Official Shimano Alfine FC-S501 Crankset w/ Double Bash Guard

Shimano Alfine crankset FC-S501 – with chain guard on both sides for your City bike

The Shimano Alfine FC-S501 crankset comes with a chainring (39 or 42 tooth) and two chain guards, which are mounted inside and outside. Whether silver or black – it looks simply great 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 so-called 2-piece design, which optimizes the stiffness and power conversion.

Technology:

2-Piece Crankset
With 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.
