Full Speed Ahead Recalls Gossamer Pro AGX+ Cranksets Sold on Bicycles Due to Fall and Injury Hazards

What was recalled

In the world of high-performance cycling, precision and reliability are not just preferences; they are the foundation of safety. On April 18, 2024, the U.S. Consumer Product Safety Commission (CPSC) announced a significant recall involving a specific component produced by Full Speed Ahead, a brand well-known for its lightweight and durable bicycle parts. This action was taken to address a critical manufacturing defect that could compromise the structural integrity of the bicycle’s drivetrain system under normal riding conditions.

The specific items subject to this recall are the Gossamer Pro AGX+ cranksets, identified by the model number CK-6037. It is important to understand exactly what you are looking for if you own a bicycle equipped with these components. These cranksets were not sold exclusively as standalone parts; they were integrated into complete bicycles sold by several major gravel and road bike manufacturers. If you own a gravel bike from brands such as Cannondale, Canyon, Marin, Haro, Fuji, or Pinarello, there is a possibility your bicycle came equipped with these recalled cranksets directly from the factory.

To determine if your bicycle is part of this recall, you must look closely at the components themselves. The presence of the "FSA Gossamer Pro" logo etched into the front of the crankarm is a primary visual indicator. However, visual identification alone is not enough to confirm whether your specific unit is affected. You must locate the model and serial numbers, which are stamped on the back of the bicycle’s crankarm, right next to the pedal threads. The recall applies strictly to units with serial numbers that begin with the codes B1, B2, or B3. Units with other serial number prefixes are not included in this safety action.

While the provided official record does not specify the exact total number of individual cranksets sold worldwide, it notes that the firm has received 277 reports of these crankarms loosening or detaching. This high volume of reports underscores the widespread nature of the potential issue across the various brands that incorporated these parts into their inventory. The defect poses a serious risk because the crank arms can loosen and detach from the crank spindle, which could lead to a sudden loss of control while riding, resulting in falls and potential injury.

If you own a bicycle from one of the mentioned brands, or if you purchased a Gossamer Pro AGX+ crankset separately, do not panic. The remedy is straightforward: consumers should immediately stop using the bicycles with the recalled cranksets and contact Full Speed Ahead for instructions on how to receive free dealer installation of a new replacement crankset. This recall highlights the importance of verifying component serial numbers, even on newer bikes, as manufacturing batches can vary.

The hazard, explained

To understand why this recall is necessary, it helps to look at the specific mechanical failure involved. The issue centers on the crank arms of the Gossamer Pro AGX+ crankset, which are the metal levers that connect your pedals to the bicycle’s chainring and drivetrain. Under normal circumstances, these components are designed to transfer the force you apply while pedaling directly into forward motion. However, in this specific case, the connection point between the crank arm and the central spindle can loosen or detach entirely. This is not a minor wobble; it is a structural failure of the interface that holds your foot’s leverage point to the bike.

When these crank arms loosen, they create an immediate and unpredictable instability. You might first notice a clicking sound or a slight loss of resistance while pedaling, but the situation can escalate rapidly. If the crank arm detaches completely while you are riding—especially at speed or during a critical maneuver like climbing a hill or navigating a turn—the pedal will drop away from under your foot. This sudden loss of control is the primary mechanism of injury here.

The physical harm that results from this failure is typically direct and severe. Because cyclists rely on balance and momentum, losing a pedal unexpectedly can cause the rider to be thrown from the bicycle. The fall itself poses significant risks, including road rash, fractures, sprains, and head injuries if a helmet is not worn or fails to provide adequate protection. Furthermore, the detached crank arm or pedal can become a secondary hazard, potentially striking other riders, pedestrians, or causing the cyclist to lose control in a way that leads to collisions with vehicles or fixed objects.

It is important to note that this is not merely a theoretical risk. The manufacturer has documented 277 reports of these crank arms loosening or detaching, confirming that the failure mode is active and recurring. While no injuries have been officially reported to date, the potential for serious harm is high because the failure occurs during dynamic movement. The force exerted on these components by an average adult rider can be substantial, meaning that once the internal locking mechanism fails, it is unlikely to recover on its own. The risk increases with usage, as vibration and stress cycles can accelerate the loosening process. Therefore, treating this as a critical safety failure rather than a simple maintenance issue is essential for your wellbeing.

