Product Description Shimano Deore crankset FC-M6100-1 - for an uncomplicated set-up The Shimano Deore crankset FC-M6100-1 is for 12-speed drivetrains and comes with a single chainring for direct mounting. Ease of use, reliability and quick chainring changes are the main advantages of such a set-up. The Dynamic Chain Engagement+ technology, which was previously used on the SLX, for example, ensures that the chain runs securely, smoothly and quietly over the teeth. The chainline, i.e. the distance between the frame and the chainring, is 52 mm for this model, making it compatible with 142 mm and 148 mm over locknut dimensions. Last but not least, the FC-M6100-1 scores with its metallic look including colour gradient in the Deore logo and with the 2-piece design, which ensures a balanced ratio of stiffness and weight.

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. Dynamic Chain Engagement+ Dynamic Chain Engagement+ is Shimano's term for a special tooth profile of single chainrings intended for off-road use. This improves the chain hold and counteracts chain drop on rough ground. It also minimises wear and increases pedaling efficiency.
