What was recalled
In May of 2017, the U.S. Consumer Product Safety Commission (CPSC) announced a significant safety recall involving bicycle handlebar stems manufactured by Profile Design. This action targeted specific models of carbon-wrapped stems that were sold both individually as aftermarket parts and installed as original equipment on bicycles from several major brands. The recall is not broad or vague; it focuses on a precise product line known as the "Cobra S" series. These stems are distinctively black with the words "Profile Design" and "Cobra S" printed in white lettering along their surface. It is important to note that this recall applies exclusively to black stems of this specific design. Other colors or different models from Profile Design are not included in this notice.
The affected products were sold in seven different lengths, or sizes, to accommodate various rider preferences and bicycle geometries. These sizes include 60 mm, 70 mm, 80 mm, 90 mm, 100 mm, 110 mm, and 120 mm stems. The recall impacts bicycles from four specific manufacturers: Kestrel, Fuji, Jamis, and Scott. If you own a bicycle from one of these brands, particularly those manufactured between 2008 and 2010, it is worth checking the handlebar area to see if it matches the description above.
For owners of Kestrel bicycles, the recall covers several models from 2009 and 2010. In 2009, this includes the Talon SL Tri Ultegra, the Evoke SL, the Airfoil Pro SL, and the standard Talon SL. Moving into 2010, the affected Kestrel models are the Talon SL Tri-Ultegra, the Talon Tri-Force, the Airfoil Pro SL/Airfoil Pro SL (650c), the Talon Road SL, and the 4000 SL. Fuji bicycles from 2009 and 2010 are also affected. Specifically, the 2009 D-6 Pro and the 2010 D-6 Pro, as well as the 2010 D-6 Matt Reed model, may have been equipped with these recalled stems.
Jamis and Scott bicycles from this era are also part of the recall. The Jamis Xenith T2, specifically the 2010 model, is included. For Scott owners, the recall targets three specific Plasma models: the 2008 CR1 Plasma LTD (model number 209562), the 2009 Plasma Premium (model number 212052), and the 2010 Plasma Premium (model number 215722). If your bicycle falls into any of these categories, it is crucial to verify whether it contains the recalled black Cobra S stem. The recall was officially initiated on May 9, 2017, but because these bicycles were sold years prior, many may still be in use today. Checking your equipment now is a simple step that ensures your safety while riding.
The hazard, explained
At the heart of this recall is a silent but dangerous failure in one of the most critical components of your bicycle: the handlebar stem. This part acts as the bridge between your bike’s frame and the handlebars you hold onto for steering and control. When it works correctly, it transfers every turn, brake, and pedal stroke directly from your hands to the wheels. However, in the case of these specific Profile Design Cobra S carbon-wrapped stems, that connection can fail without warning due to corrosion.
The physical mechanism behind this hazard is insidious because it often happens from the inside out. These stems are constructed with a carbon fiber exterior wrapped around a metal core. Over time, moisture, road salt, and general environmental exposure can penetrate microscopic gaps in the protective wrap or at connection points. Once water reaches the internal metal components, it begins to corrode them. This corrosion weakens the structural integrity of the stem, effectively turning what should be a rigid, strong piece of equipment into something brittle and fragile. The problem is that this damage is rarely visible from the outside. The black carbon wrap may look pristine, but the inside could be severely compromised.
When the corrosion reaches a critical point, the stem can fracture suddenly under normal riding loads. This is not a gradual wear that you might feel as looseness over months; it is often a catastrophic break. Imagine leaning into a turn, hitting a small bump, or simply bearing your weight while climbing a hill. The stress on the stem increases, and if the internal metal has been eaten away by rust, it can snap instantly. There is typically no audible warning, such as a creaking noise, before the failure occurs.
The consequence of this breakage is immediate and severe loss of control. Because the handlebar stem connects your steering input to the front wheel, its sudden collapse means you lose all ability to steer or brake with that wheel. The bike may veer sharply into traffic, flip over the handlebars, or cause you to be thrown from the saddle. This explains why the CPSC has documented at least ten reports of these stems breaking, including one incident resulting in a rider injury. In those moments, there is little time to react. You are no longer riding a bicycle; you are falling from a height with an uncontrolled metal object moving beneath you.
