Shimano Dura-Ace is the benchmark for superior shifting, braking, and durability, and the latest group takes performance to new heights. Every component in the Shimano Dura-Ace 9100 Groupset has been refined and redesigned for smoother and crisper shifter, even better braking, more efficient power transfer, and greater range of gearing.
Up front, Dura-Ace 9100 shifters are completely redesigned. At first glance, the changes to the shifter bodies are noticeable. Ergonomics have been refined, and a new hood material is used for additional comfort and grip. Shift-lever-throw has been reduced and lightened, making for quicker shifts, and the brake levers offer additional reach adjustment. Front shifting is further enhanced through a completely redesigned front derailleur. The aesthetics are much more streamlined, and it now offers a built-in cable tension adjustor. Out back, the rear derailleur features the most striking visual changes of the group. The 9100 rear derailleur takes design cues from Shimano’s M9000 XTR group, and includes features such as Shadow technology (ultra-low profile design). The Dura-Ace 9100 crankset builds upon the previous generation’s high standards. The cranks feature even larger Hollowtech II crank arms, for greater stiffness, and the 4-bolt chainrings bolster their already best-in-industry stiffness. Shimano continues its versatile 4-bolt design that allows for all chainring sizes to fit on a single crank-arm BCD design. Switching between a standard 53/39 crank and compact 50/34 only requires new chainrings to be purchased. The cassette and chain see small revisions to the previous-generations exceptional design, most notable is an additional cassette option of 11-30T, for lower-than-ever gearing. Finally, the already-excellent Dura-Ace brakes improve with additional tire clearance (now 28c), and smoother, more controlled operation.
The Shimano Dura-Ace 9100 Groupset builds upon an already amazing R9000 group, improving nearly every component for even better performance. We’re offering the Dura-Ace R9100 groupset as a 8 piece group, and includes 9100 dual control levers (shifters), braze-on front derailleur, rear derailleur, standard-mount brakeset, crankset (your choice of length and chainrings), chain, and cassette (your choice), and bottom bracket. Shimano’s Dura-Ace 9100 Groupset now features a Black finish.
