Shimano SM-RT70 Disc Rotor - ISMRT70M

The Shimano SM-RT70 Disc Rotor has a sandwich structure of an aluminium core embedded in 2 stainless steel layersThe higher heat dissipation of the aluminium helps to reduce the surface temperature of the rotor by around 100 degrees Celsius.Optional Ice-Tech brake pads with aluminium cooling fins can reduce the brake pad surface temperature by another 50 degrees. The result is high stopping power and practically no signs of fading!They feature a new design with refined shaping over the RT68 rotor. An aluminium lockring is a further improvement over the older steel version making the package more light weight.Centrelock Disc not compatible with IS2000 disc rotor mount (6 hole system)The 180/203mm disc requires a special adapter. Please do not exceed the disc specifications of your fork/frame.FeaturesSM-RT70 Ice Tech rotors give excellent performance using the proven Shimano Centre-Lock system providing excellent rigidity and security with an easy set-upThe clad steel/alloy/steel rotor construction allows heat generated from braking to radiate quickly through the aluminium core achieving surface temperature drops of around 50 degrees C. When used with Ice Tech pads surface temperatures can drop from around 400 to 300 degrees C, this provides great improvements in performance all roundNew refined shaping design over RT68Ice Tech rotors achieve long pad life, less noise and less fade due to improved heat dispersionRotor contact surface has been developed for excellent pad clearing and cooling which increases pad performance and lifeComes complete with lockring
