With OPEN framesets, we give you the opportunity to get the one custom bike you've always dreamed of. Whether gravel or road bike, both are possible, and at a level that is hard to beat in terms of technical sophistication. That’s not all, however: simply contact our service department and together we will take care of your set-up. To help get you started, we present the 4 framesets with the all-rounders NEW U.P. and U.P.P.E.R. as well as the extremes WI.DE. and MIN.D. in more detail.

What is it about the last WI.DE. build that fascinates me? It’s clearly the juxtaposition of a modern frame philosophy with the vintage looks of the add-on parts. Get an idea of possible WI.DE. builds and click through the photos.


What could be better than a bike that’s assembled according to your own personal preferences? One that also gets a custom paint job! OPEN offers the possibility to order all frames in a "Ready-to-Paint" version. I opted for a muted, dark green that harmonises very well with the brown sidewalls on the tyres. Now I can say the bike is mine in every way.

The set-up of the OPEN U.P.P.E.R. was a highlight for me. The bike weighed in at just under 6.3 kg: an absolute lightweight.
Manuel, Workshop


All OPEN frames can be configured to cut a fine figure on the road. If you're looking for a pure road bike setup, the purist MIN.D. is the right choice. Lightweight construction fans and friends of classic bicycle aesthetics alike will get their money's worth here.

More about OPEN

OPEN Cycle is the high-end brand founded in 2012 by two industry experts, Andy Kessler and Gerard Vroomen. Known for developing innovative frame designs, they have provided the template for a modern gravel bike with the Model U.P. For all gravel riders who prefer wider tyres, OPEN offers the WI.DE. frameset. However, the bicycle maker not only brings you sophisticated gravel and road bike frames, but also sets standards in terms of design. This resulted in collaborations with bike-components and Continental, who together created a Limited Anniversary Edition bike to commemorate the 150th anniversary of the tyre manufacturer. Different frames offer you numerous possibilities to build your custom dream bike.
