The new Shimano XT SM-CRM85 chainrings with direct mounting system for XT FC-M8100-1, FC-M8120-1 and FC-M8130-1 1x12-speed cranks.
The original mountain bike group continues its legacy: the XT SM-CRM85 Chainrings from Shimano
In addition to a new special 12-speed chain (CN-M8100) with the corresponding new 12-speed QUICK LINK lock, SHIMANO is also equipping the XT M8100 with new cranksets for 12-speed (FC-M8100/8120/8130-1). Most of them use 1-speed systems and a wide range of chainrings (28T to 36T) is available.
The new XT 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.
The original mountain bike group continues its legacy of remaining the standard for mountain bikers everywhere. Nearly three decades in, the DEORE XT brand is defined by its trail-tested durability, reliability and performance. Recognizing that today’s mountain bikers are riding faster and confidently on more technical terrain, the legacy of DEORE XT is more important than ever. In 2019, our pinnacle mountain bike technologies will trickle down to SHIMANO DEORE XT M8100.
