SHIMANO XTR RT-MT900 CENTRE-LOCK DISC ROTOR WITH INTERNAL LOCKRING 203mm new_product Lever reach adjust: YesThe design of the Shimano XTR Dura Ace RT MT900 disc brake rotors is a further development of the successful ICE TECHNOLOGIES FREEZA design. While the further weight reduction of 5g and 10g is particularly attractive for the 140mm and 160mm discs, the 180mm and 203mm versions are characterised by a further improvement in heat dissipation of 20C in intensive tests and are also pleasantly low weight (203mm: minus 30g).
