Shimano Dura-Ace FC-R9200 12-Speed Crankset

There is nothing in this world like a shift on a Shimano front setup. Even their old mechanical stuff worked like butter, but the Di2 setup is nuts. Shifts every time, quiet, smooth, can do it one-handed, it's the best.

The crankarms themselves I have no issues with, even with the recall going around. The rings are where the magic happens, and it's worth it to me to not think twice about a front shift, or grinding it out a bit more in the big ring just to avoid that dreaded potential drop from other setups.

Great crankset. Catch a sale and treat your bike.

The one and only thing that you can get as a performance gain from using Shimano cranksets, is the ridiculously good shifting. They're crankarms, they spin around and you don't really notice something being stiffer, more aero, etc. But when you shift a Di2 Shimano front derailleur, on their rings, the system just works.

I can't really fault anything with them, I know the recall made people scared and the aftermarket brands are getting more traction, but I wash my stuff and take care of it, and the lifespan at the point of something snapping in half under my 70kg frame is way beyond my caring level.

Shimano stuff is expensive, especially the DA level stuff. If you have the money and realize it's doing nothing for you in terms of performance, have at it, it's your money do what you want with it. I go for Shimano for the shifting, I swear it works so well you forget about it.

Great product, average value, but it's on my bike either way right now.

Went for the longer version 177.5mm, for my long legs. Easy installation. One of the few things you can install and forget about, for a very long time.

Upgraded my 11 Speed Dura-Ace with 12 Speed. Curious about the new design / mfg.

Like with all Shimano products - It just works + Looks great too.

It shifts faster than 11 speed which is pretty amazing.

Happy with the purchase
