An ideal choice for riders maintaining a Shimano 10-speed road drivetrain who want dependable shifting, a useful 11–28T range and durable everyday performance.
The Shimano CS-6700 Ultegra is a 10-speed road cassette designed for race and performance road cycling. Its 11–28T progression gives you close ratios through the faster gears while adding useful range for sustained climbs, making it a practical choice for maintaining an older 10-speed road bike or refreshing a worn drivetrain.
Shifting is handled by Shimano HyperGlide sprockets, with updated tooth profiles intended to deliver smoother, more precise gear changes. The cassette uses nickel-plated steel cogs for a durable working surface, while the three largest sprockets sit on a six-arm aluminium carrier and the lockring is made from aluminium.
With an approximate weight of 242 g, the CS-6700 balances performance and value without chasing the lowest possible gram count. It fits Shimano HG freehub bodies and is intended to pair with RD-6700 or RD-7900 rear derailleurs, so check your existing drivetrain before ordering. Customer feedback also consistently describes the cassette as a dependable, clean-shifting option for everyday riding and training use.
