The Shimano FC-R8100 crankset is part of the Ultegra series and is designed for road bikes. Hollowtech II technology combines an integrated axle with hollow aluminum crank arms, helping reduce weight, provide stiffness and transfer power more efficiently while pedaling.
The chainrings mount on an asymmetrical four-arm spider with no visible external bolts. The external bottom bracket bearings help distribute weight, provide stability while pedaling and transfer power. It is compatible with Shimano 2x12 road groupsets and also accepts Shimano Dura-Ace R9200 chainrings.
