203mm Disc Brake Rotor Stainless Steel Bike Disc Brake Rotor with 6 Bolts

Key Features

  • Diameter: 203mm
  • Material: Stainless steel alloy
  • Mounting Interface: 6-bolt
  • Opposite Bolt Hole Distance: 44mm
  • Construction: Precision cut for consistent braking surface
  • Ventilation: Open design for improved heat dissipation
  • Includes: One 203mm rotor and 6 mounting bolts

Replaces / Cross-Reference Part Numbers

  • Serves as a direct replacement for any standard 203mm, 6-bolt mount disc brake rotor.

Compatibility & Fitment

  • Fits bicycle hubs with a standard 6-bolt disc mount (44mm BCD).
  • For use on bicycle frames and forks equipped with mounts for 203mm disc brake calipers. An appropriate adapter may be required.
  • Compatible with a wide range of hydraulic and mechanical disc brake systems from brands such as Shimano, SRAM, Avid, Magura, Tektro, and Hayes.
  • Suitable for Mountain Bikes (MTB), Downhill (DH), Enduro, E-Bikes, and other bicycles requiring 203mm rotors.

When to Replace

  • Rotor thickness measures below the minimum recommended width (typically stamped on the rotor, e.g., 1.5mm).
  • Visible warping, significant grooving, or cracks are present on the braking surface.
  • Persistent brake pulsing or vibration that is not resolved by cleaning or pad adjustment.
  • The braking surface is heavily contaminated with oil or other chemicals that cannot be removed.

Installation Tips

  • Ensure the hub's mounting surface is completely clean and flat before installation.
  • Install and tighten the 6 bolts in a star pattern to ensure even torque distribution.
  • Tighten bolts to the torque specification recommended by the hub or brake manufacturer, typically 4-6 Nm.
  • Clean the braking surface of the new rotor with isopropyl alcohol to remove any protective oils from manufacturing.
  • Perform a bed-in procedure with new brake pads to achieve optimal braking performance and reduce noise.

FAQ

This rotor fits bikes that use the standard 6-bolt disc brake mounting pattern, including many road bikes, mountain bikes, MTB, and BMX models equipped with disc brake hubs. Compatibility depends on your hub mount style and brake system clearance, not just the bike category. Check that your wheel hub uses a 6-bolt rotor interface and that your frame, fork, and brake caliper are set up to safely use a 203mm rotor.
No. This is a 6-bolt rotor, so it is designed for hubs with six rotor mounting holes. Center Lock hubs require a different rotor style or a suitable adapter if your brake setup allows one.
Common signs include pulsing or vibration under braking, squealing that continues after pad replacement and proper cleaning, visible warping, heavy scoring, blue heat marks from overheating, or reduced braking performance. If the rotor is bent, worn below the manufacturer's minimum thickness, or contaminated beyond recovery, replacement is usually the best fix.
Confirm four things before installation: your hub must be 6-bolt, your fork or frame must allow a 203mm rotor, your brake caliper adapter must match the larger rotor size, and your brake pads should still be in good condition. It is also smart to inspect the caliper alignment and wheel trueness before fitting the new rotor.
Most installations require a Torx wrench or bit for the six rotor bolts, usually T25, plus a torque wrench for proper tightening. Clean gloves or a lint-free cloth are helpful to avoid contaminating the braking surface. If you are also changing rotor size, you may need the correct caliper adapter and the tools to reposition the brake caliper.
For someone familiar with bike brake work, replacing a 6-bolt rotor is usually a straightforward job that takes about 15 to 30 minutes per wheel. Extra time may be needed if you are also changing caliper adapters, aligning the caliper, or bedding in new brake pads.
Not always, but it is often recommended if the old pads are worn unevenly, glazed, contaminated, or were used on a badly damaged rotor. A fresh rotor paired with poor pads can lead to noise, weak braking, or uneven pad transfer. If reusing pads, inspect them carefully and bed the brakes in again after installation.
Typical causes include repeated overheating on long descents, improper wheel or caliper alignment, uneven bolt tightening, contamination from chain lube or cleaners, and normal wear from braking. A rotor can also feel warped when the real issue is a misaligned caliper or uneven pad deposits, so it helps to inspect the full brake system before replacing parts.
