Features: For the SL Road Pro we dug deep into Shimano's treasure chest of components. Wheels are built around Deore hubs, while the transmission is provided by the reliable Sora groupset. We've not compromised on the brakes, either. A bike capable of moving fast must be capable of stopping quickly, too - that's why we selected Shimano's BR-M315 hydraulic brake system. And of course, the SL Road Pro has passed the stringent standards set by CUBE's own test collective.
