Pro — Dimension Data’s Matt Brammeier rides this Cervelo S5, kitted out with Rotor’s prototype Uno hydraulic shift system and Magura hydraulic rim brakes. He’s one of three riders on the team currently using the system. By the end of the year, seven riders will be testing it. The rest are riding Shimano Dura-Ace Di2 drivetrains.

Pro — Rotor claims that its hydraulic Uno groupset is 350 grams lighter than Dura-Ace Di2, and will be about the same price. Photo: Caley Fretz | VeloNews.com

Pro — The Uno hoods are quite slender considering they house hydraulics for both brake and shift actuation. The single paddle works similar to SRAM’s Doubletap system, and a rider can select how many gears are changed in a single swing. Photo: Caley Fretz | VeloNews.com

Pro — The rear derailleur has a small knob (visible just under the Uno logo) that sets the derailleur for easy wheel removal. Photo: Caley Fretz | VeloNews.com

Pro — Brammeier uses Enve’s SES Aero handlebars, which flare from hood to drop by 2cm. Photo: Caley Fretz | VeloNews.com

Pro — A helpful, if cheeky reminder for Brammeier, who suffered a bad crash at the Tour of Utah. Photo: Caley Fretz | VeloNews.com

Pro — We still haven’t ridden Uno, but have played with it while stationary. The actuation is incredibly smooth. Photo: Caley Fretz | VeloNews.com

Pro — Hydraulic actuation is powerful, and so the Uno front shifting has the potential to be just as good as electronic systems. Photo: Caley Fretz | VeloNews.com

Pro — Brammeier rides a prototype Rotor 2Power power meter and round rings. Photo: Caley Fretz | VeloNews.com

Pro — The Uno shifters are compatible with either hydraulic disc or hydraulic rim brakes. There is no cable-actuated brake option. Photo: Caley Fretz | VeloNews.com
