Shimano Deore FC-M4100-2 crankset - for 10-speed drivetrains

The Shimano crankset FC-M4100-2 from the Deore series are a cranks with two chainrings for 10-speed drivetrains. It is suitable for both MTB and City & Touring use. The chainrings are mounted via a conventional 4-arm spider. At 48.8 mm, the chainline, i.e. the distance from the frame to the centre between the chainrings, is in the standard range, which is why the crank is compatible with 142 mm over locknut dimensions. The 2-piece construction provides a balanced ratio of stiffness to weight.

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.

Sehr schickes Design. Hab die Kurbel gekauft und das Cube meiner Frau von 3x8 auf 1x11 umzubauen. Hatte noch ein SLX Schaltwerk inkl. Schifter und 32T Kettenblatt.
Also diese günstige Kurbel gekauft,XT Innenlager dazu, die vorhandenen Kettenblätter demontiert und das 32T drauf. Fertig war der Umbau.
