Have you been looking for a higher-end gravel frame, with a carefully considered design and countless mounting possibilities? The OPEN U.P.P.E.R. Black Gravel Frameset is the top of the line model from the innovative company OPEN; their family of U.P. (Unbeaten Path) have been featured in countless magazines and won multiple awards like the Eurobike Gold Award. It comes with the best of two worlds (road and MTB): the sporty position of the road bikes for going fast and the compatibility with 650b mountain tires of up to 54mm.

For the U.P.P.E.R., the OPEN designers did not start by changing the successful U.P. Model slightly, but they redesigned the whole frame and its carbon layers completely to be able to improve its lightness and rigidity even more. These changes allowed them to save 160g on the frame and 20g on the fork. As such, the whole frame only weighs 880g and the fork 370g.

Some of the features include the internal wiring, placing bottles or bags on the upper tube, the possibility of mounting disc brakes, and the indication of minimum insertion in the seat tube (not only in the seatpost). The design combines perfectly aesthetics with funcitonality, to which is added the elegant black color of the U.P.P.E.R. You do not want to miss one of the most versatile and highest quality gravel bike frames on the market.

About OPEN

'Working hard to stay small', that is the motto of OPEN. Does it sound contradictory? Well, that's what the two founders of the Swiss company pursue. They are two faces known in the world of cycling: Gerard Vroomen and Andy Kessler. Vroomen has worked for Cannondale, Scott, BMC (he was CEO for 7 years) and Cerveló; here he met Kessler, who had been one of the co-founders.

With their extensive experience in the two largest sectors of cycling, road and mountain bikes, they founded OPEN to design and build a bike that they would like to use. They wanted to focus on the design of the bikes and deal with customers and forget the concerns of large companies: sponsorships, marketing, complete bicycles, flashy offices, etc.

Even so, without any marketing, the frames have won awards such as the Eurobike Award and have been praised by numerous cycling magazines that have highlighted their ingenious and light design, their compatibility with numerous components and above all, its versatility.
