The U.P. fits mountain bike tyres up to 2.1" wide. But you can also fit a 40mm cross tyre, or a 28mm road tyre, or anything else in-between (exact sizes depend on manufacturing tolerances and rim width, so this is a guideline - we will advise on specifics as part of the build!).
Build it however you want, swap wheels at will. The U.P. will take you where you want to go.
At Bespoke we're all about achieving the perfect fit. Not sure what size you need? Book a bike fit with us first.
We can supply the frameset "as is", for you to build to your own requirements. But most of our customers opt to have us build the bike of their dreams. We have access to the full range of componentry from all the world's leading brands. Check out our Build Gallery for examples of previous Bespoke builds.
