The Cervelo Men's Caledonia 105 Road Bike was conceived on routes that often play fast and loose with 'road ride.' The Caledonia was designed for durability, light weight, and aerodynamics to be in balance. Caledonia uses a standard round bar, stem and seat post, giving riders the option to build their ultimate ride without compromise. Integrated accessory mounts and hidden fender mounts keep the bike's refined lines so you can ride with lights and computers in a downpour and still look fast. Modern road riders are looking for bikes to handle long distance, high pace, no limits and offer maximum fun. By placing lower modulus carbon in key areas to mitigate the brittleness of hi-modfiber-the bike isn't delicate. It is made for the way we ride and accommodates 34mm tires or 31mm with fenders.
