Shimano SLX SM-RT68 180 mm Center Lock Disc Brake Rotor
Like the SM-RT81, the SM-RT68 Ice-Tech rotors have a sandwich structure of an aluminum core embedded in 2 stainless steel layers. The higher heat dissipation of the aluminum helps to reduce the surface temperature of the rotor by around 100 degrees Celsius. Optional Ice-Tech brake pads with aluminum 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!
Centerlock 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.
Weight: approx. 175 gram (180mm without lockring, approx. 190g with lockring)
