The Shimano MT900 Rotor is a versatile and reliable addition to your groupset. It began as the top choice for XTR users but can also be used with XT and 12-speed Shimano Road groups. On a demanding ride on the trail or road, reliable disc brakes with powerful modulation are a necessity. This rotor boosts heat dissipation by 20 degrees Celsius with the help of a heat dissipating paint on exposed aluminum layers. The smaller rotors are designed for weight savings for cross-country performance. Larger models are also an option for difficult trail riding and aggressive endurance riding. These rotors use centerlock attachment and are compatible with Shimano calipers.
