Product information

Description

Clarks 203 mm Post Mount rear disc brake adapter (model CLA-CB-R203PM) allows installation of a 203 mm rotor on bicycles with post mount rear caliper mounts. Designed to shift the caliper outward to align with a larger rotor, this adapter provides the correct spacing and orientation for safe and reliable braking when upgrading rotor size or modifying brake setup. It is made to work with standard post mount frames and common mounting hardware, enabling a straightforward upgrade path to a larger rear disc rotor without changing the caliper or frame.

Advantages

This adapter simplifies upgrading the rear braking system to a 203 mm rotor by providing precise caliper positioning in post mount frames. It reduces the need for additional custom hardware and minimizes adjustments during installation. The part supports consistent rotor-to-caliper clearance, helping maintain braking performance and reducing the risk of rotor rub. Its compatibility with common mounting bolts and typical rear frame layouts makes it a practical choice for many bicycle models.

Suitable for

  • Upgrading a rear wheel to a 203 mm disc rotor
  • Adjusting caliper position for larger rear rotors on post mount frames
  • Retrofitting bikes with standard post mount mounts to accept 203 mm rotors
  • Workshops performing brake upgrades or alignment corrections

Key specifications

  • Mount type: Post mount (rear application)
  • Compatible rotor size: 203 mm (rear)
  • Function: Caliper offset adapter to correct rotor alignment
  • Material: Metal alloy suitable for brake mounting applications
  • Installation: Uses standard post mount mounting bolts (not included)

How to use

Mount the adapter between the frame's post mount bosses and the brake caliper, orienting it according to the manufacturer's alignment marks or the caliper's required offset. Secure the adapter with appropriate post mount bolts, then attach the caliper to the adapter and torque fasteners to the bicycle and component manufacturer's recommended values. After installation, center the caliper over the 203 mm rotor and check for even pad contact and absence of rubbing by spinning the wheel and applying the brake several times.

Usage recommendations

Verify frame clearance for a 203 mm rear rotor before installation and use bolts of the correct length and grade for secure mounting. After fitting, perform a complete brake check including pad alignment, rotor trueness, and torque values. If unsure about installation or compatibility, consult a qualified bike mechanic.
