Heat management
Heavy-duty rotors
2.3 mm stainless-steel rotors engineered to hold a stable braking surface under sustained gravity loads.

Every component changes the feel.
Rotors, pads and adapters designed to make Lewis power repeatable—from the first braking point to the last.
System components
Tune heat, bite and fit.
The brake is only one part of the system. Match the contact surface, compound and mounting geometry to the bike.
Brake feel
Pad compounds
Choose predictable sintered power or quieter semi-metallic modulation to match terrain, weather and system load.

Fitment
CNC adapters
High-strength machined adapters align the caliper precisely across rotor sizes and frame mounting standards.
Post-mount fitmentsView componentCompatibility guide
Start with rotor size.
Frame, fork and caliper limits still apply. Confirm fitment with a Lewis dealer before installation.
