OPEN UPPER Frameset

Building upon its OPEN U.P. bike, Open Cycle has kept the same geometry and tire clearance of the U.P., but differed its carbon layup, fork, disc brake mounts, and thru-axles to create the all new OPEN U.P.P.E.R. Frameset. With its lighter weight, enhanced stiffness, and increased simplicity, the OPEN U.P.P.E.R. Frameset looks and rides like a road bike, but can also conquer the roughest dirt trails and gravel roads. Just like the U.P., the U.P.P.E.R. bike fits up to 2.1" wide mountain bike tires, but also a 40mm wide cross tire or a 28mm road tire. All tire sizes are accommodated without affecting the handling or geometry of the bike. Thus essentially like a three-in-one bike, you can take the U.P.P.E.R. on virtually any terrain just by switching to the appropriate tires. To help accommodate bigger tires and narrower Q-factor cross/road cranks and chainrings, the U.P.P.E.R., like the U.P., uses a dropped right chainstay to create a wider area. A dropped chainstay also increases stiffn
