ICE TECHNOLOGIES FREEZA
The Shimano RT-MT900 is a 140 mm CENTER LOCK disc brake rotor built for consistent braking when your rides include long, steep descents. Its three-layer stainless steel–aluminium–stainless steel sandwich structure helps limit heat build-up, while the exposed aluminium radiator fin provides additional cooling during demanding braking.
The optimised 3D-shaped aluminium carrier helps resist heat distortion, supporting reliable rotor alignment and helping reduce rubbing noise as the rotor heats up. A more robust arm shape is also designed to improve quiet operation, making this a practical choice when you want strong braking performance without unnecessary brake noise.
Installation is simple if your wheel hub uses the CENTER LOCK spline interface: the rotor fixes securely with a compatible lock ring and can be removed without dealing with individual rotor bolts. Choose this rotor when your bike is already set up for CENTER LOCK and you want Shimano’s advanced heat-management construction in a compact 140 mm size.
A good choice for road, gravel and cross-country riders with a compatible CENTER LOCK hub who want consistent braking and improved heat control in a 140 mm rotor.