This type of hazard is particularly frightening because it exploits the trust riders place in their equipment. We assume that high-end components like carbon fiber stems are durable and reliable. The reality, however, is that when the protective barrier fails and corrosion sets in, the component becomes a liability rather than an asset. Understanding this mechanism is crucial because it highlights why visual inspection alone is not enough to ensure your safety. If you have one of these stems, the risk is present even if the bike looks perfect on the surface.
Who is most at risk
The individuals most immediately affected by this recall are cyclists who own or ride specific high-performance road and triathlon bicycles manufactured between 2008 and 2010. This includes riders of Kestrel, Fuji, Jamis, and Scott models that were equipped with the Profile Design Cobra S carbon-wrapped black handlebar stems as original equipment. It is important to note that these stems were also sold individually, meaning a rider might have replaced their factory stem with this specific model at a later date. If you ride one of the listed models—such as the 2009 Kestrel Talon SL Tri Ultegra, the 2010 Fuji D-6 Pro, or the Scott Plasma Premium series—you are directly in the scope of this safety notice.
Beyond just owning the correct bicycle model, your risk level is determined by the specific physical characteristics of the recalled part. The hazard targets only the black stems marked with white "Profile Design" and "Cobra S" lettering. If you have a stem of a different color, or if it lacks these specific markings, it is not part of this recall. Furthermore, the corrosion issue that leads to structural failure can occur across all seven available lengths: 60 mm, 70 mm, 80 mm, 90 mm, 100 mm, 110 mm, and 120 mm. Therefore, the size of your stem does not exempt you from the risk; any length within this range is susceptible to the same corrosion mechanism.
In terms of physical vulnerability, cyclists who use these bicycles for high-speed road riding or competitive triathlons are at greater risk of severe injury. The recalled stems connect the handlebars to the bicycle frame, acting as a critical lever arm. When a stem corrodes and breaks under the stress of steering or braking, it can fail suddenly without warning. For a rider traveling at speed, losing control of the front end can result in an immediate crash. While the CPSC reports indicate that injuries have occurred, the severity often depends on the rider's speed, road conditions, and ability to react. Children or elderly riders are not specifically singled out by this recall as being uniquely vulnerable compared to adult athletes, but any cyclist relying on these bicycles for daily transportation or leisure is at risk because the failure mode is catastrophic loss of control rather than a gradual wear-out.
The risk is also heightened for those who may have ignored early warning signs. Corrosion is a progressive process. Riders who continue to use these stems after noticing any discoloration, pitting, or unusual texture on the black carbon surface are exposing themselves to an escalating danger. The fact that there have been reports of injuries underscores that this is not merely a theoretical flaw but a tangible threat to rider safety. Therefore, anyone who fits the description above—owning one of the specified bike models with the specific black Cobra S stem—must be considered at high risk until they take action.
How to tell if you have the recalled item
Before you take any action or contact customer service, it is essential to confirm whether your bicycle contains the specific components affected by this recall. Profile Design has issued a precise identification guide for the Cobra S carbon-wrapped black handlebar stems that pose a risk of corrosion and breakage. Because these parts are often integrated into high-performance bicycles sold years ago, visual inspection and checking model numbers are your most reliable methods for verification. Do not rely on guesswork; the recall is strictly limited to specific brands, models, and colors.
The first step in identification is to locate the handlebar stem itself, which is the component connecting your handlebars to the bicycle’s fork steerer tube. You need to look closely at the body of the stem for printed lettering. The recalled units will have "Profile Design" and "Cobra S" printed clearly in white text against the black background. This branding is a key identifier. It is important to note that this recall applies ONLY to black stems. If your bicycle has silver, red, or any other color stem, it is not part of this specific safety notice. Additionally, the stems were sold in seven distinct lengths: 60 mm, 70 mm, 80 mm, 90 mm, 100 mm, 110 mm, and 120 mm. While the length does not exclude a stem from the recall, knowing the size can help you cross-reference your purchase records or product manuals.
