Miche X2 RD R81: gear designed to be lightweight, rigid and capable of transferring every watt with absolute precision. It was developed for the Ultegra 8100 cranksets with three different targeted configurations 50, 52 and 54 teeth.
Miche X2 RD R81: the key to this gear lies in its meticulous engineering and great attention to detail. A CNC machined AL 7075-T6 aluminum sheet merges with a 3 K carbon structural sheet, creating alchemy to create a unique combination that provides extreme rigidity, light weight and transmission with the highest level of reactivity. The dedicated design makes them compatible for cranksets with or without power meters, ensuring impeccable performance in every configuration.
