Brake rotor for e-bike Clarks CL-01 140 mm, IS mount (6-bolt), thickness 2.3 mm, silver

Clarks CL-01 is a 140 mm brake rotor engineered for e-bike use, with a 6-bolt IS (International Standard) mounting and a plate thickness of 2.3 mm. The silver steel construction provides a consistent braking surface for disc brake calipers and is intended for urban and commuting e-bikes where reliable stopping performance and compatibility with 140 mm IS hubs are essential.

Advantages

The rotor’s 140 mm diameter and 2.3 mm plate thickness deliver predictable heat absorption and stable contact with compatible calipers. The 6-bolt IS mounting ensures a secure fit on hubs designed for International Standard interfaces. Steel construction in a silver finish offers durability and predictable wear characteristics under normal urban riding conditions.

Suitable for

• Urban and commuter e-bikes with 140 mm disc brake systems
• Hubs and frames that accept 6-bolt IS (International Standard) rotors
• Riders seeking a replacement rotor for routine city use and moderate braking loads

When it may not be suitable

This rotor is sized and specified for light to moderate e-bike braking demands typical of urban and commuting scenarios. It may not provide sufficient thermal capacity or mechanical strength for heavy-duty, downhill, cargo, or high-speed performance e-bikes that require larger diameters, thicker rotors, or rotors specifically designed for high-power braking systems. It is also not intended for hubs that use center-lock mounting systems or non-IS standards.

Key specifications

• Rotor diameter: 140 mm
• Mounting pattern: 6-bolt, IS (International Standard) interface
• Plate thickness: 2.3 mm
• Material and finish: steel, silver
• Design purpose: disc brake rotor for e-bike urban/commuting use

How to use

Install the rotor onto a compatible hub using six appropriate bolts and an IS-compatible adapter or mounting surface, following the hub manufacturer’s torque specifications. Ensure the rotor is centered and true before tightening bolts evenly in a star pattern. After installation, check caliper alignment and pad clearance, and bed in new brake pads according to the pad manufacturer’s instructions to achieve consistent braking performance.

What to consider before purchase

• Confirm your hub and frame accept a 6-bolt IS rotor of 140 mm diameter
• Verify caliper compatibility with a 140 mm rotor and 2.3 mm thickness
• Consider braking demands—commuting versus high-power or downhill use
• Check whether hardware (bolts, spacers, adapters) is included or must be purchased separately

Usage recommendations

For reliable operation, use with pads and calipers rated for e-bike braking loads, inspect rotor runout periodically, and replace the rotor if signs of warping, deep scoring, or excessive wear appear. Follow manufacturer torque values for mounting bolts and perform a controlled bedding-in procedure after installation.
