Get Di2 Back On Your Karoo 2

Remember how Shimano gave Hammerhead Karoo/Karoo 2 owners the shaft back in May? That has been corrected, at least for Karoo 2 users, by an enterprising fellow named Valter Costa who leveraged the Hammerhead SDK to add the functionality back into the device via an add-in.…

Install Shimano SW-R9150 Satellite Shifter on a Time Trial (TT) or Tri Bike

I was disappointed to discover that the Shimano Di2 system on my Trek Speed Concept didn’t have enough buttons to support manual shifting or D-Fly (i.e. changing pages on your Garmin). I can live without the manual shifting, but not D-Fly, so I set to figuring out how to add extra shifters to the aerobars on the bike. 12-Speed Considerations: 00:23 The Problem: 1:12 The Parts: 02:21 Cockpit Matters: 04:28 Installation Tidbits:…

Don’t be a dick, Shimano. Oh, too late…

I’ve generally had a very positive view of Shimano. For the most part, the kit just works. What’s not to like about that? Well, part of how it just works, won’t anymore because they decided to cut Hammerhead out of their Di2 licensing. Why? Because SRAM bought Hammerhead… Yep, Shimano is screwing every one of their Di2 customers that also has a Hammerhead bike computer. WTF?…

Shimano E-tube 5.0.3 Incompatible with SM-BCR2

I can get that Shimano is SUPER excited about their new 12 speed Di-2, but in that excitement they seem to have forgotten that the overwhelming majority of their Di-2 user base is running the previous generation. Most of these folks, are probably using the SM-BCR2 to charge and connect with the bike to do things like firmware updates, setup shifting, and configure the gears. Because if you don’t have a D-Fly,…

All your Shimano Dura-Ace 9270 Weight Questions Answered

I’m not sure if I’ve ever started a Rides of Japan video, and not watched it all the way through. Content I want, presented in a way that is easy to consume; what’s not to like? Today’s installment will be a bit dry for anyone not interested in the weight of bike components, or how to setup Shimano’s new semi-wireless Di-2 system, but for me this is perfect.…

Shimano Goes To 12, on the road

We all knew that Shimano was bringing 12 speed to the road, and it’s finally here… What comes as a surprise to me, is that they updated both the Ultegra (R8100) and Dura-Ace (R9200) groupsets at the same time. Wireless receiver is now in the rear derailleur. One one hand, this means you don’t need a separate D-Fly to integrate with the bike computer, but on the other, it means that Shimano…

Something about wireless Dura-Ace 9200

I debated posting about this when I saw it pop yesterday because it’s clearly speculation around something that may, or may not be, Shimano’s upcoming Dura-Ace 9200 [potentially wireless] groupset. Ultimately, I think the value of the comments around wired vs. wireless shifting that Keith drops in the there make it interesting enough to warrant some noise.…

One Cleat To Rule Them All

When I bought my first road bike, I briefly considered getting road shoes and pedals, but quite frankly I didn’t see the point. It’s nice to be able to walk in my shoes, not have to carry cleat covers, and now that I have a gravel bike it makes even more sense to have a single, unified, approach to shoes and pedals. Whatever bike I take, it’s the same cleat system, everything…

SlowTwitch creates ambiguity around Shimano Dura-Ace R9100P Power Meter

I must admit that I don’t frequent Slowtwich that often, and stuff like this is probably why. While I have zero first hand experience with the R9100P, it’s very clear (as in zero ambiguity) that this power meter doesn’t work. While some of this is inherent in the asymmetric design of the 9100 crank, most 9100 based power meters (e.g. Stages, 4iiii, Pioneer), while imperfect, at least function in a predictable way.…
