C1 140mm Disc Brake Rotor - Center Lock, 1.9mm Thickness

The Promax C1 140mm Disc Brake Rotor delivers reliable braking performance for riders who want consistent stopping power on any ride. Built from durable stainless steel, this rotor is designed for long-term use and compatibility across a wide range of bikes—from mountain to commuter to e-bike setups.

Unlike many rotors in its class, the C1 works with both resin and metallic pad compounds, giving riders flexibility in tuning their braking performance without worrying about accelerated wear or compatibility issues. The 1.9mm thick SUS410 stainless steel braking surface balances strength, heat management, and corrosion resistance for dependable braking in all conditions.

A sturdy steel center spider helps maintain rotor stability under heavy braking loads, while the Center Lock design ensures secure and straightforward installation. Lockring is sold separately.
