CS-6700 Cassette Ultegra 11-28t 10s

The CS-6700 is a Shimano 10-speed Ultegra cassette, and delivers the smooth, precise shifting Ultegra is known for on any 10-speed Shimano-compatible drivetrain. HG sprocket geometry and carefully positioned shift ramps keep the chain tracking cleanly across gears, and at 229g it's a genuinely light option in this range.

This 11-28T spread (11-12-13-14-15-17-19-21-24-28) suits riders who spend most of their time on rolling terrain rather than steep sustained climbs, giving tighter jumps between gears than a wide-range cassette would.
