Bikes
When gravity calls, you can either fight against it or commit to the ride. Don’t be afraid to take things too far, push harder, and dare where others hesitate. Relentless evolution is the only way forward, because the finish line is just the beginning of something greater.
Rallon is a new breed of gravity bike, forged through years of development in the lab and on the race track. Its low center of gravity delivers unmatched stability, precision, and control at race speed, while supple suspension maximizes traction and opens up new line choices. And because no two tracks—or riders—are the same, Rallon offers unparalleled adjustability, letting you fine-tune performance for every ride.
Focus on fast
Rallon begs for a challenge. With planted handling, unbeatable suspension performance, and a low center of gravity, it’s built to to take your riding to the next level.
Rallon brings together a stiff carbon frame, durable alloy linkage, and our GravityLink to form a structure made to handle the demands of modern Enduro—from rugged stages to full-throttle descents.
More adjustability than ever—on and off the trail. From geometry to ride feel, Rallon is built to let you dial in the perfect setup for every ride.
Built For Abuse
Rallon will get you all the way to the bottom with a quiet, reliably equipped frame and gravity standard components.

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.
Like all Cervélos, Caledonia-5 is UCI approved, and carries a lifetime warranty. We make race bikes, and we make them to last.
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.
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.
In 2019, Áspero took the gravel world by storm, heralding a "new era of speed in gravel." Fun, but flat out. The new Áspero remains true to its original brief, but with some improvements: a threaded BB shell, neater cable routing, and a UDH-compatible derailleur hanger for those who want to use SRAM's Transmission drivetrains. And it's more aero, of course. In the case of Áspero, aerodynamic performance is less about pure speed as a result of drag reduction, and more about conservation of energy. After a big day in a headwind, the three watts saved over the previous Aspero might add up to one less energy gel your stomach has to digest—WORTH IT.
In addition to the drag reduction, we also dropped the seat stays to give a bit more compliance out back, and reduced front-end stiffness slightly to make the last hours of a long race less painful. Between those dropped seat stays, we added in a bit more clearance for mud, too, taking what we learned from R5-CX (and the Unbound mudfest in 2023). It's a lot of seemingly small improvements, but they add up to a lot. The result is a bike that feels a lot like the original Áspero, but is faster, more comfortable, and more versatile.
THREADED BOTTOM BRACKET
Aspero uses the asymmetrical T47a threaded bottom bracket we pioneered on R5-CX. It's a simple, rider-serviceable interface that allows us to deliver the benefits of BBRight in a more user-friendly form.
UNIVERSAL DERAILLEUR HANGER
We used SRAM's Universal Derailleur Hanger (UDH) standard on the new Aspero. It's ideal if you want to live your best 'business in the front, party in the back' life with one of SRAM's Transmission drivetrains today, and ensures compatibility for future drivetrain developments.
INTERNAL CABLE ROUTING
Aspero shares the same bearing dimensions as R5, Soloist, R5-CX, and Caledonia, which means you can use any combination of bearing caps and stems. Want a super-racy, fully-internal look? Grab the ST31 and HB13 from R5.
