Is Rotor's Long-Awaited Wireless MTB Groupset Worth the Hype?

"Rotor is making a big return to the drivetrain market with its first new groupset in 10 years. Known for pushing boundaries and trying the unconventional, Rotor's last release was a hydraulically actuated 13-speed groupset that felt ahead of its time but struggled to gain traction. Now, the brand is back with a modern upgrade: a fully wireless 13-speed MTB groupset that eliminates hydraulic hoses for a cleaner setup and easier maintenance."

"This new UNO groupset is available in two flavors, much like the previous UNO Hydraulic groupset: one for gravel and drop-bar bikes, and one for mountain bikes. Both are designed around the same derailleur structure, but with different cage lengths to better suit different gear ranges. We're most interested in the MTB drivetrain, so let's dive into it. The wireless UNO MTB drivetrain comes as a kit that includes the shifter and rear derailleur."

"While the aesthetics may resemble those of the Wheeltop drivetrain components, the Rotor UNO systems are distinctly more premium, utilizing 7075 aluminum to enhance stiffness and performance. They are designed to work in conjunction with Rotor's existing cranksets, cassettes, and chainrings, allowing the derailleur to be customized to work with modern 12-speed cassettes and Rotor's own 13-speed cassettes. Outside of these cassette options, you can also use the app a"

Rotor returns to the drivetrain market with a fully wireless UNO 13-speed MTB groupset that removes hydraulic hoses for a cleaner setup and easier maintenance. The UNO family includes gravel/drop-bar and mountain-bike variants built on a common derailleur architecture with differing cage lengths for varied gear ranges. The wireless MTB kit ships with a shifter and rear derailleur and carries an MSRP of $800.43 USD. The system weighs 453 grams, supports 10–13 speeds, and uses a 600mAh battery rated for about 15,000 shifts. The drivetrain uses 7075 aluminum and is compatible with Rotor cranksets, cassettes, and chainrings.
