Classic U.P. vs New U.P. vs U.P.P.E.R.

The 3 members of the U.P. (Unbeaten Path) family all 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 three versions:

- The Classic U.P. with 3T Luteus II fork and post-mount disc brakes
- The New U.P. with OPEN U-Turn fork and flat-mount disc brakes
- The superlight U.P.P.E.R. with OPEN U-turn fork and flat-mount disc brakes

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 colour.
