The OPEN U.P. Unbeaten Path Force 1 Bike build is the dream gravel bike build is the final word for anyone looking for a 1x drivetrain. Paired to the veritable OPEN U.P frameset, we are proud to offer the U.P. as one of our go-to choices in the gravel bike world.

The OPEN U.P. Unbeaten Path Force 1 Bike uses the New U.P. or Classic U.P. Framesets as a starting point, with the option to build it in whatever way necessary. The Classic U.P. Frameset uses a 15mm thru axle and post mount disc brakes, while the New U.P. Frameset saves 60g at the frame thanks to flat mount disc brake mounts, and another 70g from the OPEN U-Turn carbon fork, shared with the luxe U.P.P.E.R. frameset. Both U.P. framesets fits up to 27.5 x 2.1” mountain bike tires, 700 x 40c gravel tires, or anything in between. The U.P does this while also allowing for short 420mm chainstays (shortest in class) and stack and reach geometry numbers that are closer to an endurance road bike than a honkin’ gravel or touring bike. Few bikes achieve true jack of all trades status, but the OPEN U.P. comes delightfully close.
