The GUSTAV PRO is the first disc brake ever to use 2.5 mm thick rotors and makes every other brake look like a toy! Thanks to its mass, the rotor heats up significantly slower, stays in the sweet spot longer and thus offers consistent performance in every position for a smooth, vibration free and noiseless ride. Designed for thru-axle type hubs and includes an external spline lock ring for mounting Offers high braking power and good heat resistance at a moderate weight The optimized friction ring design and the high rigidity ensure low-vibration and particularly quiet braking even under high loads 2.5 mm rotor thickness is only compatible with Magura Gustav and Clara brake calipers Constructed with Martensitic chrome steel with anti-rust properties 2.1mm wear limit Item Specifications Hub/Disc Compatibility Center-Lock Pad Compatibility Resin Pads Only Rotor Size (mm) 180 Rotor Type Two Piece Magura Gustav Pro MDR-S 2.5mm Disc Brake Rotor Disc Rotor EAN: 4055184043974
