A BIKE FOR THE WAY RIDERS RIDE Caledonia doesn&&';;t fit in a box nicely, and we like it that way. It was conceived on Cervelo&';s Thursday night rides-routes that often play fast and loose with 'road ride.&&';; Modern road riders are looking for bikes to handle long-distance, high pace, no limits, and offer maximum fun-the Caledonia delivers performance, comfort, and speed. Oh, and you can fit a 34mm tire in there. Or 31mm with fenders. REMOVABLE FDM Our bolt-on front derailleur mount is made from high-strength aluminum alloy and attaches to the frame with two countersunk screws. This allows for easy replacement in the event of damage but also enables you to adapt to new standards as they become available or remove the front derailleur mount completely if you choose a 1x system. INTEGRATED ACCESSORY MOUNTS Integrated mounts enable the use of fenders, lights, and computers without compromising the aerodynamics or structure of your bike. The built-in mount systems provide a simple and clean-looking solution.
