SHIMANO | Shimano RT CL900 Ice Tech Brake Disc Center Lock Rotor for Road & Mountain Bikes 140mm/160mm Options Available

Shimano Dura-Ace RT-CL900 Ice-Tech Disc Brake RotorShimano has developed the RT-CL900 center lock brake disc specifically for the Dura-Ace BR-R9270 roadbike disc brake. Apart from that, it is also compatible with numerous brake calipers from the gravel or MTB segment. The brake disc is constructed in a sandwich composite with an aluminum layer between two stainless steel layers. Thanks to Ice-Technologies FREEZA and a special heat-dissipating coating, it does not overheat even on steep, long descents. In addition, the design has been optimized with regard to the lowest possible noise and the lowest possible weight. RT-CL900 comes with an internally toothed lock ring and can be used with both organic and sintered brake pads.Use: Road/MTBSeries:Dura-AceMaterial disc:Sandwich composite made of stainless steel outside with aluminium coreMaterial Spider:AluminiumDiameter:140mm, 160mmWeight:Approx 96g(140mm),114g(160mm)Brake compatibility:BR-M9100, BR-M9120, BR-M9110-R, BR-M9000, BR-M9020, BR-M8100, BR-M8120, BR-M8110-R, BR-M8000, BR-M8020, BR-M7120, BR-M7120, BR-M7110-R, BR-M7000, BR-M6100, BR-M6120, BR-M6000, BR-MT520, BR-MT420, BR-M820, BR-M640, BR-U8000, BR-U8020, BR-S7000, BR-S700, BR-R9270, BR-R9100, BR-R8170, BR BR-RX400Compatibility:For brake pads with narrow pad shapeLocking ring with internal toothing: compatible with 9/10mm quick release and 12mm through axleFor 15mm and 20mm through axle use SM-HB20 lock ring insteadFeatures:Ice-Technologies FREEZA and sandwich construction for even faster heat dissipationHeat-distributing coatingFirst-class, reliable braking performance on long, steep descentsSpecially designed for low noise and low weightTech:Ice-Tech FREEZAShimano Ice-Technologies ensure fast heat dissipation on your disc brake. The brake pads are equipped with cooling fins made of aluminium. The brake disc is constructed in a sandwich technique in which stainless steel encloses an aluminum core. The stainless steel on both sides ensures a long durability, the aluminum for heat dissipation. FREEZA is the further development of the brake disc, in which additional, specially coated ribs in the aluminum of the disc ensure an even better heat balance. This cooling technology ensures consistently high braking performance and longer brake pad durability while reducing fading and braking noise.
