen as authoritative of their {industry}, by each firms in addition to customers.

Whereas Garmin has tried to shift elements of the ANT+ Symposium into the Garmin Developer Summit, the truth is, that simply hasn’t occurred. Nor, has it labored. T.’s a core purpose why these two occasions ought to stay separate, and each proceed onwards. As numerous individuals have stated, attempting to get rivals to come back inside your headquarters in Olathe, could be very totally different than getting 2 hundred {industry} individuals assembly collectively within the woods of Canada at a impartial resort with Molson in hand.

Going Ahead:


The truth of Shimano’s obvious determination is that it doesn’t actually damage Hammerhead as an organization, as a lot because it hurts Shimano customers. In spite of everything, the individuals getting screwed . are those that checked out Shimano’s personal web site and noticed the Hammerhead brand listed as a suitable accomplice. From t., they could have purchased a Di2-equipped bike due to it, figuring out the mixing existed.

Shimano doesn’t acquire something . competitor-wise by this transfer. It’s petty at greatest, and simply kinda silly at worst. Take for instance a Cannondale Synapse bike I’ve been testing these days for an unrelated put up. I prefer it, and it’s outfitted with Shimano Di2 and the most recent R9200 Dura-Ace drivetrain. And, I’ve even been utilizing it with the Hammerhead Karoo 2 as properly. In reality, this is without doubt one of the first occasions I’d truly take into account shopping for one of many bikes I’ve been attempting out. Besides now, I gained’t. Merely I’m not going to purchase into an ecosystem that limits what I can use with it.

Proper now, that bike is barely supplied outfitted with Shimano Di2. For what I do, I need open operability. Plus, who’s to say that Shimano gained’t resolve Wahoo or Garmin are subsequent? In spite of everything, they each make energy meters too. Positive, it’s seemingly Shimano is upset at Hammerhead as a result of SRAM makes drivetrains. However, in that quest for vengeance, they’re solely hurting their very own prospects, and their very own potential gross sales.

And in the end, this little kerfuffle is probably going only the start of extra spats except firms come again to the plate on requirements. With out them, we’ll see an increasing number of compatibility points for an space that frankly we haven’t needed to fear about for years.

With that – thanks for studying
