U.P.PER. CONCE.PT CHASSIS

The first of a new wave of OPEN frames, the Open Upper Concept shows our new direction. The focus remains on comfort, with aerodynamic features where they matter and do not interfere with that comfort.

The U.P.PER. CONCE.PT. is paired down to the essence for the purest riding experience. It's only available in sizes M & L. After that, the regular U.P. and U.P.PER. will be available in five sizes.

Finish options are carbon black with a protective clearcoat and OPEN logos or Raw Ready-to-paint for those wishing a custom paint project.

The CHASSIS includes frame, fork, seatpost and integrated one-piece bar/stem.

The U.P.PER. CONCE.PT. ships from April 2025 depending on your order date and size. We can confirm this to you once we have fixed your bar/stem and frame size.
