Open Cycle U.P.
What Is the Open Cycle U.P.? The U.P. (Ultimate Performance) is the bike that started the dual-wheel-size gravel trend — designed by Gerard Vroomen (co-founder of Cervelo) to accept either 700c road wheels with 40mm tyres or 650b mountain bike wheels with 2.1 tyres on the same frame. Every major gravel brand has since copied this concept; Open did it first and still does it best. Key Features Full carbon frame — manufactured at the Cervelo production facility Accepts 700c with up to 40mm tyres OR 650b with up to 2.1 tyres Road-fast or trail-capable: one frame, two complete identities Race geometry with enough stability for technical off-road riding Internal cable routing, Di2 and eTap AXS compatible Swiss engineering — designed and developed in Switzerland Who Is the Open U.P.
