Stabilises the bike during maintenance
Stop pretending not to see your damaged crank every time you get on your bike so you don't get depressed...

The Shimano FC-R8100 left crank is compatible with the crankset from the same Ultegra 12-speed R8100 range. Available in 4 lengths – 165, 170, 172.5 and 175mm – it pairs with the right crank and chainrings to form a complete crankset.
Also compatible with cranksets from the same brand, such as the R7000 and R9100, the FC-R8000 crank arm will perform the same function as the original. The design will, however, be slightly different.
- Hollowtech II generation
