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.
