The Shimano Ultegra CS-R8101 Cassette is a 12-speed cassette spanning an 11-30T range, built for Shimano Ultegra road groupsets. It uses HYPERGLIDE+ technology, first developed for off-road cassettes, to move the chain between cogs during pedaling without needing to ease off power.
Larger cogs across the cassette work with both 11-speed and 12-speed Shimano FREEHUB bodies, keeping the cassette compatible with existing wheels during an upgrade. The gear steps are set for consistent spacing across the block, supporting steady cadence from climbs to flat sprints.
