Variety is the spice of life, and this extends to bicycles. Now more than ever consumers refuse to put up with the staid and lackluster, and aim for capability. The capability to ride both on and off road with startling efficiency, stiffness and reliability with as little weight as possible, and geometry that works well both in a road group ride and a solo lunch dirt ride. Few bikes successfully do all of these things. The OPEN U.P.P.E.R. Ultegra Di2 bike might be the best gravel bike yet to do all of these things
The OPEN U.P.P.E.R. Ultegra Di2 bike 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.
The U.P.P.E.R. is all about versatility, so we’ve hand selected parts that offer awesome performance on road, cross, gravel, bike packing, or anything that may lie ahead. A Shimano Ultegra Di2 drivetrain is exceptionally smooth, reliable, offers wide gear range options. We use an Easton alloy cockpit and seatpost as a starting point, with a Fabric Scoop saddle alongside. Stan’s No Tubes is synonymous with light weight tubeless wheel and tire setups, and our two preferred wheelsets, the Stan’s Grail S1 wheelset for 700c or the Stan’s Arch S1 wheelset for 27.5”, provide an excellent combination of reliability, stiffness, and low weight. 700c wheels save weight and roll better on smoother surfaces, while the 27.5” mountain bike wheelset offer additional durability for rougher trails, and their extra width gives knobbies better bite and a plusher ride.
Whether you’re heading to Salt Lake City, or prefer we ship your OPEN U.P.P.E.R. Ultegra Di2 bike to you, we’ll do a full, professional bike build, dialing in shifting and braking, truing wheels, etc. If you’re unsure about sizing, give us a call or email us at firstname.lastname@example.org to talk through geometry and fit. And although this is a “stock bike,” we are more than happy to discuss options of this build.
