## Summary description

Clarks 180mm Post Mount disc brake adapter for rear wheel installation. Designed to mount a 180 mm rotor to a Post Mount caliper on the rear of the bicycle, this adapter provides the correct offset and bolt pattern for compatible frames and calipers. Suitable for replacing or upgrading rear disc brake mounting to fit 180 mm rotors.

## Long description

Clarks 180mm Post Mount disc brake adapter for rear wheel installation is designed to allow fitting a 180 mm rotor to a Post Mount caliper on the rear of the bicycle. The adapter provides the correct offset and bolt pattern to align the caliper with a larger rotor, enabling reliable braking performance after upgrading or replacing the rear disc rotor size. Constructed to match common Post Mount standards, it is intended for use where frame and caliper compatibility require a spacer or adapter to achieve proper pad-to-rotor clearance.
Advantages
The adapter ensures accurate caliper alignment with a 180 mm rotor without the need to modify the frame or caliper, preserving factory mounting points. It simplifies upgrade or replacement procedures by offering a dedicated spacing solution for rear Post Mount setups. The design reduces the risk of rotor-pad contact by providing the correct offset and maintains consistent braking geometry for predictable stopping performance.
Suitable for
 Upgrading a rear brake to a 180 mm rotor on frames with Post Mount bosses
 Replacing a worn or damaged rear mount adapter to restore correct rotor alignment
 Installing aftermarket calipers that require specific offset for 180 mm rotors
Key specifications
 Rotor compatibility: 180 mm rear rotors
 Mount type: Post Mount rear adapter
 Function: Provides correct caliper offset for 180 mm rotor installation
 Application: Rear wheel bicycle disc brake systems
 Material: metal alloy suitable for brake mounting use
How to use
Secure the adapter to the bicycle's rear Post Mount bosses using the appropriate bolts and torque settings recommended by your frame and caliper manufacturers. Mount the caliper to the adapter and position the 180 mm rotor in the hub and wheel assembly. Align the caliper to achieve even pad clearance on both sides of the rotor, then tighten mounting bolts to specified torque. After installation, spin the wheel and check for rotor rub; if necessary, fine-tune caliper position or mounting hardware to eliminate contact.
Usage recommendations
Use compatible hardware and follow manufacturer torque specifications when installing the adapter. Verify frame and caliper compatibility with a Post Mount 180 mm adapter before fitting. After installation, perform a test ride and periodic inspections to ensure secure fastenings and correct rotor-to-pad alignment for safe braking performance.
