Shimano Ultegra FC-R8100 Hollowtech II road crankset, 2 × 12-speed, 52-36T, 172.5 mm (IFCR8100DX26).
- Hollowglide outer ring, grey/black finish
- 110 mm BCD, 24 mm axle, 148 mm Q-factor
- Bottom bracket not included
The Shimano Ultegra FC-R8100 is the 12-speed road crankset from Shimano’s Ultegra R8100 group. This one has 52-36T chainrings and 172.5 mm crank arms in Ultegra’s grey/black finish.
Shimano’s Hollowglide outer chainring is hollow to save weight while staying stiff, for quick, precise front shifts and efficient power transfer. 52-36 suits fast group rides on Al Qudra and the flat loops around Dubai, while the 36T inner ring still handles climbs like Jebel Hafeet with a wide-range cassette.
Check these before you order
- 12-speed only — use a Shimano 12-speed HG chain and a 12-speed road front derailleur such as the Ultegra Di2 FD-R8150.
- Bottom bracket not included. It needs a Shimano Hollowtech II road bottom bracket for a 24 mm axle — threaded (68 / 70 mm shells) or press-fit, to suit your frame.
- Crank length: 172.5 mm. If unsure, match the length printed on the inside of your current crank arm.

Who it is for
- Road riders upgrading to 12-speed Ultegra
- Replacing a worn or damaged crankset on a 12-speed Shimano road bike
- Riders who prefer standard 52-36 race gearing

No. You need a Shimano Hollowtech II road bottom bracket that suits your frame.
52-36 or 50-34?
