Bergamont Grandurance 8 (2021) size 55 - GRX 1x11
This Bergamont Grandurance 8 (model 2021) from Gravel has an AL-6061 ultra lite aluminum frame and carbon fork. It is set up with an effective Shimano GRX single-crown 11-speed mixed groupset, RX600 series for the shifters and RX800 series for the crankset and rear derailleur. It is equipped with hydraulic brakes. The front sprocket is 40 teeth, while the rear cassette, after an upgrade made in June 2024 along with a new chain mounts a Shimano XT 10-51 sprocket set, which allows for more versatility than the factory configuration, especially when climbing. The wheels are Syncros signature aluminum, as are the handlebars and seatpost. The wheels are tubeless and are equipped with Vittoria's internal salcicciotto for added safety in case of a puncture. The stated weight is 9.8 kg while the geometries are typical of modern gravel bikes with an open headtube (71°) and a fairly straight seatpost angle (frame length of 425 mm and BB drop of 70 mm; in size 55 cm, the head angle is 71.5° and the seat angle 73.5°, stack and reach 581 mm and 383 mm respectively). The head tube has been replaced with one from Specialized 100mm. The bike is distinguished by the low rear chainstay and differentiated tube sections that give it aerodynamics, as well as the internal cable routing inside the frame that gives it a clean look. The frame and fork were immediately covered with a clear protective plastic film to protect them from scratches. Aside from normal wear and some imperfections the frame and fork are intact. The bike has never been dropped.
