Caledonia 105 Di2

The Caledonia lineup spans four builds, ranging from entry-level mechanical shifting to premium wireless electronic groupsets. The frame and carbon fork remain identical across the board, featuring clearance for 34mm tires, or 31mm when utilizing the hidden fender mounts. All models also include a removable front derailleur mount for riders interested in a clean single-chainring setup.

The ladder begins with the mechanical Shimano 105 build, which keeps the entry price accessible but relies on a basic alloy seatpost and heavy Vision Team i23 aluminum wheels. Stepping up to the 105 Di2 or SRAM Rival AXS models introduces electronic shifting and upgrades the seatpost to Cervelo’s SP19 carbon model, which helps mitigate road vibration at the saddle. However, these mid-tier options still utilize the same entry-level Vision alloy wheelsets.

The flagship Force AXS build represents a significant jump in both price and performance. It is the only model in the standard Caledonia range to include carbon wheels, rolling on a Reserve 40/44 wheelset that materially reduces rotational weight and improves aerodynamic efficiency. Across all builds, the drivetrain gearing is tailored for endurance riding, pairing semi-compact cranksets with wide-range cassettes to handle steep, sustained climbs.

Reviewers consistently praise the Caledonia for its balanced ride quality, noting that it successfully merges aerodynamic efficiency with long-distance composure. On the road, the frame feels stiff and responsive under power, yet the overall handling leans toward predictability rather than nervous agility. Testing the bike on varied terrain, one reviewer noted it delivers a "smooth-gliding feel" (BikeRadar) that effectively mutes road buzz, largely thanks to the high-volume tires.

When pointed downhill or pushed on flat stretches, the bike maintains momentum easily. The geometry choices create a sense of "straight-line stability" (Velo), making it highly capable on fast descents. However, this longer wheelbase and relaxed front end mean it is not a pure criterium racer. In tight corners, the steering can feel slightly muted, with one tester observing "somewhat sluggish handling" (Velomotion) during highly technical maneuvers.

The primary critique across reviews centers on the stock touchpoints and rolling weight. While the carbon frame itself is highly regarded, the standard aluminum handlebars and heavy stock wheelsets on lower-tier builds are frequently cited as performance bottlenecks. Additionally, the standard round seatpost does not offer the same vibration damping as the proprietary carbon post found on the Caledonia-5. Despite these component compromises, the consensus frames the Caledonia as an exceptionally versatile platform, serving well as a "roadie’s exploration machine" (Velo) for riders who value durability and multi-surface capability over absolute low weight.
