The first U.P. combined road bike speed plus go-anywhere capabilities to start a whole new category. Now original U.P. features such as dual wheel size compatibility and a dropped chainstay are the standard for performance gravel bikes.

-With road tires, it is a very fast road bike
-With big road/cross/gravel tires (32-40mm), it’s a go-anywhere bike perfect for mixed surface rides and most gravel routes
-With 650b mountain bike tires, it's unstoppable on very tough terrain yet much faster on pavement than you'd expect thanks to the road position

So the position lets you get out of town and reach the gravel/dirt/trails quickly (unlike a mountain bike). Space for big tires lets you tackle any route (unlike a road bike). And you can do that with one type of tire for everything or finetune your ride with multiple wheelsets or tires.

The U.P. fits mountain bike and gravel tires up to 2.1” (54mm) in 650b. It also fits 700c gravel, cross and road tires from 28-40mm wide (exact tire sizes depend on manufacturing tolerances and rim width, so always check and make sure you have 6mm clearance between tire and frame).

More importantly, and more difficult to achieve, the U.P. handles well in all these configurations, as customers, media and award judges confirm time and again. So whether you ride it with road or mountain bike tires, on pavement or off-road, you always have nimble, responsive and confidence-inspiring handling.
