UNO Electronic Gravel Carbon Groupset

The ROTOR UNO Electronic Gravel Carbon Groupset is our lightest version among our complete groupsets for Gravel bikes. It has been designed for cyclists seeking the highest performance on their bike through its extreme lightness combined with optimal stiffness.

The key to this configuration lies in optimizing the weight thanks to high-performance components, such as the ALDHU Carbon crank arms. Manufactured with eight layers of high-module carbon fiber, they offer a weight of only 259g in their 170mm version.

Furthermore, our 1X Direct Mount chainrings are not only super light, being manufactured from 7075 T6 aluminum, but are also extremely rigid since they do not require a spider and additional bolts. Thus, they minimize power loss due to flex.

Finally, our UNO Electronic shifting group offers an ultra-fast response of only 150 ms per shift. Backed by a 600 mAh battery with leading autonomy and a weight of only 1165g (derailleur, shifters, and brakes). All without giving up the versatility of ROTOR's characteristic modularity. This will allow you to change these crank arms for aluminum ones, another cassette, or mount a power meter at any time without restrictions.

The ROTOR UNO Electronic Gravel Carbon Groupset offers a definitive balance between featherlight weight, durability, and electronic shifting precision, setting a new performance standard for your gravel routes.
