Product Description

As one of the premier gravel bikes available on the market, the U.P. easily swallows a 700 x 40c tire, or a 27.5 x 2.1" mountain bike tire. The U.P. can be used with more conventional 28mm road tires or cyclocross rubber up to 40mm wide - never before has a bike had this ability. The U.P. doesn't stop there; designed originally as a fat tire road bike, the U.P. features geometry that is uncompromised from its road bike roots, with smooth handling, peppy acceleration, and typical road bike fit. All you have to do is decide where you will ride it next, install the appropriate wheels and tires, then let the OPEN Cycles U.P. take you there.

This one-off build features a GRX 1x drivetrain and mechanical brakeset. Like what you see but want to take things in a different direction? Check out our OPEN UP Bike Builder page!
