Brake rotor for e-bike Clarks CL-01 160mm IS 6-bolt, thickness 2.3mm, silver

Clarks CL-01 is a 160 mm brake rotor made for e-bikes with an IS 6-bolt mounting interface. Constructed from stainless steel with a silver finish and a specified thickness of 2.3 mm, this rotor provides a stable braking surface and improved heat dissipation compared with thinner rotors. It is intended for use on hydraulic and mechanical disc brake systems found on urban, trekking and commuter electric bicycles as a replacement or upgrade part.

Advantages

The stainless-steel construction and 2.3 mm thickness offer a balance between strength and thermal mass, helping to resist warping under repeated braking and manage heat generated during prolonged runs on assisted bikes. The 160 mm diameter is a common size that combines effective braking torque with compatibility across many e-bike frames and forks that accept IS 6-bolt rotors. The silver finish gives corrosion resistance while maintaining a predictable friction interface with brake pads.

Suitable for

• E-bikes with IS 6-bolt disc brake mounts and 160 mm rotor clearance
• Hydraulic and mechanical disc brake systems on urban and commuter electric bicycles
• Replacement of worn or damaged 160 mm rotors on trekking e-bikes

When it may not be suitable

This rotor may not be suitable for frames or forks that require center-lock mounting or different bolt patterns. It is not compatible with rotor sizes other than 160 mm; using it where a larger or smaller rotor is specified can change braking performance and lever feel. For very heavy cargo e-bikes or steep mountain descents, riders may prefer larger diameter rotors or rotors with additional cooling features designed for intensive downhill use.

Key specifications

• Diameter: 160 mm
• Mounting: IS 6-bolt
• Material: stainless steel
• Thickness: 2.3 mm
• Finish: silver

How to use

Install the rotor on a compatible IS 6-bolt hub or adapter following the e-bike manufacturer's torque recommendations for the mounting bolts. Ensure the rotor is centered in the caliper and that rotor runout is within manufacturer tolerance; adjust caliper position or use shims if necessary. After installation, bed in the rotor and brake pads by performing a series of controlled stops at low speed to transfer a thin, even layer of pad material to the rotor surface. Periodically inspect the rotor for wear, scoring, or warping and replace it if thickness falls below safe limits or if braking performance degrades.

What to consider before purchase

• Confirm your e-bike uses IS 6-bolt mounting and has clearance for a 160 mm rotor
• Check compatibility with your brake caliper and adapter requirements
• Consider rotor thickness and material relative to your riding style and load

Usage recommendations

Use this Clarks CL-01 160 mm rotor with brake pads recommended for stainless-steel rotors and bed in the pads after installation. Regularly check mounting bolts for correct torque and inspect the rotor for signs of overheating or uneven wear; replace if deformation or significant thinning is detected.
