Brake Therapy is the original, and still the best option for converting any bike to disc brakes.

The unique design works on any bike, hardtail, full suspension, road, tandem, cruiser, cross, trials, or bmx.

It will work with any shape or type of dropout, conventional, horizontal or thru axle. Any type of disc brake can be used, mechanical or hydraulic, and any brand of disc brake is compatible.

The caliper mounting bracket is located on the hub via a special spacer, which is provided with the kit. This insures that the caliper is always centered perfectly on the disc. The rod attaches to the v-brake or canti boss, feeding the loads into the frame in a manner that is less stressful than with v-brakes,as it is inline with the seatstay, as opposed to a perpendicular load path with v-brakes.

Brake Therapy has been on the market since 1997, providing thousands of happy customers with the ability to update their favorite bike to disc brakes. Most popular magazines have reviewed and approved of Brake Therapy.  Here's some reviews Brake Therapy
