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.…

SRAM 11 36 Cassette + Shimano Ultegra R8000 Medium Cage

As a flatlander who likes to climb, I’m always on the lookout for some mechanical advantage which can make it easier to get up the hills. SRAM’s 11-36 cassette is an obvious way to do that, but officially my Shimano R8050 (R8000 should be the same) rear mech only supports up to 34 in the back. Having tried the Ultegra 11-34, and not being a big fan, if this works. It seems…

Shimano Dura-Ace R9100 175mm 50/34 weight

As a confessed weight weenie, I generally try to find the weight of components before impulsively buying it. There are a couple reasons for this: first it helps slow down the process (i.e. fewer things that I need to explain to my partner later), and second if I’m going to add weight to the bike I want it to be a conscious, measured decision. So it was quite frustrating that I wasn’t…
