Confident, all-weather stopping for your drop-bar road or gravel build. This is SRAM's Apex 1 HRD hydraulic brake set up as a front brake, pairing a brake-only left HydroR lever with a forged aluminium two-piston caliper for crisp, easy-to-modulate power straight from the hoods.

Highlights

  • Front brake assembly with a 950mm hydraulic hose
  • Brake-only left HydroR lever (no shift function) with tool-free reach adjust
  • Two-piston forged aluminium caliper running DOT 5.1 fluid
  • Steel-backed organic pads with steel hardware for quiet, controlled braking
  • Mounting hardware included; rotor and bracket sold separately

Smooth hydraulic control

SRAM's hydraulic road system delivers a consistent lever feel and strong, fade-resistant power. DOT 5.1 fluid carries a high boiling point for repeated hard braking on long descents, while the two-piston caliper and steel-backed organic pads keep modulation predictable and noise low.

Ergonomic lever

The lever body is shaped for a secure finger wrap from the hoods, and tool-free reach adjustment lets you dial in confident one-finger control to suit your hand size.

Compatibility and fit

Built on SRAM's Road ExactActuation 11-speed platform as a dedicated brake control, so this side does not shift. The caliper is designed around a 160mm rotor and converts to 140mm with the appropriate adapter bracket. The disc rotor and mounting bracket are not included and are sold separately. The 950mm hose length suits a front-brake routing on a typical drop-bar setup.

SRAM components are covered by SRAM's standard limited warranty against defects in materials and workmanship for two years from the original date of purchase. The warranty does not cover damage from crashes, improper installation, neglect, or normal wear (including brake pads and worn parts).

For any warranty claim or support, please return the item to Tune Cycles and our team will assess it and manage the process on your behalf.
