For Your Big, Stupid Rides
On the fringes of cycling and triathlon, already endurance-oriented sports, there are athletes pushing their bodies and equipment to the limit. Ultra-distance, but ultra-fast. We call these Big, Stupid Rides, and since the introduction of the Caledonia in 2020, athletes around the world have been exploring just how big and just how stupid those rides can be. These athletes reach for the Caledonia-5. It’s built to handle long-distance, high-speed racing—with fit and handling geared toward comfort, but without sacrificing the Cervelo race bike feeling.
For the new Caledonia-5, we focused on improvements that would be meaningful for the people pushing it to its limits. The biggest thing you’ll notice is the addition of the in-frame storage first seen on P-Series. This isn’t designed to fit a burrito—there’s only room for a small multi-tool, tube, and a CO2 canister. Then we looked to comfort: The seat stays are dropped, similar to Aspero, which makes that rear triangle more acute, and more vertically flexible. At the same time, there’s a bit more downtube stiffness to maintain that pro-level responsiveness Caledonia is known for. You can still stuff some big tires (36mm) in there, and every bike comes with fender mounts.
In-Frame Storage
New this year on the Caledonia-5, the in-frame storage is designed for a tube, small multi-tool, and a CO2 canister. Out of sight, out of mind, until your tire makes the bad noise.The hatch is easily removable even with gloves on—just flip the lock and pull.
Aerodynamics
All Cervélo bikes are aero bikes. And when you’re on three days of panini and candy, running on fumes into Checkpoint One, you’ll appreciate the free speed. The completely internal housing and aero tube shapes team up to help you do battle against the wind.
Refine and Enhance
Caledonia-5 is meant for all-day riding, high-pace group rides, and routes featuring less-than-ideal tarmac.We kept all the good stuff, but made some key improvements. The bearing caps are now split so you can swap between the high and low bearing cap without bleeding the brakes if you need to make a fit change.
Hammerhead-Equipped
The Red AXS build comes with the all-new Hammerhead Karoo. The Karoo is the perfect companion for big stupid rides, and allows you to pick your preferred route surface (road, gravel) as you explore the limits of a “good idea.”
Reserve 42|49
Developed and tested using Turbulent Aero technology, the 42|49 is designed for everything you do, providing all-day capability with aerodynamic sensibilities. Raced at events as varied as the Paris-Roubaix and the Giro D’Italia, the 42|49 wheels have a lifetime warranty supported by a no-fault crash replacement.
Make Friends with the Wind
You can, in fact, reinvent the wheel. Meet Turbulent Aero, a unique R&D program that leverages real world wind data to create the most rapid, stable, and best handling wheels in real world riding conditions.
