Full carbon gravel bike, Billfish brand (same manufacturer as the French brand S1néo), Freedom 1 model, size 57. It was used for 1 year as a cyclocross bike by my son (U17 category), then I used it for a few rides over 2 years for gravel (my son is 1.85m and I am 1.79m). Very good efficiency, good stiffness, 2-3 small chips due to use. It is currently fitted with an Ltwoo Di2 electronic groupset (carbon levers and derailleur), a very reliable Chinese groupset with the possibility, via the app, to choose whether to ride in 10, 11, or 12 speeds (upgradable). I am reinstalling the original groups...
