OPEN U.P.PER. 2.0 Frameset The OPEN U.P.PER. 2.0 is an ultra-light carbon gravel frameset built for riders who want race-bike speed without giving up the freedom to explore beyond the tarmac. The latest generation of OPEN’s iconic gravel platform combines low weight, aerodynamic refinement and the responsive handling that made the original U.P. a benchmark for fast gravel riding. At approximately 845 g for a size M frame, the U.P.PER. 2.0 creates an exceptionally light foundation for a high-performance gravel or all-road build. OPEN has added aerodynamic improvements where they matter most while retaining the frame compliance required for comfort and control on rough surfaces. The result is a bike designed to feel fast on gravel, efficient on the road and composed when rides become long, technical or unpredictable. A T47 threaded bottom bracket provides a practical and reliable foundation for your build, while compatibility with Shimano GRX Di2 and SRAM AXS electronic gravel groupsets gives you plenty of options for creating your ideal race or adventure setup.
