Crank Length: 170mm

Ratio: 50/34t

Overview

The redesigned mechanical Dura-Ace drivetrain calmly holds its own in this brave new world of wires, batteries, and display screens.

It's fitting then, that the DURA-ACE FC-R9100 11-Speed Crankset also comes with the double chainrings that many roadriders despise to abandon just yet. Call upon your granny gear when needed with this lighter, stronger version of a top-end classic, and embrace a tried-and-true tradition of cables. Of course, in the even that you do decide to run electro-shifting, the crank's ring profile plays just as nicely with Di2 derailleurs.

Highlights

1 - The crank and spider arms are noticeably bigger, increasing the stiffness and strength. However, the overall weight has dropped by 7g over the previous edition of Dura-Ace.

2 - The crankset has been modified to work with disc brake road bikes that generally have 135mm rear hub spacing and shorter chainstays without the need to increase Q-factor thanks to its wider chainring spacing.

3 - The Compact version offered here features a 50.34T chainring profile to offer an excellent rider tuned gear combination for varied conditions from flats to high mountains.
