SHIMANO ULTEGRA CASSETTE 12v 11-34 CS-R8100 Ultegra
The CS-R8100 from Shimano is the 12-speed cassette that corresponds to the new Ultegra R8100 groupset. The advanced transmission is 100% performance-oriented and is a true revolution thanks to HYPERGLIDE+ technology.
With great speed comes great responsibility. So, faced with the task of making the new ULTEGRA groupset even faster, Shimano has opted for a holistic and 100% performance-oriented approach. The new 12-speed road groupset offers unrivaled control and comfort anytime, anywhere, whether you're racing, chasing a personal best time, or cruising in company. It is the “Science of Speed”. And it is what differentiates SHIMANO from the rest.
The seamless shifting of ULTEGRA R8100 12-speed cassettes lets you climb, sprint or roll without having to think about the next gear change. The larger teeth maximize drivetrain efficiency, while being compatible with previous 11-speed freewheel bodies. The cassette is available in 11-30Z and 11-34Z.
HYPERGLIDE+ cassettes set new standards for off-road shifting thanks to fluid upshifts and downshifts across the entire gear range. It's about time this technology is also used on road bikes. It is now possible to change gears even when using maximum power on climbs or in a direct duel with an opponent. In all gears, the ULTEGRA R8150 transmission guarantees maximum efficiency thanks to larger teeth and ensures compatibility with existing HYPERGLIDE FREEHUB freewheel bodies. Despite being expanded to 12 gears, the ULTEGRA CS-R8100 cassettes set new standards in road bike shifting systems.
