From the minds behind BMC and Cervelo

Andy and Gerard created Open in search of a more pure mission: Design bikes they want to ride, build them with high quality materials in small batches, and sell them to other people looking for a great bike, great rides, and great service.

“What is truly amazing is the attention Open paid to making it work exceptionally well in every configuration. The U.P. doesn’t just accept different [wheel/tire] standards - each feels native.

Peloton Magazine

“The Open U.P. will change where you ride. A long-term review of this gravel/’cross/road bike proves that it really is as versatile as it promises. It feels natural on pavement and somehow still takes to the dirt like it was designed for it—a blend I’ve yet to experience with other bikes.”

Bicycling Magazine

“I really shouldn’t start my review with this, but I’m going to. The Open UPPER has become my all-time favorite bike. Period. End of story. If you buy one, you’ll love it.”
