Cervélo USA Recalls R5 and Caledonia-5 Bicycles and Cervélo Replacement Stems Due to Fall Hazard

What was recalled

If you own a high-performance bicycle from Cervélo USA, specifically models manufactured for the 2022 model year, it is crucial to understand exactly which items are part of this safety recall. The U.S. Consumer Product Safety Commission (CPSC) has announced that Cervélo is voluntarily recalling certain R5 and Caledonia-5 bicycles, along with specific replacement stems. This action was taken on September 15, 2022, to address a critical mechanical failure that could compromise the safety of the rider. The recall does not cover all Cervélo products; it is strictly limited to a defined list of models and components that were produced during this specific timeframe.

The primary items affected are the Model Year 2022 Cervélo R5 and Caledonia-5 bicycles. These are premium road bikes, known for their speed and engineering, but they share a common vulnerability in this recall: the handlebars can slip within the stem. Additionally, the recall includes the Cervélo ST31 LT replacement stems themselves. These replacement stems were sold exclusively in black and were intended to be installed on these frames to hold the handlebars in place. If you purchased a bicycle that came with one of these stems from the factory, or if you bought the ST31 LT stem separately to upgrade your existing bike, it falls under this notice.

To help you identify whether your specific unit is included, Cervélo has provided a detailed list of the affected colors and specifications. The recall applies only to the following configurations of the R5 model: the Dura Ace Di2 in Five Black; the Red eTap AXS in Five Black; the Force eTap AXS in both Lime/Black and Five Black; and the Ultegra Di2 in both Lime/Black and Five Black. For those who purchased framesets rather than complete bikes, the R5 Frameset is included in all three of its color options: Five Black, Lime/Black, and the Jumbo-Visma Replica livery.

The Caledonia-5 models are also affected, specifically those equipped with Dura Ace Di2 in Oasis, Red eTap AXS in Five Black, and Framesets in Five Black, Aqua Pearl, or Oasis. Finally, the standalone Cervélo ST31 LT Replacement Stem is recalled, regardless of which bicycle it might be attached to, provided it is the black version sold during this period. The brand name "Cervélo" and the model names "R5" or "Caledonia-5" are printed directly on the bicycle's frame, serving as your primary visual confirmation. If your bike matches any of these descriptions, it is part of the recall, and you should take immediate steps to have it inspected and repaired.

The hazard, explained

At the heart of this recall is a critical failure in the connection between your handlebars and the bicycle’s frame. Specifically, the issue lies within the stem—the short component that clamps onto the bike’s steerer tube and holds your handlebars in place. In the affected Cervélo R5 and Caledonia-5 bicycles, as well as the standalone ST31 LT replacement stems, the faceplate (the part of the stem that tightens directly over the handlebar) does not secure the bars with sufficient friction or alignment stability. Under normal riding conditions, this might feel fine. However, during active use—whether you are sprinting up a hill, braking hard for a turn, or riding over rough pavement—the forces exerted on the handlebars can cause them to slip slightly within the stem’s clamping mechanism.

Why does this matter? Because your handlebars are your primary point of contact with the bike. They dictate your steering, your balance, and your ability to control speed through braking. When the handlebars shift position unexpectedly, you lose that precise control instantly. Imagine turning a corner and feeling the bars twist away from your grip, or hitting a bump and having the front end of the bike wander unpredictably. This sudden loss of alignment means the bicycle no longer responds to your inputs as expected. You might try to correct your line, but the bike is now moving in a different direction than your body anticipates.

This mechanical slippage leads directly to the fall hazard identified by the Consumer Product Safety Commission (CPSC). The recall notice confirms that there have been 13 reported instances of this handlebar slippage. While most reports may not have resulted in severe harm, one injury has already occurred due to a rider losing control and falling. In cycling, falls at even moderate speeds can result in significant injuries, including fractures, road rash, or head trauma, especially if the rider is thrown off balance unexpectedly. The danger is compounded because this is a high-performance bicycle designed for speed; the faster you are going, the more violent the loss of control becomes when the steering geometry shifts without warning.

It is important to understand that this is not necessarily a case of the stem breaking or snapping in half. Instead, it is a subtle but dangerous lack of clamping integrity. The handlebars can rotate or slide within the stem’s faceplate under load. This means the defect might not be visible when you are standing still next to your bike. You cannot simply look at the stem and see if it is “loose.” The problem manifests only under the dynamic pressure of riding, making it a silent hazard until it is too late to react safely. That is why immediate cessation of use is the only safe course of action.

Who is most at risk

When we talk about who is "most at risk" in a product recall, we are really looking at two distinct groups: the people who physically own or operate the recalled item, and the individuals whose bodies may be more susceptible to injury if that hazard materializes. In this specific case involving Cervélo bicycles and replacement stems, the primary group at immediate risk consists of owners of Model Year 2022 Cervélo R5 and Caledonia-5 bicycles, as well as anyone who has installed a black ST31 LT replacement stem on their bike. These are not casual, neighborhood cruiser bikes; they are high-performance machines designed for speed and precision. The riders using these models are typically engaged in serious road cycling, often at significant speeds or on challenging terrain where split-second control is essential.

