The C116 chainrings are compatible with Shimano XTR cranksets (from 2003 to 2006). These chainrings are the perfect replacement for the Shimano XTR M960 rings and are 25% lighter compared to the originals. The special PCD, only used on the M960 crank bolt pattern makes it difficult to find a replacement if the original rings are worn. For clean up-shifts, 4 shift pins are attached to the inside of the 44t ring. Produced in France. Technical data: Compatibility: only XTR M960. Number of teeth: 44 teeth. PCD: 146mm. Speed: 8, 9, 10x. Colour: Black, silver teeth.
