The Unbeaten Path.
The New U.P. retains the performance-oriented road geometry & parts with clearance for mountain bike tires from the original. Start on asphalt, hit the gravel, switch to single track. Its geometry makes you fast; its tires unstoppable. The New U.P. accepts flat-mount brakes and ships with an OPEN U-turn fork.
Every U.P. and U.P.P.E.R. shares the same shape, geometry, intended use and most importantly: tire clearance. But they differ in layup, weight, fork, disc brake mounts, thru-axles and color.
