The XTR cassette features high switching performance, light weight and high wear resistance. The gearshifts are extremely precise, so that the Schaltpausen be very short. An intelligent mix of materials of aluminum, steel and titanium increases the service life, but at the same time reduces the weight of the cassette.
Thus, the base body is designed as a weight-saving aluminum spider. The top 5 sprockets are made of titanium, underlining the high demands on the life of the cartridge.
