The ROTOR UNO Electronic MTB INspider Carbon Groupset combines the best technology and engineering we’ve developed for MTB drivetrains. Our lightest full MTB groupset featuring power meter.

With our UNO Electronic MTB Groupset, you’ll experience the most precise and responsive shifting available. The derailleur, in combination with our app, allows you to customize your shifting with micron-level precision. And at just 453g, it’s currently the lightest electronic groupset for mountain bikes on the market.

At the heart of the system is the INspider MTB power meter, one of the most advanced and accurate power meters available for mountain biking. It delivers detailed metrics and KPIs — not only telling you how much power you're delivering, but also showing your left/right leg balance and where in the pedal stroke you’re applying the most torque. This lets you train and improve based on real data, not guesswork. And it weighs just 105g!

Last but not least, you’ll be riding with some of the lightest and stiffest crank arms ever made for MTB. The Kapic Carbon crank arms weigh under 265g in any size and feature our patented Twin Leg© Technology, which eliminates power loss caused by spindle twisting under load.

If you want the best of the best for your MTB, this is the groupset you’ve been looking for. Fully compatible with any 1x MTB drivetrain from 10 to 13 speeds, it gives you total freedom to upgrade or fine-tune your setup. Get off the road, get of the standard!
