Are you looking for a higher-end gravel frame, with a well-thought-out design and endless mounting possibilities? The OPEN U.P.P.E.R. Black Gravel Frameset is the top of the range model from the innovative company OPEN; their family of U.P. (Unbeaten Path) have appeared in countless magazines and won awards such as the Eurobike Gold Award. It includes the best of two worlds (road and MTB): the sporty position of the road bikes to go fast and the compatibility with 650b mountain tyres of up to 54mm.For the U.P.P.E.R., the designers of OPEN did not limit themselves to adapting a bit the successful U.P. model, but they redesigned the frame and its carbon layers entirely to be able to improve its lightness and rigidity even more. They managed to save 160g on the frame and 20g on the fork. Therefore, the frame only weighs 880g and the fork 370g.Other examples of the benefits offered are the internal wiring, the possibility of mounting disc brakes and to attach bottles or luggage in the upper tube and the indication of minimum insertion in the seat tube (not only in the seatpost). It perfectly combines functionality and aesthetics in the design, to which is added the elegant black of the U.P.P.E.R. Do you want to miss one of the most versatile and highest quality gravel bicycle frames on the market?
