The Shimano XTR RT-MT900 brake rotor with externally toothed lockring


This RT-MT900 Center-Lock brake rotor by Shimano comes with a lockring that has a new type of external toothing. Based on the successful Ice Tech FREEZA rotors, the model has been revised and further developed, both in terms of heat dissipation and weight reduction. The 180 mm or 203 mm diameter versions are aimed specifically at enduro riders, while the 160 mm brake rotor is suitable for cross country racing.

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.

Fahre die XTR MT-900 (203mm) in verbindung mit der XT 8120 4 Kolben Bremsanlage. Ich bin super zufrieden mit der Scheibe. Sie sieht am Bike einfach hammer aus, ist super leicht und tut was sie soll und das ist verzögern.

Da es eine Sandwitch scheibe ist und sie aus 2 verschiedenen Materialien besteht (Alu,Stahl) verzieht sie sich bei Hitze und neigt dazu zu schleifen und Geräusche zu machen. Nach ein paar Sekunden Erholung und leichten bremsungen legt sich dies auch schnell wieder, solltet ihr aber Wissen.

Wer Maximale Standfestigkeit sucht und auch vielleicht nicht der leichteste Fahrer ist, sollte eventuell zu Schweren und dickeren Magura MDR-P Scheibe Greifen.
Auch diese funktioniert mit der Shimano- XT Bremse, sieht aber meiner Meinung nach nicht so klasse aus.

Trotzdem vergebe ich volle Punktzahl da die XTR MT-900 volle daseins Berechtigung hat !

Scheibe leider nicht bei BC gekauft da ausverkauft.
