Shimano Alfine crankset FC-S501 - with one-sided chain guard for your City bike
The Shimano Alfine FC-S501 crankset comes with a chainring (39 or 42 teeth) and a chain guard ring that is fitted externally. Whether black or silver - it simply cuts a fine figure on city bikes and touring bikes with 8- or 11-speed internally geared hubs. The 5-arm aluminium crank with 130 mm bolt circle diameter features the 2-Piece Design, which optimises the stiffness as well as power conversion.

Technology:
2-Piece CranksetWith the 2-piece designed cranks from Shimano, the right crank arm is precisely matched to the interaction with the bottom bracket. This increases the stiffness and keeps the weight low. Further spaced bearings also improve strength and contribute to more pedalling efficiency. The precision manufacturing of the bearings ensures easy installation and low maintenance. 2-Piece cranks share a 24mm axle diameter with Hollowtech II cranks, so they are also compatible with Hollowtech II bottom brackets.
