Introducing the all new billet disc brake conversion for the BIG Ripper from SE Bikes. These bikes have been out for 10 years and are hotter than ever. We have finally perfected a solution to the annoying stock brakes, a billet bolt on disc brake bracket. This bracket is CNC machined from 6061 aluminum in the USA, and designed to work with SE axle tensioners and almost all mechanical calipers on the market. This kit works with the Navigate mag wheels as well as the OEM SE Bikes wheel (must be using oem free wheel). For use with the OEM rear wheel, you must buy our billet thread on hub with 160mm disc.
