The Shimano CS-8100 XT 12 Speed cassette is the centre of Shimano's new 12 speed drivetrain. With a smooth gear ratio offering a huge 10T-51T range there is no climb or descent across Australia you won't be ready to crank down. Combine this with Shimano's reputation for reliability and a ridiculously sharp price, the Shimano 12 speed XT cassette and whole 12 speed range offer performance far above its pay grade.
