Avid SRAM 20mm IS Disc Brake Adaptor Fits 180mm Front and 160mm Rear Rotors

AVID Adapter IS to PM +20 | black

The adapter enables the use of 180 mm (fork with IS 6" mount ) or 160 mm (rear triangle with IS 5" mount ) brake discs.

The adapter expands the brake disc by +20 mm. The IS2000 standard almost always uses the standard brake disc size of 160 mm (IS 6") on the fork. A standard brake disc size of 140 mm (IS 5") is almost always used on the rear end. Based on the standard brake disc size, the adapter increases the brake disc size by the specified information in millimeters.

Fork IS 6" = 160 mm standard size

Rear triangle IS 5" = 140 mm standard size
