140mm Disc Brake Rotor Stainless Steel Bike Disc Brake Rotor with 6 Bolts

Key Features

  • Diameter: 140mm
  • Material: Stainless steel
  • Mounting Interface: Standard 6-bolt ISO
  • Bolt Pattern Diameter: 44mm
  • Thickness: 1.9mm
  • Design features rounded outer edges for safety
  • Surface is ground for flatness to improve braking consistency
  • Package includes one 140mm rotor and six mounting bolts

Replaces / Cross-Reference Part Numbers

  • Serves as a direct replacement for any standard 140mm rotor with a 6-bolt ISO hub interface.

Compatibility & Fitment

  • Fits bicycle hubs with a standard 6-bolt disc mount pattern.
  • Suitable for use on road bikes, mountain bikes (MTB), and BMX bikes equipped with disc brakes.
  • Requires a disc brake caliper and frame/fork mounting bracket compatible with 140mm rotors.

When to Replace

  • Rotor surface is worn below the manufacturer's minimum thickness specification.
  • Visible signs of damage, such as warping, deep grooves, or cracks.
  • Persistent braking vibration or pulsing that is not resolved by other adjustments.
  • Braking performance is significantly reduced.

Installation Tips

  • Clean the rotor and hub mounting surface with isopropyl alcohol before installation to remove contaminants.
  • Install the rotor following any directional arrows indicating the direction of wheel rotation.
  • Tighten the mounting bolts sequentially in a star pattern to the torque specified by the hub or bicycle manufacturer.
  • Ensure the brake caliper is correctly aligned with the new rotor to prevent rubbing.
  • Install new brake pads when replacing a rotor to ensure proper bedding-in and optimal performance.

FAQ

This rotor is compatible with bikes that utilize a 140mm, 6-bolt disc brake mounting system. This includes a wide range of road bikes, mountain bikes, MTB setups, and BMX bikes designed for disc brakes. The primary fitment requirement is that your wheel hub must accept a 6-bolt rotor, and your frame, fork, and brake caliper must be configured for a 140mm rotor.
Verify three criteria before ordering: 1) your current rotor size is 140mm, 2) your hub uses the 6-bolt rotor pattern rather than center lock, and 3) your caliper adapter and frame/fork are configured for a 140mm rotor. If your bike currently uses a larger rotor, such as 160mm or 180mm, you may need a different caliper adapter or a different rotor size.
Yes, a 140mm 6-bolt rotor is compatible with both mechanical and hydraulic disc brake systems, provided the caliper is designed to operate with a rotor of this size and type. The most important factor is matching the rotor size and mount style to your existing brake system.
Typical signs include pulsing or vibration during braking, excessive noise that persists after pad alignment, visible warping, scoring or heavy wear on the braking surface, and reduced braking performance even after installing new pads. Rotor replacement is also recommended if the rotor has been overheated or contaminated and cleaning fails to restore normal braking performance.
Installation typically requires a Torx driver (commonly a T25) and a torque wrench to ensure proper tightening. The process usually takes 10 to 20 minutes per wheel. Bolts should be tightened evenly in a star pattern according to the torque specifications recommended for your hub or rotor hardware.
It is highly recommended to inspect your brake pads during rotor replacement. If the old pads are heavily worn, glazed, contaminated, or were previously used on a damaged rotor, replacing them will significantly improve the performance of the new rotor. After installation, ensure the brake system is properly bedded in so the pads and rotor can mate correctly.
Common causes include overheating from prolonged braking, uneven bolt tightening, contamination from chain lube or cleaning agents, normal wear, and impact damage from transport or crashes. Brake rub can also occur if the caliper is misaligned or if the wheel is not seated correctly in the dropouts or axle mounts.
