Lewis LV-S2 Hydraulic Disc Brakes

Ultra-Light • Dual-Adjust • Race-Tuned Control

The all-new Lewis LV-S2 redefines what’s possible from a lightweight two-piston brake. Designed for XC, trail, and dirt-jump riders who want high-end feel without the premium price, the LV-S2 delivers exceptional power, modulation, and control in an ultra-compact CNC-machined package. Built from 7075-T6 aluminum and engineered with Lewis’s patented 2-in-1 dual adjustment system, it’s the perfect balance of performance, simplicity, and precision.

Lightweight Precision Meets Serious Power

Now just weighing 300 g per set (without hose and pads), the LV-S2 is one of the lightest fully hydraulic systems in its class—yet it hits far above its weight. The new 2-in-1 lever design provides independent reach and bite-point adjustment, allowing you to fine-tune your lever feel on the fly. Four sealed cartridge bearings inside each lever pivot deliver an ultra-smooth, consistent pull, while the axial master cylinder keeps your cockpit clean and low-profile.

Engineered Caliper Design

The LV-S2 caliper uses dual 21 mm stainless-steel pistons to generate powerful, predictable braking force. Through continuous testing and refinement, Lewis reduced piston height and increased inner wall thickness while trimming overall body mass—resulting in a caliper that’s lighter, stiffer, and stronger. The result is rock-solid braking feel and confidence even in high-stress, high-heat conditions.

Built to Perform, Built to Last

A Primary + Secondary port system simplifies bleeding and improves consistency over time. The Kevlar-reinforced hoses and mineral-oil fluid reduce maintenance while maintaining lever feel in all weather. From race day to weekend laps, the LV-S2 brings premium-grade performance to any lightweight build.
