4-piston caliper, strongest power, designed for Downhill and Enduro. 

Patented 2 in 1 dual adjustment for lever reach & bite point.

Front+Rear Brakes weight = 597g(Oil Hose included), 380g if without Oil Hose.

14mm+17mm 4 Stainless steel pistons with Metallic Pads.

Upgraded hinged clamp, no fray bike handlebar.

Easy Bleeding Technology.

Mineral Oil and Kevlar hose.

High-precision CNC machining technology.

Powerful but predictable braking force.  

Ultra-light lever action.

Bearing pivots provide superior modulation and feel.

Lewis' patented technology for dual adjustment of lever reach & bite point allows you to customize the feel to your preference for superior performance out on the trails.

Reach(tool-free), bite point(with allen key).

CNC 7075 T6 Aluminum four-piston caliper

7075 aluminum alloy allows for better rigidity increasing the overall performance of the brakes while keeping the power stable and predictable.

Four-piston caliper provides superior braking power for any situation on the trails. 

Increased lever blade length by 6mm for a more aggressive leverage ratio. With the dual adjustment system, you get stronger braking power without sacrificing reach.

14mm+17mm asymmetric piston design

The 14mm+17mm asymmetric piston design improves the linear feel of the brakes, balances the pressure distribution of the pads, and balances wear.

Four precision bearings

Four precision bearings constitute the pivot point of the lever blades.

Each movable pivot is composed of precision bearings on both sides providing a stable and smooth action.

Hose Material

1. PVDF and Teflon

2. Spiral filament winding

3. Kevlar bulletproof fiber braided layer

4. Tensile and corrosion-resistant ca

Hose customisation
