I ride a Cotic X with a build somewhere between the Croix and its big brother, the Equilibrium disc (105 except for Tiagra shifters and 11-32 cassette, XT hubs, GP 4 Season tyres, EA50 finishing kit, BB5s).
Although it’s clearly a different bike from the Croix, the concept and my style of use are the same.
It’s one bike for everything. I do most of my miles on it: commuting, shopping, kids on the back, occasional longer road rides. Brilliant. 🙂
