Shimano Ultegra FC-R8100 Chainset

Shimano Ultegra FC-R8100 Chainset Redesigned for improved performance; the Shimano Ultegra FC-R8100 Chainset works with Shimano 12-speed drivetrains; providing increased chain contact for improved efficiency and power transfer. The cold-forged four-arm HollowTech II crank arms also help put all the watts down to the tarmac by managing to be both stiff and lightweight; thanks to their hollow aluminium construction. Shifting has also improved; with the HollowGlide outer chainring’s rigidity offering hugely impressive gear changes; no matter how much strain the drivetrain is under at the time. It still uses Shimano’s renowned HollowTech II bottom bracket for durability and smooth running and there is a wide range of crank lengths and ratios available.
