The Open U.P.PER is designed to use road, road plus, and even mountain wheels with uniform handling. The Open U.P.PER can be configured in a variety of ways for confident, fast, rides on all surfaces. From the creators of BMC and Cervelo - Open utilizes many innovations widely copied today such as the dropped chainstay and double-dropped chainstay as seen on the Open WI.DE. This creates enough room for high volume tires without increasing the Q-Factor or sacrificing pedaling efficiency. Like most things, carbon layup is not as simple as black or white and Open has developed a lightweight yet durable blend. The Open U.P.PER frameset weighs 880g. Don't sacrifice beauty for technology with Open's elegant cable routing options, if you don't want to run wireless. Still not convinced?
