The OPEN U.P.P.E.R. Force 1 bike build is the dream build is the final word for anyone looking for a 1x drivetrain. Paired to the veritable OPEN U.P gravel bike frameset, we are proud to offer the OPEN U.P.P.E.R. Force 1 Bike as one of our go-to choices in the gravel bike world.
The OPEN U.P.P.E.R. Force 1 bike build starts life with the ultralight OPEN U.P.P.E.R. frameset, with the option to build it in whatever way necessary. Compared to the standard U.P. frameset, the U.P.P.E.R. lives up to it’s heightened name; it’s OPEN U-Turn fork is the lightest gravel bike fork in class (375g), while flat mount disc brake mounts combine with a higher modulus carbon fiber layup to save a substantial 310g compared to the Classic U.P. Like the original frameset, it shares the same geometry, and importantly tire clearance; it fits up to 27.5 x 2.1” mountain bike tires, 700 x 40c gravel tires, or anything in between. It achieves this while using stack and reach numbers that are closer to an endurance road bike than a plodding touring bike; a slacker than average headtube angle, stubby 420mm chainstays, and Flatout downtube mean the bike is a performer, both on and off pavement. Other features include three water bottle mounts, a top tube bento box mount, and pencil-thin seat stays for improved compliance over rough roads.