Who is most at risk

The primary group facing immediate danger in this recall consists of owners and riders of high-performance gravel bicycles equipped with the specific Full Speed Ahead Gossamer Pro AGX+ cranksets. This includes bikes from prominent manufacturers such as Cannondale, Canyon, Marin, Haro, Fuji, and Pinarello. These are not casual commuter bikes; they are precision-engineered machines designed for rigorous off-road and mixed-terrain riding. The riders who benefit most from the safety of these components are those who engage in demanding activities like gravel grinding, mountain biking, or long-distance touring. Because these cranksets were sold both as standalone parts for upgrades and installed directly on new bicycles, the risk spans a wide demographic of cycling enthusiasts who may have purchased their gear recently or even months ago without realizing the potential flaw.

While no injuries have been reported to date, the nature of the hazard—crank arms loosening or detaching while in motion—creates a scenario where any rider is vulnerable. However, certain individuals are at greater risk due to the physical demands of gravel cycling. Cyclists who frequently stand up on their pedals to climb hills, sprint out of corners, or navigate rough terrain place significantly higher torque loads on the crankset. This mechanical stress is exactly what can cause a loose crank arm to fail completely. Riders with less upper body strength or those who rely heavily on standing positions for traction may find themselves disproportionately affected if the connection fails during a critical moment of power transfer.

Children and teenagers who have inherited or been gifted these high-end bikes are also in the risk category, though their vulnerability stems from different factors. Younger riders often lack the experience to recognize early warning signs, such as unusual clicking noises or slight wobbles in the pedal assembly. They may continue riding, unaware that the component is deteriorating, until a sudden detachment occurs. Furthermore, because gravel biking involves unpredictable surfaces like loose gravel, rocks, and roots, a sudden loss of drive can cause the bike to lurch violently. A rider with less developed balance or reaction time may not be able to correct the bike’s trajectory quickly enough, leading to a fall onto hard or uneven ground.

Elderly riders, who may also own these sophisticated bicycles for fitness or recreation, face heightened consequences from such failures. A fall at speed on gravel terrain can result in severe injuries, including fractures or head trauma, which are particularly dangerous for older adults with reduced bone density or slower recovery times. Additionally, the sudden loss of control can induce panic, leading to secondary accidents where the rider loses balance in a way that causes more harm than the initial mechanical failure would have alone. It is crucial for all users, regardless of age or skill level, to understand that the integrity of the connection between the crank arm and the spindle is the foundation of safe riding. When that link breaks, the rider’s safety depends entirely on their ability to stop safely in a chaotic situation, which is much harder when you have no power to brake or steer effectively.

Ultimately, the risk is not limited to professional athletes. It extends to weekend warriors, fitness enthusiasts, and anyone who values their bike for daily transportation or leisure. The recall affects serial numbers beginning with B1, B2, or B3, which means even if you are not a "pro" rider, if your bike falls within this production window, you are part of the at-risk group. The calm approach here is to check your serial number immediately. Ignoring the potential for failure because you feel confident in your riding skills is a gamble with your physical well-being. The goal is to ensure that every rider, from the competitive racer to the casual weekend explorer, can enjoy the ride without worrying about their bike’s most critical mechanical connection giving way beneath them.

How to tell if you have the recalled item

Identifying whether your bicycle is equipped with a recalled crankset requires a close look at both the component itself and the broader context of how it was sold. Because these parts were distributed in two distinct ways—sold individually to bike shops or directly to consumers, and installed on new bikes by major manufacturers—you need to check multiple points of information to be certain. The primary suspect is the Full Speed Ahead Gossamer Pro AGX+ crankset, specifically model CK-6037. If you are unsure whether your bike has this specific part, start by examining the crankarms directly.

