Cervelo Caledonia-5 Ultegra Di2 Disc Road Bike 2021
Perhaps the perfect combination of comfort and performance, the Caledonia-5 Ultegra Di2 Disc Road Bike from Cervélo offers accessible, real-world speed on all kinds of roads. Borrowing heavily from the racy R5 and tough Aspero, the Caledonia uses a carbon frame which has been tuned to offer plenty of compliance without sacrificing the power transfer and aerodynamics necessary for effortless riding. A more stable geometry helps on endurance rides but doesn't inhibit the bike's pace at all. Clearance for 34mm tyres and hidden mudguard mounts underline the bike’s practical credentials, and yet the frame still weighs less than 1,000 grams so hills and mountains can be dispatched with impunity.
Equally performance-oriented is Shimano’s electronic Ultegra Di2 groupset, with ratio selection actuated by just a light press of the lever. When it comes to speed control or stopping, the hydraulic disc brakes are just as impressive, providing tireless power in all weathers. The tubeless-ready Reserve 35mm DT370 carbon wheels are both light and strong, making them an ideal pairing for this versatile bike. 30mm Vittoria Rubino Pro TLR G tyres are also fast and comfortable, with their extra volume offering tangible performance benefits on long rides with varied surfaces.
