Why We Like The Dura-Ace Di2 ST-R9150 11-Speed Shifters

As the rest of the industry scrambles to catch up, Shimano's Di2 groupsets continue to set the standard for precise electronic shifting with nearly endless customizability. The release of 9150 is the next evolution of Di2, bringing slightly updated aesthetics and even better shift functionality to your next ride. The Shimano Dura-Ace Di2 ST-R9150 11-Speed Shifters sit at the helm of your cockpit to drive precise shifts exactly when you need them.

The hoods take on a similar shape to 9070, but with a few slight tweaks for improved comfort when your hands are on the hoods. Made from a dual-compound rubber composite, the low-volume hood design retains the slightly perforated form of 9070 and makes lever accessibility easy. The lever blades and paddles see an outward curve and feel that's slightly more pronounced than in the prior generation, which makes for a more positive interaction from either the hoods or drops. Shimano also incorporates a more noticeable "click" feeling when shifting, which addresses the almost too-stealthy shift feel that was one of the few complaints we've fielded about previous Di2 systems.

Aside from those tweaks, the Dura-Ace 9150 shifters deliver the precise, swift gear changes we've come to expect from Di2. Shimano even claims that this version might even be a little bit faster, but frankly, we have a hard time qualifying that claim when we're out on the road. Both shifters allow a customizable shifting experience dialed to your riding style and requirements, including the ability to dump through multiple gears—or even the entire cassette—with one shift movement. And for the proverbial icing on the cake, when paired with the new 9150 rear derailleur, these shifters are now capable of performing shifts up to a 30t cog on the cassette.

>Rating: 5

THE best.

I've put it through the wringer

I've ridden them all, recently even, and I'm back on Shimano. The reaction is faster, smoother, precise, it's just the best electronic groupset out there. The ergonomics of the the shifters is outstanding. Highly recommended. If you have any questions on your build feel free to reach out to me directly

Amazing Ergonomics

Let me just list all the electronic systems I've had the opportunity to own/work on: Campagnolo Super Record EPS Campagnolo Record EPS SRAM eTap All generations of Shimano Di2 (6770, 6870, 7970, 9070, R9150) Out of all of them, my favorite lever shape and button tactility is going to be the R9150. If you've tried the older Di2 levers, you may have been disappointed with how wimpy the clicks are. Well Shimano actually listened and this newest generation feels really solid. eTap feels hollow compared to this. Campy is nice, a little bit muted, solid as well, but not everyone is a fan of the thumb shifters. Feel free to reach out with any questions!

do the calipers come with it
