When Open bikes arrived on the scene, heralded by their superlight hardtail, the ONE, in 2012, the bike world (mostly) yawned. Then, when the U.P all-road bike arrived in 2015, a shift happened. The upstart brand, brainchild of two industry veterans, helped completely change the way the industry thought about road bikes, with wide tires, disc brakes, and thru-axles suddenly becoming normal.
The Open U.P is still one of the most versatile gravel, adventure, or even road platforms available today, capable of tackling an extreme swath of terrain and events, and its ultralight Open Upper sibling ups the ante in the performance arena.
Born in Switzerland, Open bikes are the result of a collaboration between former BMC general manager Andy Kessler and Cervélo co-founder Gerard Vroomen. Born out of a desire to simplify, Open's disruptive designs continue to shift perceptions on what bikes are capable of and where they can take the rider, with the award-winning UP setting the bar to which all other "mixed-surface" bikes are measured.
