Shimano 11 Spd Ultegra 6800 Cassette 12-25 -
Shimano Ultegra 6800 11 Speed Cassette
Rider tuned wider gearing options with 11-speed
It's not often a cassette is the most significant component in the release of a new groupset, but the extra sprocket on this new Ultegra cassette will be a welcome addition for riders seeking wider ratios. The CS-6800 offers a broad choice which Shimano calls a 'rider tuned drivetrain', offering ratios they believe are appropriate to cycling's four major riding types.
The new 11-speed drive allows each cyclist to "tune" the bike for each specific application by various gradations. While its possible to achieve broad ratios from 10-speed set-ups, doing so from 11 speeds should reduce the gap between each sprocket. - Weight: 212g (11-23)
Can be used with Shimano 5800, and 9000 groupsets also.