If you cannot read the markings clearly or if you are unsure whether the part is original equipment, you must check the make and model of your bicycle. This recall targets specific models from four manufacturers: Kestrel, Fuji, Jamis, and Scott. The affected items were sold individually or as original equipment on the following specific bicycle models:
- Kestrel Models: 2009 Talon SL Tri Ultegra, 2009 Evoke SL, 2009 Airfoil Pro SL, 2009 Talon SL; and 2010 Talon SL Tri-Ultegra, 2010 Talon Tri-Force, 2010 Airfoil Pro SL/Airfoil Pro SL (650c), 2010 Talon Road SL, and 2010 4000 SL.
- Fuji Models: 2009 D-6 Pro; and 2010 D-6 Pro and 2010 D-6 Matt Reed.
- Jamis Model: 2010 Xenith T2.
- Scott Models: 2008 CR1 Plasma LTD (model number 209562); 2009 Plasma Premium (model number 212052); and 2010 Plasma Premium (model number 215722).
If your bicycle matches one of the models listed above, particularly those from 2008 to 2010, there is a high probability it was equipped with the recalled stem. For Scott bicycles, verifying the specific model number stamped on the frame or provided in your documentation is crucial. Once you have confirmed that your bike has a black Profile Design Cobra S stem and falls within one of these model lists, you should treat it as part of the recall immediately. Do not wait for visible signs of corrosion to appear, as the structural integrity may already be compromised.
What to do — step by step
If you own one of the bicycles listed in this recall, your immediate priority is to ensure that the bicycle is no longer on the road or ready for a ride. The first and most critical step is to stop using the affected bicycles immediately. Do not attempt to ride them, even for short distances or at low speeds. The corrosion in the Profile Design Cobra S handlebar stems can cause them to break without warning, leading to a loss of control and a serious crash. By taking the bike off your property and storing it in a garage, shed, or basement, you eliminate the risk of an accident while you arrange for the remedy. This is not a step to delay; the hazard is present as long as the stem is installed on the frame. Once the bicycle has been secured safely out of use, you need to initiate the contact process with the manufacturer to obtain your free replacement parts. Profile Design has established specific channels for consumers to resolve this issue. You can reach their customer support team by calling their toll-free number at 888-800-5999.

What can happen if you ignore it
It is natural to want to keep riding your bicycle, especially if you are an avid cyclist who has invested time and money into maintaining your equipment. However, ignoring a recall notice for a critical component like a handlebar stem is not just a minor oversight; it is a direct invitation to significant physical danger. The core issue with the Profile Design Cobra S stems is not merely that they look worn or feel slightly loose. It is that the internal corrosion has compromised the structural integrity of the carbon-wrapped material in a way that is often invisible to the naked eye. When you continue to use these stems, you are effectively riding on borrowed time, relying on a component that has been fundamentally weakened by chemical degradation.
The consequences of this failure are immediate and severe. Because the handlebar stem connects your hands directly to the front wheel of the bicycle, any sudden breakage results in an instantaneous loss of steering control. Unlike a flat tire or a chain slip, which might allow you to coast to safety, a broken stem means the front end of your bike becomes unpredictable or completely unresponsive. You may find yourself jerking to one side, crashing into traffic, or falling directly over the handlebars. The CPSC reports confirm that this is not just a theoretical risk; there have already been at least ten documented cases of these stems corroding and breaking, including incidents where riders sustained injuries due to the sudden loss of control.
Consider the physics of what happens when a carbon-composite stem fails under load. Carbon fiber, while strong, can suffer from delamination or internal cracking when moisture penetrates the protective coating over time. As the stem corrodes, it loses its ability to distribute the force of your weight and the impact of road vibrations. When you hit a bump, brake hard, or lean into a turn, that weakened joint is likely to snap. This creates a "jackknife" effect where the front wheel turns independently of your input, leading to high-speed crashes at relatively low speeds. For competitive cyclists or those riding on busy roads, this margin for error does not exist.
Beyond the immediate risk of a crash, there is also the psychological toll and the potential for secondary injuries. A fall from a bicycle can result in fractures, concussions, road rash, and other serious trauma that requires extensive medical treatment and recovery time. By delaying your action, you are gambling with your health and safety. The remedy offered by Profile Design is free and straightforward, but the cost of ignoring it could be far higher than the inconvenience of a phone call. Do not wait for the stem to fail visibly or audibly; corrosion often progresses silently until catastrophic failure occurs. Your safety depends on recognizing that this defect is critical and acting before the worst-case scenario becomes your reality.
