The OPEN UPPER 2.0 Frameset is a fast, light, and agile gravel bike designed for riders who want speed without sacrificing comfort. Whether you’re racing gravel, tackling fast tarmac rides, or packing for an overnighter, the U.P.P.E.R. delivers efficient performance across mixed terrain. Its frame blends aerodynamic shaping at the front with proven compliance in the rear, making it easier to hold your position over long distances while still cutting through the wind. Made entirely in Portugal, this frame reflects OPENs commitment to sustainability and precision quality.

Designed to fit tires between 35mm and 46mm, the UPPER provides sharp, responsive handling without giving up comfort. The carbon frame uses ultra-thin seatstays to soak up bumps, while straight chainstays maximize power transfer. The deep headtube, internal routing, and aero-specific handlebars all contribute to its low-drag profile, while features like a T47 threaded bottom bracket and UDH derailleur compatibility make it easy to maintain and upgrade. This is a bike thats built to go fastbut also built to last.
