OPENCycle OPEN U.P. GravelPlus Disc Flat Mount Frameset green

FAST, FUN, FREEDOM
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.

The third generation U.P. & U.P.P.E.R. frames are lighter, nimbler and more fun than ever. They also still pass our ultimate test: We only offer frames we want to ride ourselves.

And because we’re “working hard to stay small”, you always speak directly with the people who developed the bikes.

WHAT IS THE
U.P.(P.E.R.)?
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.

TWO VERSIONS
The differences between the U.P. and U.P.P.E.R. are weight and color:

U.P.P.E.R. frameset saves approx. 180g over the U.P.
U.P.P.E.R. is available in matte black, the U.P. in green and blue. Both are available in RTP (Ready-To-Paint) so you can have it custom-painted.

There is no difference between the U.P. and U.P.P.E.R. in geometry, durability, stiffness, tire clearance or capability.
