Technology Highlights
✓Wide 11-34T range. A proper climbing gear without giving up the top end, which is why this stayed the default XT 10-speed cassette for years.
✓HYPERGLIDE profiling. Shaped ramps and pins move the chain across under load, so shifts stay smooth when you are actually pushing.
✓Aluminum spider and lockring. Saves weight while the sprockets themselves stay steel for wear life.
✓Deore XT durability. The 10-speed XT cassette riders keep going back to when a drivetrain needs refreshing rather than replacing.