The mechanical failure described here—handlebars slipping within the stem—is particularly dangerous because it removes the rider’s ability to steer, brake, or balance without warning. This makes the physical condition and riding style of the user critical factors in determining risk level. Cyclists who ride aggressively, tackle steep descents, or navigate busy traffic are at heightened risk because the consequences of sudden loss of control are severe. At high speeds, a slipping handlebar can cause an immediate and uncontrolled crash, leaving little time for the rider to react safely.

While the recall does not exclude any age group, certain individuals may face greater vulnerability due to physiological factors. Older adults, in particular, often have reduced bone density and slower reflex times. A fall that might result in a minor scrape or bruise for a younger, more agile rider could lead to serious fractures or long-term mobility issues for an older cyclist. Similarly, individuals with pre-existing balance issues or those recovering from previous injuries may find it harder to stabilize themselves if the bike suddenly becomes unmanageable.

It is also important to consider that these bicycles are often used by enthusiasts who ride alone or in small groups far from immediate medical assistance. The isolation of long-distance rides can exacerbate the severity of an incident, as help may not be readily available. Therefore, the risk is not just about the mechanical failure itself, but about the context in which it occurs—speed, terrain, and rider physiology all converge to make this a serious concern for anyone who owns or uses these specific Cervélo models. Recognizing that you fall into one of these higher-risk categories should serve as a strong motivation to act quickly on the recall remedy.

How to tell if you have the recalled item

If you own a Cervélo bicycle or a replacement stem, determining whether your specific equipment is part of this recall requires careful attention to detail. The Consumer Product Safety Commission (CPSC) has identified that only certain models manufactured in 2022 are affected. To confirm if your bike is included, start by looking at the frame itself. You need to verify two key pieces of information: the model name and the year of manufacture. The recall specifically targets Model Year 2022 Cervélo R5 and Caledonia-5 bicycles. Additionally, the recall extends to Cervélo ST31 LT replacement stems, which were sold separately. If your bike is not one of these specific models or if it was manufactured in a different year, it is likely not part of this particular safety notice.

The easiest way to identify the model is to look for printed text on the bicycle's frame. Both "Cervélo" and the model name ("R5" or "Caledonia-5") should be clearly printed on the frame. For those who have purchased replacement stems rather than a complete bike, identification is slightly different. The recalled ST31 LT replacement stems were sold exclusively in black. If you have a stem that is not black, it is not part of this recall. However, if you do have a black stem, you must verify the model number to ensure it is the ST31 LT.

For bicycle owners, the color and specific configuration (SKU) are critical for identification because not all R5 or Caledonia-5 bikes from 2022 are recalled. The recall includes bicycles and framesets in specific colors. For the R5 model, the affected configurations include the Dura Ace Di2 in Five Black, the Red eTap AXS in Five Black, the Force eTap AXS in Lime/Black, the Force eTap AXS in Five Black, the Ultegra Di2 in Lime/Black, and the Ultegra Di2 in Five Black. Additionally, R5 Framesets in Five Black, Lime/Black, and Jumbo-Visma Replica colors are included. For the Caledonia-5 model, the recall covers the Dura Ace Di2 in Oasis, the Red eTap AXS in Five Black, Framesets in Five Black, Framesets in Aqua Pearl, and Framesets in Oasis. If your bike’s color or component group does not match these specific descriptions, it is likely safe from this particular defect.

If you are unsure about your bike's status after checking the frame and colors, do not guess. The safest approach is to contact Cervélo directly using the toll-free number 833-416-8605 or by emailing ST31LTRecallSupport@cervelo.com.

What to do — step by step

Your refund, repair, or replacement options

If you have identified that your bicycle or stem is part of this recall, the good news is that Cervélo has established a straightforward and cost-free remedy to address the safety concern. It is important to understand immediately that there is no option for a cash refund in this specific recall. Instead, the manufacturer’s commitment is to provide a free repair. This repair is designed to eliminate the fall hazard by replacing the faceplate on the affected components. The company has taken this step because they recognize that while the risk of losing control is serious, it can be effectively mitigated through proper mechanical correction rather than requiring you to purchase an entirely new bicycle or stem.

To initiate this process, you must not attempt to perform the repair yourself or send the item directly to Cervélo’s headquarters. The remedy is structured so that you contact your authorized Cervélo dealer. These dealers are equipped to handle the recall procedures and will arrange for the necessary parts and labor at no charge to you. If you do not know which dealer is authorized, you can locate one using the store locator tool available on the Cervélo website. This step is crucial because it ensures that the repair is performed by technicians who are trained in Cervélo’s specific assembly standards, guaranteeing that the new faceplate is installed correctly and safely.

If you are unable to reach a dealer or prefer to contact the manufacturer directly for more information, Cervélo has opened dedicated support channels. You can call their toll-free number at 833-416-8605. It is helpful to note that this line is open from 10 a.m. to 5 p.m. Pacific Time, Monday through Friday. For those who prefer written communication or need to send documentation, you can email ST31LTRecallSupport@cervelo.com. Additionally, all details regarding the recall, including direct links to dealer locators and further instructions, are posted on their official product recalls page at https://www.cervelo.com/product-recalls. You can also navigate to the "Recalls" section on their main website for consolidated information.

