The Ultimate XTR CS-M9100-12 cassette from Shimano


Made in Japan 


The starting point for the new development of the XTR in the drive area was for Shimano the goal to realize the lowest possible switching steps so that the cadence jumps when switching remain as small as possible, rhythm and propulsion are maintained and ultimately the speed is maintained. The result was a large 51-tooth sprocket that maintained the uniform difference of 6 teeth per gear in the small gears (10-12-14-16-18-21-24-28-33-39-45- 51 Z). 

The 10-51Z cassette is the ideal choice for trail riders who can tackle even the steepest ramps ,

The largest sprockets are made of aluminum, the middle of titanium and the smallest of steel.
