Clearance for cross, road and mountain bike tires, a cross/road position and compatibility with cross/road & mountain bike drivetrains make the U.P. geometry the most complicated we’ve ever worked on. But we’re ecstatic about the result.
Keep in mind that the seattube is designed to be offset, so that your seatpost doesn't have to be. This saves a bit of weight. It also means that the toptube length appears a bit longer than the frame really is, yet another reason why toptube length is a bad measurement to rely on. Best to use stack and reach.

|¹||These suggested rider heights are approximations, there is no substitute for a complete fit analysis including several body dimensions or the measurements of the current set-up of your gravel/cross/road bike.|
|²||Standover height is measured to the top of the toptube directly above the bottom bracket and depends slightly on the exact tire size used.|
As you can see, the chainstays are quite short for a cross/gravel bike, despite the ability to fit the massive 54mm tires in. That's one of the benefits of the dropped drive-side chainstay.
