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.
