Highlights

Why we rate it

Built for flared bars

Hood angle and shape are optimised for flared gravel handlebars.

Secure grip

Raised hood peaks, a ribbed hood texture and an anti-slip blade coating keep hands planted on rough ground.

Front Shift Next

Shimano's Front Shift Next option lets one button handle front shifts so you can shift without thinking.

Satellite ready

Works with all three SW-RS801 satellite switches for extra shift points on the tops, drops or aero bar.

Servo Wave braking

Fast pad engagement and controllable power for long descents on loose surfaces.
