Uberbike Flatmount Adapter - +40mm 180mm Front

The Uberbike Flatmount Disc Brake Adapter allows you to change your rotor size and improve braking performance on your flatmount fork setup.

This adapter enables the use of a 180mm disc brake rotor with a flatmount caliper and flatmount fork. It adds +40mm, making it compatible with flatmount forks designed for 140mm native mounts when running a 180mm rotor.

⚠️ Note: If your fork uses a 160mm native mount, and you want to run a 180mm rotor, you’ll need our alternative adapter available here.

Key Features:

• Fits flatmount fork and caliper setups for 180mm rotors

• Adds +40mm (for forks with 140mm native mount)

• Precision CNC-machined from 6061-T6 alloy

• Laser-etched Uberbike logos for a premium finish

• Includes 2 x mounting bolts
