A full season on the Cervélo Caledonia with Shimano Ultegra Di2 12-speed. Stock wheels swapped on day one for Easton EA90 SL. Cassette changed from 11–34 to 11–30 for flat Minnesota riding. The bike that changed the shop’s opinion on endurance road bikes.
Frame
The Caledonia is Cervélo’s endurance road bike, but it doesn’t look like one. Higher stack, longer wheelbase, slightly slacker front end — but the silhouette still follows Cervélo’s aero-influenced design language. It looks fast. Tire clearance to 34mm, which is plenty for rough pavement or light hardpack. External cable routing, which is actually preferred here — easier to service the headset, keep everything quiet, and with Di2 there are only two brake housings anyway.
The bolt-on top tube bag mount is a nice touch — same as the gravel bikes. And the remote buttons on the Ultegra hoods for changing Garmin pages are legitimately useful.
Drivetrain
Ultegra Di2 12-speed. Stock 11–34 cassette was swapped to 11–30 for local flat riding — better gear spacing for the terrain. The older Stages left-side power meter (11-speed) has a Q-factor mismatch, but a pedal washer shim fixes it close enough that you never feel it. The D1 Ultegra hoods with the small toed-in adjustment feel excellent. Strongly prefer Shimano on the road over SRAM AXS for pure road riding.
Fit
Stock handlebars swapped for the Cervélo carbon flared road bar — same bar used on the Áspero-5. After spending time on gravel bikes, a slight flare feels natural without looking like a gravel cockpit. Zero-offset seatpost replaced the heavily offset stock post to get the position right.
How It Changed Things
This bike completely changed the shop’s opinion about endurance road bikes. Coming from years as a Trek Domane dealer, endurance geometry meant nice-riding but uninspiring. The Caledonia is the opposite — comfortable, handles great, and genuinely fast. It’s a bike you want to put long miles on, and also a bike you can go chase segments with. Since getting on it, pavement riding went up significantly relative to gravel. That doesn’t happen with a bike you don’t enjoy.
If you’ve dismissed endurance bikes because you thought they were boring or slow, the Caledonia is worth a serious look. It changed the shop’s mind on the category.
