Magura Gustav Pro Brakes Bigtime power. The Magura Gustav Pro Brakes take gravity and e-MTB braking to a whole new level. These high-powered stoppers are designed to handle the heaviest bikes, the most demanding braking, and the longest descents all without fading or overheating. The Gustav Pro Brakes feature enlarged, 12 & 19mm pistons to reduce overall system pressure resulting in a more defined pressure point and better brake modulation. The Gustav Pro Brakes are more than just powerful, they also require significantly less maintenance. The brakes use 2. 5 mm-thick brake rotors (sold separately), extra-thick brake pads with 94% more volume, and boast an Easy Link connection system and new Easy Bleed system for more time spent riding, and less time in the shop.
