The D-shaped steerer tube ties into Cervélo's broader cockpit ecosystem while maintaining compatibility with standard 1-1/8" stems, so dialing in fit doesn't require proprietary parts or waiting on brand-specific inventory. Two-piece semi-integrated bearing covers simplify headset adjustment—a small detail that shop mechanics and home wrenchers alike will appreciate during seasonal tune-ups. The T47 threaded bottom bracket shell combines generous bearing surface area with straightforward installation, eliminating the creaks and press-fit complications that plague many modern carbon frames. These details position the Caledonia as the most customizable platform in the lineup, engineered for riders who want performance without the maintenance compromises that often accompany it.

Shimano's 12-speed 105 R7100 groupset handles shifting duties through mechanical cables, offering the reliability and tactile feedback that many riders still prefer over electronic alternatives. Mechanical derailleurs mean no batteries to charge, no wireless pairing to troubleshoot, and service that any shop can handle without specialized diagnostic tools. The crankset pairs 52/36-tooth chainrings with an 11-34-tooth cassette, spanning gear ratios suitable for both flat group rides and sustained mountain grades where a bailout gear matters. Hydraulic disc brakes use Shimano's R7120 levers, providing consistent stopping power regardless of weather conditions—a meaningful advantage for the all-season riding the Caledonia invites.

Vision Team i23 alloy wheels roll on J-bend spokes and accept tubeless tires without modification. The 23mm internal width matches well with the included Vittoria Corsa N.EXT TLR tires in 700x32c, a size that balances rolling efficiency with compliance over imperfect surfaces. Thru-axle spacing follows the 12x100mm front and 12x142mm rear standard, ensuring compatibility with the majority of aftermarket wheelsets when the upgrade itch arrives. The rear hub uses a Shimano HG freehub body compatible with both 11 and 12-speed Shimano cassettes.

Cervélo's own components handle cockpit duties. The HB23 alloy handlebar pairs with the ST36 alloy stem, both designed to complement the Caledonia's external routing capability while maintaining a clean appearance. A 27.2mm alloy seatpost and Cervélo saddle complete the contact points—serviceable stock choices that invite upgrades as preferences develop. Shimano RT66 6-bolt rotors handle braking surfaces, and the frame includes integrated provisions for Cervélo's front computer/accessory mount alongside removable fender mounts for commute-ready versatility.

The all-carbon fork uses a tapered steerer with aerodynamic thru-axle integration that maintains the frame's clean visual language. FSA supplies the IS2 headset with 36/45-degree bearings top and bottom. Six sizes span the range from 48 through 61, each maintaining consistent handling characteristics through careful geometry adjustments at each size point.
