Rotor UNO hydraulic groupset first impressions

This article originally appeared on BikeRadar

BikeRadar was recently invited out to Madrid to test a few new components from Rotor, these included the company’s lightest ever crankset as well as its innovative Rvolver hubs.

We were also able to revisit Rotor’s hydraulically actuated groupset, the UNO — a long-awaited rarity that still holds the crown for the lightest disc-specific group.

Rotor Aldhu 3D+ chainset

 

The Aldhu 3D+ chainset uses no external bolts, making for an exceptionally clean look

Named to commemorate Rotor sponsored athlete Carlos Sastre‘s first victory at Alpe d’Huez during the 2008 Tour de France, the Aldhu 3D+ crankset uses direct-mount chainrings in a modular design that brings more adjustability and customisation than any Rotor crank before it. Rotor claims that it’s also the lightest crank to date from the company and — just like the rest — it’s 100 percent made in Madrid.
