The Caledonia-5 is built for what the brand calls Big, Stupid Rides — ultra-distance, ultra-fast events that push riders to rethink what road bikes are capable of. It's not a marketing tagline, it's a design brief. The riders reaching for this bike aren't stopping at a century. They're chasing randonneuring records, racing multi-day ultra events, and stringing long days together in search of something a pure race bike can't give them: the ability to go very fast for a very long time without the bike making the day harder than it needs to be.\u003c\/p\u003e\n\u003cp\u003eThe \u003cstrong\u003eCervelo Caledonia-5 Red AXS Bike\u003c\/strong\u003e is the top build of that platform: SRAM Red AXS 12-speed wireless electronic shifting, and Reserve 42\/49 carbon wheels on DT Swiss 240 hubs included in the spec.

Cervélo dropped the seat stays — borrowing the approach from the Aspero gravel platform — making the rear triangle more acute and more vertically flexible. That compliance registers on rough surfaces and broken road where a pure race bike starts to tax your body before the distance does. At the same time, Cervélo stiffened the downtube to preserve race-level responsiveness in the power transfer. The result is a bike that holds the Cervélo race feel while absorbing the kind of sustained punishment that endurance riding produces. In-frame storage, lifted from the P-Series TT platform, fits a tube, small multi-tool, and a CO2 canister behind a glove-friendly hatch. Fender mounts come standard, and tire clearance runs to 36mm. Fully internal cable routing and aero-optimized tube shapes keep the Caledonia-5 honest on the aerodynamics front, because free speed compounds over long distances.\u003c\/p\u003e\n\u003ch3\u003eDesign Benefits\u003c\/h3\u003e\n\u003col class=\"design_benefits\"\u003e\n\u003cli\u003e\n\u003cstrong\u003eDropped seat stays — compliance where it counts.\u003c\/strong\u003e Borrowed from the Aspero gravel platform, the lowered stay junction makes the rear triangle more acute and more vertically flexible.

Introduced in 2020, the Caledonia platform was designed specifically for athletes who want long-distance, high-speed capability with fit and handling calibrated for comfort over hours, without giving up the race bike feel Cervelo builds every frame around.

The all-carbon fork is built to the same standard. Two notable frame details separate the Caledonia-5 from its predecessors: in-frame storage and split bearing caps. The in-frame storage hatch in the downtube holds a tube, a small multi-tool, and a CO2 canister. It opens with gloves on — flip the lock, pull the hatch — and disappears completely otherwise. The split bearing caps allow stack height adjustments for fit changes without bleeding the brakes.

The crankset includes an integrated power meter — included in the build at this price, not a retrofit. Force AXS delivers the same precision shifting as RED AXS in real-world use, with marginally more weight.

The asymmetric depth is intentional: the shallower front handles crosswind stability at speed, the deeper rear captures aerodynamic advantage in the more stable rear position. Reserve developed these wheels using Cervelo's Turbulent Aero program, which models wheel performance using real-world wind data across the full range of yaw angles riders actually encounter — not idealized tunnel conditions. These wheels have been raced at Paris-Roubaix and the Giro d'Italia, and they come with a lifetime warranty backed by no-fault crash replacement.

Since the original Caledonia arrived in 2020, the platform has found a devoted following among riders who want the precision and responsiveness of a Cervelo race bike with the comfort and range to go longer than common sense would suggest. The Caledonia-5 refines that formula with targeted structural updates, practical storage solutions, and a build spec that's genuinely ready to race the day it arrives.\u003c\/p\u003e\n\u003cp\u003eTwo key structural changes define the Caledonia-5 relative to its predecessor. First, the seat stays are dropped — the same approach Cervelo used on the Aspero gravel bike — which makes the rear triangle more vertically flexible and absorbs road chatter over long days in the saddle. Second, the downtube has been stiffened to preserve the crisp, pro-level responsiveness the Caledonia platform is known for under hard efforts. The result is a frame that gives where it should and doesn't where it shouldn't: compliant at the contact points, firm through the drivetrain. Aero tube shaping and fully internal cable routing reduce drag across the entire front end, while fender mounts come standard — an honest acknowledgment that riders who cover serious distance will eventually find themselves in the rain. New to the Caledonia-5 is a practical in-frame storage compartment: sized for a tube, multi-tool, and CO2, accessible through a glove-friendly flip-lock hatch tucked cleanly into the downtube.\u003c\/p\u003e\n\u003cp\u003eThe Ultegra Di2 build is anchored by Shimano's 12-speed electronic groupset in full R8100\/R8150\/R8170 spec — derailleurs, levers, and calipers are all current-generation Ultegra Di2. The crankset is a Shimano Ultegra R8100 fitted with a 4iiii Precision Pro GEN3+ Dual Sided power meter, measuring both legs independently for a complete power picture on every ride. A 52\/36 chainring with an 11-34 Ultegra cassette covers the full range of terrain the Caledonia is designed for. Rolling stock is Reserve 42|49TA carbon wheels on DT Swiss 350 hubs — an asymmetric setup where the 42mm front rim optimizes handling and crosswind stability while the 49mm rear adds aerodynamic efficiency where wind matters most. Vittoria Corsa N.EXT TLR tires in 700x32 provide a premium tubeless-ready racing surface, and a pair of Arundel Mandible carbon bottle cages arrive already mounted. Max tire clearance is 36mm for riders who want more volume on rougher roads.\u003c\/p\u003e\n\u003ch3\u003eDesign Benefits\u003c\/h3\u003e\n\u003col class=\"design_benefits\"\u003e\n\u003cli\u003e\n\u003cstrong\u003eDropped seat stays for vertical compliance.\u003c\/strong\u003e Cervelo borrowed the seat stay configuration from the Aspero gravel bike, making the rear triangle more acute and vertically flexible.

