OPEN U.P.P.E.R. Frameset

The U.P.P.E.R. Frameset by OPEN - A versatile lightweight

The OPEN U.P.P.E.R. frameset is made of super-light carbon and impresses with versatility on gravel tracks or on the road. Compared to its relative, the U.P., it weighs about 180 g less, which contributes to further performance improvements. The geometry is based on endurance road bikes and features a longer reach and a pleasant degree of stiffness. This way, you can also manage long days in the saddle comfortably and efficiently. The lowered right chainstay opens up space to mount up to 2.1 inch wide tyres. But even with narrow road bike tyres, the U.P.P.E.R. is a good choice. You need a high-end bike for cyclocross races? There are no limits to your imagination with this high-performance frame and U-Turn fork combo. Thanks to internal cable routing, your shifting system remains protected from dirt and moisture.
