OPEN U.P. Gravel Bikes For Sale - New & Used

Bikes are meant
to be used.

When Open Cycle’s U.P., Unbeaten Path, arrived at Sea Otter in 2015, it was teasing out what gravel riding should be. The U.P. looked like a dedicated road bike that could go off-road and fit 650b/27.5” wheels. The bike had the hallmarks of Gerard Vroomen’s design philosophy; simple, light, straightforward, and efficient.

The Open U.P. is one bike for all terrain. Neither a ‘cross racer nor a gravel racer, though it can do both. Not a bike packer. Just a bike you’ll want to ride all the time. It has room for 40mm wide 700c tires and 2.1” 650b/27.5”. The original bottom bracket was BB92, updated to BB386EVO. The original fork had post mounts; the update has flat mounts and doesn’t need an adapter. The shifting can be 1x, 2x, mechanical or electronic.
