Brake rotor Clarks CFR-06 160 mm, floating design, aluminum spider, IS mount, silver-black

Clarks CFR-06 160 mm is a two-piece floating brake rotor designed for bicycle disc brake systems. The rotor pairs a steel braking track with an aluminum spider (carrier) to combine wear resistance at the pad contact surface with improved heat dissipation from the carrier. Its floating design allows limited movement between braking track and carrier to reduce the risk of warping and to maintain consistent braking performance under varying loads. The rotor mounts to calipers using the IS (International Standard) mounting interface and is finished in a silver braking track with a black aluminum spider for a neutral, durable appearance.

Advantages

The two-piece floating construction separates the steel braking surface from the aluminum carrier, which helps manage thermal expansion and reduces distortion during prolonged or heavy braking. The use of an aluminum spider lowers overall mass compared with full-steel rotors while keeping the steel track where durability and friction are required. The IS mount ensures compatibility with frames and forks that use the International Standard interface, and the rotor's 160 mm diameter provides a balance between modulation and stopping power suitable for many riding conditions.

Suitable for

• Mountain bikes used on cross-country and trail rides
• Urban and commuter bicycles requiring reliable, consistent braking
• Riders who prefer a lightweight rotor with good heat management
• Disc brake systems specified for 160 mm rotors and IS mounting

Key specifications

• Rotor diameter: 160 mm
• Construction: two-piece floating rotor (steel braking track + aluminum spider)
• Mount type: IS (International Standard) caliper interface
• Surface finish: silver braking track with black aluminum carrier
• Primary materials: stainless steel braking surface and aluminum carrier

How to use

Install the rotor to the hub or adapter following the IS mounting procedure appropriate for your hub or frame. Ensure the rotor is torqued to the manufacturer's recommended values for IS fittings and that all fasteners are secure. Check rotor alignment and caliper position to avoid pad rub; adjust caliper centering if necessary. Bed in new brake pads and rotor by performing a series of controlled stops from moderate speed to establish consistent friction and to remove surface contaminants. Periodically inspect the braking surface for wear, scoring, or heat damage and ensure the carrier fasteners remain tight.

Usage recommendations

Use brake pads compatible with steel rotors and follow a regular maintenance schedule: clean the braking surface with isopropyl alcohol or a manufacturer-approved cleaner, avoid oil and grease contamination, and replace the rotor when thickness or structural damage exceeds safe limits.
