Shimano Deore FC-M6120-1 Crankset

Shimano Deore crankset FC-M6120-1 - 1x12-speed cranks for wide frames

On the Shimano Deore crankset FC-M6120-1 for 12-speed drivetrains, the chainline, i.e. the distance between the frame and the chainring, is 3 mm more than on the FC-M6100-1 cranks. It is therefore 55 mm, which makes this model compatible with 148 mm over locknut dimensions. FC-M6120-1 is equipped with a single chainring for direct mounting, so Mountain bikers benefit from a user-friendly, reliable and low-maintenance set-up. To ensure that the chain runs safely, smoothly and quietly over the teeth, Dynamic Chain Engagement+ technology is used, which was previously used in the SLX, for example. Last but not least, this crankset scores points 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.

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.

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.
