The U.P. (Unbeaten Path) family combine a road riding position with clearance for mountain bike tires. Get out of town on asphalt, hit the gravel roads or switch to singletrack. Your position gets you there fast; the big tires make you unstoppable.
The frame is available in two versions: Light (U.P.) and Super Light (U.P.P.E.R.).
Every U.P. and U.P.P.E.R. shares the same silhouette, geometry, fork and most importantly tire clearance. But they differ in their carbon weight and layup.
