The Magura MT4 post mount kit is described by the company as a powerful all-rounder for brake street and trail. Well, we like it even better for BMX racing. You barely touch the brakes in racing and with a simple and elegant design, this one piston disc brake is all you need for racing. Plus the lever can be located on either side, saving you the hassle of buying a "front" or "rear" kit from you know who.
Thanks to its Carbotecture® brake master, the MT4 has a low total weight of less than 230 grams.
