Uno Hydraulic Rim Shift/Brake Kit
While cable actuated and electronic drivetrains are quite the norm, Rotor decided to do things a little differently with its Uno Hydraulic Rim Shift/Brake Kit. This fully hydraulic groupset adds impressive smoothness to your shifting, and more powerful braking with better modulation as you train and race, all at the lightest weight possible from any current road groupset.
Much like your training regimen, Rotor aims to define its performance through differentiating its self from the others, which is what led to the development of the first hydraulic groupset. Integrating hydraulic technology from disc brakes into the drivetrain, Rotor's engineers were able to craft shifters that give you the power of efficiency and tactile command, with a smoothness that was previously never seen in shifters. Hydraulics don't only lend themselves to smoothness though, they also have the ability to reduce maintenance, with no cable stretch over time or pressure, and only one bleed necessary every year, which can be easily performed with the two included kits.
Shifting on the UNO should feel buttery smooth, but may take a moment to get used to as Rotor situates all indexing in the derailleurs, instead of shifters. Shifting is done with a double-tap style actuation, and is capable of shifting a full 4 gears at a time. Since your shift doesn't involve cable pull it won't give the same feedback that a mechanical system gives you, instead feeling buttery smooth, with no drag as it shifts positively through the cassette in a quick and decisive manner. Defined indexing helps with the feel when you need to shift under load, keeping things precise and reducing the possibility of missed, or accidental half-shifts. The rear derailleur also features an easy-access switch that drops you to the lowest sprocket that enables quick and easy wheel swaps.
It's no surprise with Rotor that details aren't taken lightly, so they've engineered a comically light cassette to go along with the groupset. With incredibly meticulous machining, the UNO Cassette features steel smaller cogs that are machined as one piece together, shaving off internal material, and runs with two large aluminum cogs. This enables the cassette to weigh in at just 149-grams for the 11 - 28t model — lighter than any cassette from the Big Three road component manufacturers, and boost its compatibility to run on 10-speed Shimano freehubs that may have had issues fitting a whopping 11-speed cassette previously. The cassette is shaped, milled, and polished at Rotor's Spanish headquarters, and treated with a friction-reducing finish before making its way into this groupset.
Taking braking seriously, the Spanish engineers at Rotor decided to pair up with Magura's German ingenuity to find ideal modulation and power. Magura's years of experience shine through with its RT8 rim calipers used with UNO, providing reliability and stopping power that you can trust. Compared to conventional rim brakes, these stoppers feature more precise braking control thanks to hydraulics, a frictionless, dirt resistant design, and easy maintenance while maintaining a quick release for fast wheel changes. Keeping things simple, Rotor not only uses Magura's Royal Blood for the braking system, but for the shifting system as well, making it easier to keep things bled and running flawlessly, without the need to purchase obscure additional fluids for the system.
