OPEN U.P. 2.0 / U.P.PER. 2.0
2026 · 700c wheels · 5 sizes
Second generation of OPEN's performance gravel frame, built for fast riding on 35 to 46 mm tyres with a U-Turn Aero fork. The U.P. 2.0, the lighter-layup U.P.PER. 2.0 and the U.P. 2.0 Adventure (with the U-Turn Adventure cargo fork) share this frame and one geometry table. OPEN writes fork length and head tube as a sum, so axle-to-crown and head tube are listed separately here. OPEN does not publish fork offset or trail. OPEN does not publish fork offset or trail for this bike. The offset used here (50 to 63 mm) is worked out from OPEN's own stack, reach, head angle, bottom bracket drop, chainstay and wheelbase, which pins it to within a millimetre or two, but it is not a published figure.
