SRAM Rival 1 Hydro R Disc Brake and Shift Lever OEM

Rival 1x was designed as a comprehensive solution to meet criteria for both road AND dirt 1x applications. Gravel grinder? Check. Dedicated roadie? No problem there! Hardcore cross racer on a budget? Yep. Jump in folks. Simplify, lighten, and improve not only your "rig", but the game you bring as well.

For those not familiar with SRAM's one-by offerings, SRAM brings heaps of technology to their one-by drivetrains. For the Rival 1 release, the lever ergonimics have been revised to deliver a much better finger wrap and the shifter paddle delivers improved finger clearance. Using what SRAM calls ErgoDynamics, this rear brake (which includes a shift paddle) has independent adjustments for both brake reach AND shift reach. Forged aluminum levers will deliver years of flawless and durable performance.

This lever, being hydraulic, is a fully-sealed system, which virtually eliminates contamination. Though this brake comes pre-bled, the designers also included an easy bleed access should the need arise to take care of business.

The result of all of this wizardry is a durable, nearly maintenance free shift/brake lever that requires very little hand force to use. Don't get left in the dust.

Lever Body - The SRAM HydroR lever body design has an improved internal architecture and material placement around the reservoir and master cylinder bore, which is all about improving consistency and performance.

Bleed Port - The bleed port design offers a simple interface for setting up and bleeding the brakes.

Master Cylinder - At the core of the MY15 hydraulic road brakes is a new master cylinder piston. With incredible amounts of testing behind it, it has improved performance and consistency, especially in extreme temperatures.

High Capacity Bladder - A higher capacity bladder is the primary fluid compensating device for pad wear.

Caliper Spring - The caliper spring is a small part that plays a big role. The HydroR spring spreads the pads more effectively and maintaining consistent rollback and contact point.

Shift Paddle - The MY15 HydroR paddle design has reduced material on the blade, lightening the shift lever and providing better finger clearance—a nice feature in colder cyclocross season temperatures when thicker gloves are required.
