Confident, consistent stopping for flat-bar road bikes. The SRAM S-300 is a hydraulic disc brake built around SRAM's DirectLink lever and a flat-mount caliper, delivering a solid lever feel and a predictable bite point so you can brake later and with more control. This is the rear caliper half-system with a right-hand lever and a longer 2000 mm hose to reach the rear of the frame.

Highlights

• Hydraulic disc brake for flat-bar road bikes
• Flat-mount caliper with 20 mm offset
• DirectLink lever for a solid, positive feel
• Stamped aluminium lever blade with tooled reach adjust
• Steel-backed organic brake pads fitted
• 2000 mm hydraulic hose suited to the rear caliper run

Smooth, repeatable power

SRAM's timing-port closure system pairs durable seals with an ultra-smooth cylinder bore for dependable power and a consistent bite point lap after lap. The DirectLink lever translates effort into braking force without vagueness, giving you precise modulation on descents and in traffic.

Set up to fit your hands

The stamped aluminium lever blade keeps weight down, while tooled reach adjustment lets you dial the blade closer for smaller hands or comfort. Steel-backed organic pads come installed, and the brake runs on DOT brake fluid.

Compatibility & fit

Designed for flat-mount road frames using a 20 mm caliper offset. Supplied as a complete lever-and-caliper assembly with hose and pads; the rotor is sold separately, so choose a SRAM-compatible disc rotor in your preferred size and mount standard. This right-hand lever is paired here with the rear caliper; on a typical Australian setup the right lever runs the front brake, so choose the lever side that matches your bike's plumbing.
