The new Shimano SLX SM-CRM75 chainrings with direct mounting system for SLX FC-M7100-1, FC-M7120-1 and FC-M7130-1 1x12-speed cranks.

In addition to a new special 12-speed chain (CN-M7100) with the corresponding new 12-speed QUICK LINK lock, SHIMANO is also equipping the SLX M7100 with new cranksets for 12-speed (FC-M7100/7120/7130-1). Most of them use 1-speed systems and a range of chainrings (30T to 34T) is available.

The new SLX 1x12-speed cranks are characterised by DYNAMIC CHAIN ENGAGEMENT+ technology, whose special high-precision tooth profile ensures that the chain finds optimum grip on the upper part of the chainring on rough terrain, but detaches equally well from the chainring at the bottom, thus ensuring efficiency, smoothness and low noise of the drive. The cranks are equipped with a direct-mount system for quick and safe assembly of the chainrings, enabling chainrings to be changed in no time at all. The crank is available in boost and non-boost specifications.

After setting the benchmark in mountain bike components with SHIMANO XTR M9100 and new DEORE XT M8100, Shimano rounds out its now entirely 12-speed performance mountain bike component lines with new SLX M7100. SLX M7100 cascades technology from new XTR M9100 and DEORE XT M8100 - namely Shimano’s signature premium shifting and braking performance - while maintaining the SLX hallmark of value and durability.