The most reliable way to confirm the model is to look at the physical hardware on your bicycle. Cranksets are located in the center of your bike, connecting your pedals to the frame. Turn your attention to the front face of the crankarm (the part that sticks out toward the front wheel). You should see specific etching or engraving that reads "FSA Gossamer Pro." This branding is a key identifier for this group of products. However, looking at the brand name alone is not enough, as Full Speed Ahead makes several different models. You must verify the specific model number to ensure it falls under this recall.

To find the exact model and serial numbers, flip the crankarm around so you are looking at the back side, near where the pedal screws in. The model number CK-6037 and a unique serial number will be stamped or etched in this area, right next to the pedal threads. This is the critical piece of data that determines your eligibility for the remedy. The recall applies only to units with serial numbers that begin with B1, B2, or B3. If your serial number starts with any other letters or digits, your specific crankset is not part of this safety notice.

If you cannot easily read the etching or if you are buying a used bike and don’t have immediate access to the tools needed to inspect it closely, look at the brand of the bicycle itself. These recalled Gossamer Pro AGX+ cranksets were sold on gravel bikes from several well-known brands, including Cannondale, Canyon, Marin, Haro, Fuji, and Pinarello. If your bike is one of these brands and was purchased around the time of this recall (April 2024), it is highly probable it came equipped with the affected part. Always double-check the serial number on the crank to be absolutely sure, as manufacturers sometimes mix components across different production runs.

Finally, consider how you acquired the bike or the parts. If you bought a new gravel bike from any of the aforementioned brands recently, or if you purchased a standalone crankset directly from Full Speed Ahead or an authorized dealer, you should perform this inspection immediately. The recall affects units sold separately and those pre-installed on bicycles. There is no price range listed in the official CPSC record that can help identify the item, so do not rely on cost as an indicator. Your safety depends on verifying the physical labels on the crankarm, specifically looking for "FSA Gossamer Pro" and a serial number starting with B1, B2, or B3.

What can happen if you ignore it

It is completely understandable why you might hesitate to stop riding your bike right away. Perhaps you have a long commute ahead of you, a weekend trip planned, or simply enjoy the specific feel of that crankset. However, ignoring this recall is not a minor inconvenience; it is a significant safety gamble with potentially severe physical consequences. The core issue here is mechanical failure under load. Bicycle crankarms are not static parts; they endure immense twisting forces every time you pedal, especially when standing up to sprint or climbing a hill. When the crankarm loosens or detaches from the spindle, that structural integrity vanishes instantly. This is not a slow wear-and-tear process that gives you plenty of warning; it is a sudden loss of control.

The most immediate danger is an uncontrolled fall. If the crankarm detaches while you are pedaling, your foot may be pulled out from under you, or the bike may lurch violently to one side as the balance shifts. This can cause you to crash onto the pavement, into traffic, or against obstacles. Even if you manage to keep your balance for a split second, the shock of the failure can startle you, leading to secondary falls or loss of control over the handlebars. For cyclists, especially those riding on gravel roads where traction is less predictable than on smooth asphalt, this kind of sudden mechanical failure is particularly dangerous because there is often little time to react.

The injuries associated with such falls can range from minor scrapes and bruises to serious trauma. While the company has reported 277 instances of crankarms loosening or detaching without confirmed injuries so far, the absence of reported injuries does not mean the risk is low. It simply means that, up to this point, no one has been hurt in these specific cases. However, mechanical failures of this nature are unpredictable. A fall from a moving bicycle can easily result in fractures, head injuries, or sprains, depending on where you land and how fast you were going. The potential for harm is real and present, regardless of current statistics.

Furthermore, continuing to use the recalled crankset puts your entire cycling experience at risk. A sudden detachment can damage other components of your bike, such as the chainring or the bottom bracket shell, leading to costly repairs that could have been avoided. More importantly, it undermines your confidence in your equipment. You deserve to ride with peace of mind, knowing that your bike is safe and reliable. By acting now, you protect yourself from physical harm and ensure that your next ride is enjoyable, not dangerous. Do not wait for a worst-case scenario to become reality; the remedy is free and straightforward, so take advantage of it today.
