## Summary description

Clarks disc brake adapter converts a Post Mount caliper to a Flat Mount frame or fork for rear installation with 180 mm rotor spacing. Manufactured for compatibility with post-mount calipers and flat-mount mounts, it provides correct alignment for disc rotors and calipers on road, gravel, and urban bikes requiring a 180 mm rear rotor.

## Long description

The Clarks disc brake adapter converts a Post Mount caliper to a Flat Mount frame or fork for rear installation with 180 mm rotor spacing. Designed for compatibility between post-mount calipers and flat-mount tabs, this adapter ensures correct caliper-to-rotor alignment for rear 180 mm rotors on road, gravel and urban bicycles. The adapter is intended for use where a rider needs to fit a larger 180 mm rotor to a flat-mount frame or fork while retaining a post-mount caliper.
Advantages
This adapter provides secure mechanical alignment for a rear 180 mm disc rotor without requiring modification to the frame or caliper. It allows installation of a post-mount caliper on flat-mount fittings, preserving brake function and rotor clearance. The component is compact and designed for straightforward fitting with standard hardware, helping maintain consistent braking performance and rotor centring when upgrading or replacing brake components.
Suitable for
 Bicycles with flat-mount rear mounts that require a 180 mm rotor
 Post-mount calipers being used on flat-mount frames or forks
 Road, gravel and urban bikes needing increased rear braking power or heat capacity
Key specifications
 Mount conversion: Post Mount caliper to Flat Mount interface
 Rear rotor spacing: 180 mm
 Orientation: rear-specific adapter design
 Material: engineered metal alloy suitable for brake mounting (manufacturer-specified alloy)
 Finish: corrosion-resistant surface treatment for outdoor cycling environments
How to use
Install the adapter between the frame or fork flat-mount tabs and the post-mount caliper using the appropriate bolts and torque values specified by the frame, caliper, and hardware manufacturers. Ensure the rotor is the correct 180 mm size and check pad clearance before final tightening. After installation, spin the wheel to confirm there is no rotor rub and perform a brake bed-in and adjustment procedure as recommended for the caliper to ensure proper braking response.
Usage recommendations
Confirm compatibility of bolt length and thread type with your frame and caliper prior to installation. Use correct torque settings and periodically inspect mounting bolts and adapter interface for tightness and corrosion, especially after extended wet or off-road use.