The dual-sided power meter, asymmetric wheelset, and in-frame storage are substantive details that reflect careful decisions about what long-distance riders actually need. For those chasing big days with race-level performance, the Caledonia-5 delivers Cervelo's race bike character in a format built to last all day.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"Cervelo","offers":[{"title":"Five Black \/ 48cm","offer_id":44804863623212,"sku":"0M0CFBUI1C48","price":8950.0,"currency_code":"USD","in_stock":true},{"title":"Five Black \/ 51cm","offer_id":44804863655980,"sku":"0M0CFBUI1C51","price":8950.0,"currency_code":"USD","in_stock":true},{"title":"Five Black \/ 54cm","offer_id":44804863688748,"sku":"0M0CFBUI1C54","price":8950.0,"currency_code":"USD","in_stock":true},{"title":"Five Black \/ 56cm","offer_id":44804863721516,"sku":"0M0CFBUI1C56","price":8950.0,"currency_code":"USD","in_stock":true},{"title":"Five Black \/ 58cm","offer_id":44804863754284,"sku":"0M0CFBUI1C58","price":8950.0,"currency_code":"USD","in_stock":true},{"title":"Five Black \/ 61cm","offer_id":44804863787052,"sku":"0M0CFBUI1C61","price":8950.0,"currency_code":"USD","in_stock":true},{"title":"Sandstone \/ 48cm","offer_id":44804863819820,"sku":"0M0CFBUI2C48","price":8950.0,"currency_code":"USD","in_stock":true},{"title":"Sandstone \/ 51cm","offer_id":44804863852588,"sku":"0M0CFBUI2C51","price":8950.0,"currency_code":"USD","in_stock":true},{"title":"Sandstone \/ 54cm","offer_id":44804863885356,"sku":"0M0CFBUI2C54","price":8950.0,"currency_code":"USD","in_stock":true},{"title":"Sandstone \/ 56cm","offer_id":44804863918124,"sku":"0M0CFBUI2C56","price":8950.0,"currency_code":"USD","in_stock":true},{"title":"Sandstone \/ 58cm","offer_id":44804863950892,"sku":"0M0CFBUI2C58","price":8950.0,"currency_code":"USD","in_stock":true},{"title":"Sandstone \/ 61cm","offer_id":44804863983660,"sku":"0M0CFBUI2C61","price":8950.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0608\/7684\/9196\/files\/CERVELO-CALEDONIA-5-ULTEGRA-DI2-8150-2027-FIVE-BLACK_56432bb0-c7b1-4aea-aa1f-a4dd0a97c5b1.jpg?v=1783620348"},{"product_id":"cervelo-caledonia-5-rival-axs-bike-7202","title":"Cervelo Caledonia-5 Rival AXS Bike","description":"\u003cdiv\u003e\n\u003cp\u003eThe \u003cstrong\u003eCervelo Caledonia-5 Rival AXS Bike\u003c\/strong\u003e is built for what Cervelo calls Big, Stupid Rides — ultra-distance, high-speed efforts where the road goes on longer than it probably should and you need a machine that can keep up without asking anything of you. This is not a compromise bike. It has the fit and handling geometry of a genuine endurance road bike, but the frame engineering and componentry of a race machine. Cervelo built the Caledonia-5 to go fast over long distances, and it shows in every decision they made.\u003c\/p\u003e\n\u003cp\u003eThe carbon frame carries forward everything that made the original Caledonia a favorite for endurance riders, then refines it. The seat stays are dropped — following the same approach Cervelo used on the Aspero gravel bike — which makes the rear triangle more vertically flexible and takes the edge off road chatter on rougher surfaces. At the same time, Cervelo stiffened the downtube relative to the previous generation, preserving the direct, responsive power transfer that riders expect from a Cervelo. You feel the difference: a frame that absorbs the road without going slack. Aero tube shaping and fully internal cable routing round out the package, reducing drag and keeping the front end exceptionally clean.\u003c\/p\u003e\n\u003cp\u003eNew to the Caledonia-5 is integrated in-frame storage — a design element borrowed from the P-Series triathlon bikes. The hatch sits in the downtube and holds a tube, a small multi-tool, and a CO2 canister. It's not enormous by design; this isn't luggage. It's emergency kit, stashed where you won't notice it until you need it. The hatch opens and closes with one hand even with gloves on. Tire clearance runs to 36mm, and every Caledonia-5 ships with fender mounts, making it genuinely capable of handling mixed road conditions and commuter use without modification.\u003c\/p\u003e\n\u003ch3\u003eDesign Benefits\u003c\/h3\u003e\n\u003col class=\"design_benefits\"\u003e\n\u003cli\u003e\n\u003cstrong\u003eWireless shifting with power data:\u003c\/strong\u003e SRAM Rival AXS delivers precise electronic shifting without cables to route or adjust, and the crankset includes an integrated power meter at this price — a meaningful value for riders who train with data.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReserve 42|49TA carbon wheels:\u003c\/strong\u003e The asymmetric depth pairing — 42mm front, 49mm rear — is a considered choice.
