Magura Gustav Rotor MDR-SMore rotor, more power. The Magura Gustav Rotor MDR-S is at the heart of the new Magura Gustav Pro Brake system, with a new thicker rotor design that pairs perfectly with the powerful Gustav Pro calipers, these rotors are up to the task of the fastest descents. The MDR-S rotor is designed for increased braking rigidity and improved wear life, with a 2. 5mm thickness that generates a more positive and powerful feel. The MDR-S is also designed to reduce vibration for quieter braking, while the increased rotor mass offers more stability during extended braking and high brake loads. Features New 2. 5mm rotor thickness for a more positive feel, and increased mass for more predictable braking during extended braking and under high brake loads Designed for Gustav Pro Brakes with an increased thickness that pairs perfectly with the powerful Gustav Pro system Designed to reduce vibration for less noise | Magura | Gustav Rotor Mdr-S Rotor Mdr-S, Gustav, 180Mm, 2. 5Mm, 6 Bolt
