Shimano Deore FC-M4100-B2 Crankset

Shimano Deore FC-M4100-B2 crankset - with wider chainline

The Shimano Deore crankset FC-M4100-B2 for 10-speed drivetrains has a 3 mm further outward chainline compared to FC-M4100. This means that the distance from the frame to the centre between the chainrings is 51.8 mm instead of 48.8 mm, making the cranks compatible with 148 mm frame over locknut dimensions. However, the two chainrings are also mounted on this model via a conventional 4-arm spider. Thanks to the 2-piece construction, a balanced ratio of stiffness to weight is ensured.

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.