The condition of this remedy is that you must stop using the recalled items immediately. Do not ride the bicycle or use the replacement stem until the faceplate has been replaced by a professional. The recall applies specifically to Model Year 2022 Cervélo R5 and Caledonia-5 bicycles, as well as the ST31 LT replacement stems sold in black. By following these steps and utilizing the provided contact methods, you ensure that your safety is prioritized without any financial burden. Remember, this free repair is your primary option, and it is fully supported by both the manufacturer and their authorized dealer network.

What can happen if you ignore it

When a recall notice arrives, it is natural to feel overwhelmed or to think that the risk might be theoretical. However, in the case of the Cervélo R5 and Caledonia-5 bicycles, as well as the specific ST31 LT replacement stems, the danger is immediate and mechanical. The core issue is that the handlebars can slip within the stem clamp. This is not a minor wobble; it is a complete loss of steering authority at the most critical moment.

If you continue to ride these bicycles or use the recalled stems without having them repaired, you are essentially riding with a broken safety mechanism. The design flaw means that the connection between your hands and the front wheel is unreliable. Under normal riding conditions, this might feel fine for a short time. But during any sudden maneuver—such as swerving to avoid an obstacle, braking hard on a descent, or even hitting a small bump—the handlebars can shift unexpectedly. This slippage causes the front wheel to turn in a direction you did not intend, leading to an immediate and uncontrollable fall.

This is not just a hypothetical scenario. According to the Consumer Product Safety Commission (CPSC), Cervélo has already received 13 reports of this handlebar slippage occurring in the wild. More alarmingly, one injury has been confirmed as a direct result of this defect. While we do not know the full extent of other potential incidents that may have gone unreported, the fact that injuries have already occurred proves that the hazard is active and dangerous. Ignoring the recall does not make the problem disappear; it only leaves you vulnerable to becoming the next statistic.

The consequences of ignoring this recall extend beyond the immediate physical injury from a fall. A loss of control at speed can lead to severe trauma, including fractures, head injuries, or road rash. Furthermore, if you are riding in traffic, an unexpected fall puts not only you but also other cyclists and motorists at risk. You might be forced into the path of a car or cause a chain-reaction accident. The peace of mind that comes with knowing your bike is safe is worth far more than the time it takes to schedule a repair.

Finally, consider the financial and legal implications. By ignoring the recall, you are choosing to bear the full cost of any potential future injuries or damages yourself. Cervélo is offering a free repair to replace the faceplate, which resolves the safety issue entirely. If you choose not to take advantage of this remedy, you are accepting the risk of falling while riding a product that is known to be defective. Do not wait for a worst-case scenario to convince you to act. The safest choice is always to stop using the item and seek the free repair immediately.

Staying safe: broader tips

While this specific recall addresses a critical defect in certain Cervélo bicycle components, the underlying principle applies to all high-performance equipment: regular, intentional inspection is your first line of defense against mechanical failure. Bicycles, particularly those designed for racing or rigorous endurance riding like the R5 and Caledonia-5 models, endure immense stress on their steering systems. The handlebar-stem interface is a primary pivot point where torque and vibration can gradually loosen connections over time. To stay safe, you should develop a habit of checking your bike’s critical fasteners before every major ride. This does not mean just glancing at them; it means using the correct tools to verify that bolts are tightened to the manufacturer’s specified torque values. Many modern carbon fiber components require specific torque settings to prevent damage while ensuring security. If you do not have a torque wrench, consider visiting a local shop for a quick check-up, as overtightening can crack materials just as surely as undertightening can allow slippage.

Beyond mechanical checks, staying informed about product safety is an essential part of being a responsible consumer. Manufacturers and regulatory agencies like the Consumer Product Safety Commission (CPSC) issue recalls when they identify potential hazards that could lead to injury. These alerts are not merely bureaucratic notices; they are vital updates that can prevent serious accidents. We recommend subscribing to email alerts from the CPSC or creating a free account on their website to receive notifications relevant to your household. Additionally, consider registering your high-value purchases directly with the manufacturers at the time of purchase. This practice ensures that if a safety issue arises, you will be contacted directly with instructions on how to resolve it, rather than having to discover the problem through a news search or after an incident has occurred.

Finally, foster a culture of proactive maintenance within your household. Whether it is checking smoke detector batteries, inspecting playground equipment for rust and sharp edges, or examining bicycle stems for hairline cracks around bolt holes, small preventive actions yield significant safety dividends. Encourage family members to report any unusual noises, looseness, or performance changes in their gear immediately. Do not dismiss minor issues as "normal wear." In the context of cycling, a handlebar that feels even slightly unstable is a warning sign that should never be ignored. By combining diligent personal inspection with active engagement with official recall databases, you transform passive ownership into active safety management, ensuring that your equipment remains a source of joy and exercise rather than risk.
