1 review for Shimano Dura-Ace RD-R9100 rear derailleur short cage with an rating of 4/5 point.
Excellent clean crisp shifting. Nice neat modern design. Huge improvement in shifting over my previous system. Changes feel shift and precise. No issues using KMC chains and after market chainsets also. Would be great to see the range increase to 32T in future..... ★★★★★ Robert
