The Shimano XTR CS-M9101 cassette is characterised by its Beam Spider construction which enables enormous weight savings and at the same time promises long durability. Not only the spider but also the three largest sprockets are made of aluminium. The highlight, however, are the 5 medium sprockets made of titanium. The incredibly light cassette also features the Hyperglide+ technology which guarantees high shifting speed, precision and smoothness when shifting up and down and contributes to an extremely quiet drivetrain.
