Experience the smooth shifting of the ULTEGRA R8100 12-speed cassette range. Whether you're climbing, sprinting, or cruising, the seamless gear shifts allow you to focus on your ride. The larger driving cogs enhance drivetrain efficiency and are compatible with both Shimano 11 and 12-speed FREEHUB bodies.

Similar to how HYPERGLIDE+ cassettes revolutionized off-road shifting, they are now transforming road cycling. With seamless shifts up and down the gear range, riders can maintain maximum effort without needing to ease off to shift. The ULTEGRA R8150 drivetrains maximize efficiency in any gear, thanks to the larger cogs, while remaining compatible with existing HYPERGLIDE FREEHUB bodies. Featuring 12 gears, the ULTEGRA CS-R8100 cassettes set a new standard in road shifting.

Features:

• Refined 12 step gear combination provides peak efficiency and accelerating performance for every racing situation.
• Faster, smoother shifts under maximum pedaling force.
• Compatible with new 12-speed and road 11-speed FREEHUB body.
