SHIMANO RT-CL800 CENTER LOCK Disc Brake Rotor ICE TECHNOLOGIES FREEZA 140MM 160MM 180MM 203MM for Road MTB Mountain Bike Parts

Shimano Ultegra RT-CL800 Ice-Tech Disc Brake RotorShimano developed the RT-CL800 Center Lock brake disc specifically for the Ultegra BR-R8170 roadbike disc brake. It is also very suitable for GRX gravel brakes. Apart from that, it is also compatible with numerous brake calipers from the 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, it provides excellent heat dissipation, even on steep, long descents. In addition, the design has been optimized with regard to the lowest possible noise and the lowest possible weight.Use:Road/MTBSeries:UltegraMaterial disc:Sandwich composite made of stainless steel outside with aluminium coreMaterial Spider:AluminiumSize:140 mm, 160 mmWeight:Approx 96g(140mm),114g(160mm)Brake compatible:BR-M9100, BR-M9120, BR-M9110-R, BR-M9000, BR-M9020, BR-M8100, BR-M8120, BR-M8110-R, BR-M8000, BR-M8020, BR-M7100, 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-R9170, BR-R8170, BR-R8070, BR-R7170, BR-R7070, BR-4770, BR-RS805, BR-R785, BR-RS785, BR-RS505, BR-RS405, BR-RX820-LE, BR-RX810, BR-RX400Compatible: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 dissipationFirst-class, reliable braking performance on long, steep descentsSpecially designed for low noise and low weightLocking ring made of aluminium, anodized (internal toothing)Tech: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.
