A versatile weapon capable of tackling nearly any terrain, the U.P.P.E.R is arguably the premier bike for racing - and winning - gravel and mixed-terrain events. It uses the same dropped-chainstay design to clear huge (42mm x 700 or 2.1" x 27.5") tires without making the back end of the bike longer than a stretch limo. It still offers as much freedom as we want to chow down on, but with complete bike weights testing the UCI-mandated 6.8kg/15lb weight limit.

Available in any color you like, as long as it's black. Of course, it can be custom painted to meet your wildest dreams. Frameset includes fork, headset, seat collar clamp, thru-axles, a replacement derailleur hanger, and fittings for all popular cable routing options.

Need help building one into your all-terrain dream bike? Give us a call and we'll square you away!
