Cervelo Caledonia 105 Disc Road Bike 2023
Fast, comfortable and dependable, Cervelo’s Caledonia 105 Disc Road Bike is a highly versatile option. Its fast enough for the club chaingang, has mudguard mounts for year-round use and is comfortable enough for double century rides. It also has clearance for 34mm tyres and an integrated bento box mount for extra storage on epic outings.
The carbon frame has a stiff bottom bracket area for efficiency combined with sufficient compliance elsewhere to absorb any vibrations from poor tarmac, and the slightly relaxed geometry helps the bike remain stable and easy to ride even at the end of a long shift in the saddle. Shimano 105 hydraulic disc brakes add confidence and control on fast descents or tricky corners in all weathers whilst the 11-34t cassette has sufficient ratios for any climb.
30mm Vittoria Zaffiro Pro V tyres further increase comfort and grip, with the 21mm internal width of the AlexRims Boondocks-5D wheels lending good support to the sidewalls. The rims are tubeless-ready too, making conversion simpler.
