Shimano FC-RS510 2x11 Speed Chainset

Lightweight 2-piece design 11-speed chainset.

2-piece design forged and anodised aluminium crank arms keep weight low.

The chainring teeth have been developed to work in conjunction with HG-X 11-speed chains for increased contact to provide greater efficiency and improved power transfer.

Bottom bracket bearings are spaced wide apart, enabling the use of larger bearings and an increased axle diameter. Chainring spacing has been optimized for use with 135 / 142mm rear axle spacing and short chainstayes.
