U.P.P.E.R combines a road riding position with clearance for mountain bike tires. Get out of town on asphalt, hit the gravel roads or switch to single track. Your position gets you there fast; the big tires make you unstoppable.
The U.P. fits mountain bike tires up to 2.1” wide. But you can also fit a 40mm cross tire, or a 28mm road tire, or anything else in-between (exact tire sizes depend on manufacturing tolerances and rim width, so this is a guideline. Always make sure you have 6mm clearance between tire and frame).
How do we fit such a wide range of tires without affecting the handling? Let's start with the numbers; below is the outside radius for various wheel+tire combos:
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.
