The XTR and Dura-Ace RT-MT900 Brake Rotor by Shimano – Optimised in every respect
The Shimano RT-MT900 brake rotor was designed and developed on the basis of the successful Ice Tech FREEZA rotors. In the 140 mm and 160 mm versions, which are aimed particularly at road bike and cross-country riders, a weight reduction of 5 and 10 g respectively has been achieved. The 180 mm and 203 mm versions, specially designed for Enduro riders, are characterised by further improved heat dissipation and are, of course, also weight-optimised.

Technology:
Ice Tech FREEZA
Shimano Ice Technologies provide a fast heat dissipation at your disc brake. The brake pads are equipped with aluminium cooling fins. The brake rotor is constructed using a sandwich technique in which stainless steel encloses an aluminium core. The stainless steel on both flanks ensures long durability, the aluminium allows heat dissipation. FREEZA is the further development of the brake rotor, in which additional ribs in the aluminium provide even better heat compensation. This cooling technology creates consistently high performance and longer brake pad durability while reducing fading and brake noise.

Los mejores discos y tienda muy profesionales
Schnelle Lieferung. Wie immer alles top!
très bon disque,
4 étoiles parce que dans les très fortes sollicitations en descente montagne, j’ai eu un disque qui a trop chauffé et s’est voilé, mais ce n’est pas pour cette raison que je ne rachète pas !

Hammer Bremsscheibe. Habe meine Sm RT99 am Gravel Bike gegen diese getauscht und bin nicht enttäuscht wurden. Sie ist super leicht und verzieht sich auch bei starken Brems- / Sprintmanövern nicht. Definitiv ihren Preis wert!

Unglaublich tolle Bremsscheibe! Fahre sie auf meinem Crosser, die Bremsleistung ist spürbar besser und effizienter.
Mit 108,9 g (160mm) ist sie auch sehr leicht (leichter als die Dura Ace) werde sie deshalb auch auf meinen Straßenrädern installieren. Klare Kaufempfehlung!
