Lewis LH4 4 Piston Hydraulic Bicycle Disc Brake Kit
Purpose-built for aggressive trail, enduro and DH bikes, the Lewis LH4 four-piston brake kit packs big power into a lightweight, CNC-machined package.
- Asymmetric pistons (14 mm / 17 mm) balance power and modulation for precise control
- 7075-T6 aluminum caliper: high stiffness with minimal mass
- Split-clamp lever with dual tool-free adjustments (reach + bite point) for a perfectly dialled feel
- Kevlar-reinforced hoses and mineral oil resist heat, leaks and kinks
- Internal precision bearings ensure ultra-smooth lever action
- Independent cooling fins shed heat to fight fade on long descents
- Finishes: Black, Silver, Purple or Nebula to match any build
Reliable, tunable and built to last—the LH4 lets you brake later, ride faster and stay in command on the steepest terrain.
