Shimano SM-RT81 Rotor with Lock Ring
The clad steel / alloy / steel rotor construction allows heat generated from braking to radiate quickly through the aluminum core achieving surface temperature drops of around 50 deg C. When used with Ice-Tec pads surface temperatures can drop from around 400 to 300 deg C, this provides great improvements in performance all round.
- Ice-Tec rotors achieve long pad life, less noise and less fade due to improved heat dispersion
- Centerlockring Mounting
- Rotor contact surface has been developed for excellent pad clearing and cooling which increases pad performance and life
- Large forged alloy spider supports rotor surface, increasing rigidity and reducing weight
- Weight: 142g No Lockring
