The Elevn Technologies "Post Mount 120" BMX Race Disc Brake Adapter Kit - Chase ACT converts a Chase ACT 1.0 or 1.2 frame to a post mount rear disc brake, mechanical or hydraulic. The adapter is CNC machined from 6061-T6 aluminum and is designed for a 120mm rotor, with a 20mm post mount riser a 140mm rotor fits too. The kit has everything for the conversion except the brake itself: adapter, 120mm rotor with ISO 6 bolt mount, chain tensioner with anti rotation, bolts, spacers and covers for the V-brake bosses. Choose the axle (10mm or 20mm) as an option.
The hub needs an ISO 6 bolt mount, with a Center Lock / ISO adapter a Center Lock hub works too.
