It’s hard to argue with the improves power and all-weather performance that disc brakes bring to road cycling. Its a given in other cycling disciplines and we have already started to see some big names get important race victories aboard disc brake bikes. Shimano’s Ultegra SM-RT800 Disc Rotors feature Freeza technology to cope with the sustained braking and higher temps associated with road cycling. This centerlock rotor continues Shimano’s trickle-down technology from Dura Ace that further advances the Ultegra range.
