The New U.P. with OPEN U-Turn fork and flat-mount disc brakes

Maximum versatility in a gravel/adventure frame.

Gravel/adventure bikes are really hitting their stride at the moment - read more about it on our blog - and a certain Mr Gerard Vroomen (of Cervélo fame) is at the forefront of this new movement.

Building the kind of bikes he wants to ride himself, he's hit on some ingenious solutions which make OPEN bikes uniquely versatile.

One of our Bespoke builds:

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.

"What is truly amazing is the attention Open paid to making it work exceptionally well is making [the U.P.] work exceptionally well in every one of these configurations. The U.P. doesn't just accept these different [wheel/tyre] standards - each feel native. - Peloton Magazine
