Shimano Dura-Ace R9100 3-Piece Upgrade Kit

While many consider Shimano's Dura-Ace 9000 the pinnacle for mechanical road groups, what we see with R9100, is a natural refinement of this original perfection. The rear derailleur has a slightly longer cage for fitment of a 30T cassette and receives the low-profile Shadow treatment. The cassette is now available in 11-30T, which allows for more climbing ability.

The kit includes the three pieces that make up the absolute core of your drivetrain; RD-R9100 rear derailleur, CS-R9100 11-30T cassette and CN-HG901 chain.


  • Core drivetrain kit
