Lewis AX Brake System Set – Ultimate Braking Power, Evolved
Bigger Pistons. Better Control. Ultimate Confidence.
Meet the Lewis AX Brake System, a new-generation braking system built for riders who demand uncompromising performance on aggressive trails and technical descents.
The AX combines 18mm + 20mm large pistons, a one-piece caliper body, and advanced cooling fin design, delivering exceptional braking consistency even under extreme heat.
Key Features
4-Piston Power System (2×18mm + 2×20mm)
The newly developed asymmetric piston layout enhances brake modulation and power balance — providing smooth control in the early stroke and strong bite when you need it most.
7075-T6 CNC Machined Body
Precision-machined from aerospace-grade aluminum for maximum rigidity and reduced weight, ensuring a stable feel and longer lifespan under race conditions.
Titanium + Ceramic Insulated Pistons
High-performance pistons with titanium-ceramic composite insulation prevent heat transfer to the brake fluid, maintaining consistent performance on long descents.
Independent Cooling Fins
Integrated cooling fins dissipate heat efficiently, boosting temperature stability and preventing fade during prolonged braking.
Triple Adjustment System
Fine-tune your brake feel with Reach, Bite Point, and Free Stroke adjustments. Get your lever setup exactly how you want it — from light feathering to aggressive bite.
Anti-Oil Loss Connector
Removable olive fittings ensure a leak-free system and easy maintenance for long-term reliability.
Split Clamp Design
Simplifies installation and maintenance — no need to remove grips during setup.
