Shimano Ultegra CS-6700 10-speed cassette, 11-28T

An Ultegra-level 10-speed cassette that pairs close ratios through the middle of the block with a 28T sprocket for climbing. The aluminium sprocket carrier keeps weight down while holding the largest sprockets rigidly in place for clean, repeatable shifts.

Highlights

• 11-28T range: race-close steps low down, a climbing gear at the top
• Aluminium sprocket carrier and alloy lock ring to reduce shifting stress
• Robust shifting tolerance for consistent performance as the drivetrain ages
• Updated sprocket tooth design for accurate shifting

Gear progression

Ten sprockets: 11-12-13-14-15-17-19-21-24-28T. Single-tooth jumps from 11T to 15T hold your cadence at speed, then the steps open out to give you the 28T when the road tilts up.

Compatibility and fit

Suits Shimano 10-speed road drivetrains and mounts on a Shimano Hyperglide freehub body. Check your rear derailleur is rated for a 28T low sprocket. Replace a worn chain at the same time so the new sprockets are not dragged down by an old one.
