Highlights
Description
The Shimano FC-RX820 crank balances weight savings, optimized efficiency and an array of gearing options that cater to the segmented demands of mixed-terrain riding. Riders can choose closer gear steps or ultimate range depending on personal need by pairing a 10-45t or 10-51t cassette with 40t or 42t chainring (cassettes and 42t chainring sold separately). Optimal gearing for mixed-terrain riding. Hollowtech II crank arms provide strength and stiffness with the benefit of weight savings. Compatible with HG 12-speed chains. 49.7mm chainline. 151mm Q-factor.
