A2Z Adaptor I.S to I.S 160/5mm to 180/5mm AD-486

AD-486 caliper adapter allows you to use a larger diameter rotor (20 - 25 mm larger) for increased braking power. Fits most disc brake systems. For example: If your original rotor diameter is 160 / 165 mm, by adding the AD-486 adapter to your fork (frame), you can now use a 180 -185 mm diameter rotor!
