## Summary description

Clarks rear IS 203 mm brake adapter designed to mount a disc brake caliper to International Standard (IS) rear frame or fork mounts. Compatible with 203 mm rotor size, this adapter facilitates correct alignment and secure attachment of the caliper for consistent braking performance. Intended for bicycles requiring rear IS-to-post mount conversion or rotor upgrade.

## Long description

The Clarks rear IS 203 mm brake adapter enables mounting a disc brake caliper to International Standard (IS) rear frame or fork mounts for use with a 203 mm rotor. It is designed to position the caliper at the correct offset when upgrading to a larger rotor or converting an IS mount to accept a post-style caliper attachment. The adapter provides a stable connection between the frame mount and the brake caliper to support consistent rear braking performance.
Advantages
The adapter is engineered to provide accurate caliper alignment for a 203 mm rotor, reducing the need for repeated manual adjustments. Its construction ensures a secure connection to IS mounts and maintains consistent spacing under braking load. The design minimizes interference with nearby frame or wheel components while allowing straightforward installation using standard mounting hardware.
Suitable for
 Rear bicycles requiring conversion from IS mount to accommodate a 203 mm rotor
 Upgrading rear rotor size to 203 mm for increased braking torque
 Replacing a damaged or missing rear disc brake adapter on frames with IS mounts
Key specifications
 Compatible rotor size: 203 mm
 Mount type: International Standard (IS) rear mount to post-style caliper offset
 Application: rear wheel disc brake mounting
 Material: metal alloy suitable for brake mounting (manufacturer specification)
 Finish: corrosion-resistant coating to suit outdoor bicycle use
How to use
Position the adapter on the frame's IS rear mount so the mounting face aligns with the caliper's bolt holes for a 203 mm rotor. Secure the adapter to the IS mount using the appropriate bolts and torque settings recommended by your caliper and frame manufacturers. Mount the caliper to the adapter and adjust lateral alignment so the pads are evenly spaced around the rotor, then tighten all fasteners to specified torques and check for rotor clearance through the full wheel rotation.
Usage recommendations
Verify compatibility with your frame and brake caliper before installation, and use correct torque values for all fasteners. After fitting, perform a controlled test ride and re-check bolt tightness and caliper alignment. Replace the adapter if signs of wear, deformation, or corrosion compromise safe mounting.
