Cervelo Caledonia-5 Disc Ultegra Di2 11 Speed with Zipp 303S Bike Accessories_Stem it forces the air moleculesA NEW BIKE FOR CLASSIC RIDES The Caledonia is the bike we keep reaching for when we know the odometers going well past the triple digit mark. Long rides invariably have some smooth tarmac, some junk pavement over backroads, a cutty singletrack connector, and maybe even your own local Strade Bianche sector. So we built a bike that could take on all of them, do it well, and fit fenders in case the ominous clouds turn into a downpour 130km into your day.
