Advanced tools can be purchased without any training or experience.


The disparity in training and certification within the bike fitting industry is another factor to consider. Not all bike fitters undergo the same rigorous training programs or acquire certifications from reputable organizations. Choosing a fitter with varied experience and training provides assurance regarding their commitment to professional standards and ongoing education.  Even if all bike fitters received the same training, do all medical doctors provide the same level of effectiveness? Bike fitting is similar in this aspect, so gleaning information about the bike fitter and their experience is paramount to a great fit.


This discussion is not intended as a critique of dedicated and skilled bike fitters. Instead, it sheds light on the misconception perpetuated by some establishments that believe a bike fit can be performed by anyone, regardless of their experience, expertise, training, tools, and talent.


In the experience of this blog writer, the most passionate fitters who seek to constantly improve their skills and outcomes provide the most exceptional services.


Myth 7: My Friend fit me and I Watched Bike Fitting Videos on YouTube, so I'm Good



Myth 7: Image of My friend fit me and I watched bike fitting videos on Youtube so I'm good


You’ve likely heard this one before, “opinions are like anuses, everyone has one.” That doesn’t mean that they are right for you. The myth that a friend or online tutorials can substitute for a professional bike fit overlooks the intricacies involved in optimizing a bike setup for an individual rider. While the intentions of friends and online resources are commendable, achieving the level of precision necessary for an optimal fit demands a trained eye, experience, and a comprehensive understanding of biomechanics.


A friend's assistance and YouTube tutorials may offer general guidelines, but they often lack the personalized assessment required for an effective bike fit. Every cyclist is unique, with distinct body proportions, flexibility, and riding preferences. A professional bike fitter should go beyond generic advice (see Myth 8), considering these individual factors to create a customized fit that enhances comfort, efficiency, and overall cycling experience.


Moreover, the dynamics of the fitting process involve real-time adjustments and observations that cannot be replicated through online tutorials or second-hand guidance. A true professional bike fit typically includes an evaluation of range of motion and functional movement, assessments of saddle height, handlebar reach, pedal alignment, crank arm length, and other nuanced adjustments that contribute to an optimal riding position. With 90+ Cyclings fittings, after every adjustment, the data and biomechanical range of motion are retested and adjustments continue until you are dialed in. Relying solely on generalized information may result in overlooking crucial details, leading to discomfort and potential long-term issues.


The belief that a friend or online guidance is sufficient may also neglect the evolving nature of a cyclist's body and riding style. Professional bike fitters understand how changes in fitness, flexibility, or riding goals can impact the ideal bike setup. Their expertise enables them to anticipate and adapt the fit accordingly, ensuring that your bike remains tailored to your evolving needs.


Myth 6: Stock Bikes Fit Everyone



The myth that stock bikes fit everyone stems from a common misconception that standard bike sizes and configurations cater to a wide range of body types and riding styles. In reality, riders are as diverse as their bikes should be, and assuming that a stock bike accommodates every individual overlooks critical factors influencing comfort and performance.


The misconception that stock bikes fit everyone is reminiscent of a historical dilemma (cataloged by Todd Rose in the Toronto Star) faced by the U.S. Air Force in the 1940s. Lt. Gilbert Daniels, a researcher, aimed to create an average cockpit size for pilots based on 10 dimensions measured on 4063 selected pilots of a presumed "average" height. Astonishingly, not a single pilot measured in the average range on all 10 dimensions. In fact, only 3.5% of pilots fell within the average range on just three dimensions, such as height, arm length, and leg length. Lt. Daniels' groundbreaking findings shattered the notion of a universal average, emphasizing the need for highly customized cockpits for each individual.


Similarly, the sizing of stock bikes is often determined by the law of averages, with brands reviewing and plotting the dimensions of 7-10 other brands to create their bike sizing geometry within a "normal" curve. While bikes come with adjustable components, these adjustments based on sizing significantly impact the ride experience. Just as Lt. Daniels concluded for cockpits, the story underscores that there is no one-size-fits-all in the cycling world. The importance of a personalized bike fit prior to purchase becomes evident, ensuring that the bike aligns with the unique dimensions, biomechanics, and preferences of the individual rider. Recognizing the individuality of cyclists and the limitations of standardized sizing is crucial for a truly comfortable and optimized cycling experience.


Beyond body dimensions, every cyclist has a unique set of biomechanics, proportions, and preferences. Stock bikes, designed with generalities in mind, might not align with the specific needs of an individual rider. A personalized bike fit becomes paramount in addressing these unique characteristics, ensuring that the rider is harmoniously connected with their bike. This customization is not just about achieving an optimal riding position; it's about preventing discomfort, enhancing efficiency, and reducing the risk of potential injuries.


Moreover, stock bikes may come with generic and often cheap components, including saddles, handlebars, and stems, which may not suit every rider. These components play a crucial role in comfort, performance, and control. A personalized bike fit considers these elements, ensuring that the rider interacts seamlessly with their bike, preventing discomfort and promoting optimal handling and efficiency.

The notion that you should only consider a bike fit when pain or issues arise neglects the proactive advantages that come with a customized bike fit. Pain is often a silent companion, subtly affecting your cycling experience until your body reaches a tipping point. It's much like a faucet that drips. It doesn't cause damage at first but over time you'll notice stains and even indentations in your sink. By waiting for symptoms to emerge, you may have missed out on the enhanced cycling experience that a proactive bike fit can provide.


Cycling, particularly with an ill-fitted bike, can lead to overuse injuries and discomfort that accumulate gradually. The body often adapts until it can no longer compensate, resulting in pain or discomfort that seems to emerge suddenly. A proactive bike fit addresses potential issues before they become pronounced, unlocking more power and comfort, and reducing the likelihood of overuse injuries.


Imagine the difference it would make to your cycling experience if you could tap into more power, pedal with increased comfort, and significantly lower the risk of overuse injuries. Seeking a bike fit before symptoms arise allows you to optimize your riding position, ensuring that your biomechanics are in harmony with your bike. It's not just about mitigating existing pain; it's about unlocking the full potential of your cycling performance and maintaining a sustainable and enjoyable relationship with your bike over the long term.

The misconception that bike shoes don't matter overlooks the pivotal role they play in ensuring a comfortable and efficient cycling experience. The reality is that the right pair of cycling shoes can greatly enhance your performance on the bike, prevent discomfort, and contribute to a more enjoyable ride.


Cycling shoes are not mere foot coverings; they serve as a direct link between your body and the bike. Properly fitted and designed cycling shoes play a pivotal role in optimizing power transfer from your legs to the pedals. This efficient power transfer is not only beneficial for competitive cyclists seeking to gain an edge but is equally crucial for recreational riders aiming to enhance their overall efficiency on the bike.


Foot stability during the pedaling motion is another critical aspect addressed by the right pair of cycling shoes. Ill-fitting, inadequate, or improperly set up cycling shoes can lead to discomfort, hotspots, and even numbness. Recognizing the unique anatomy of each cyclist's feet, a professional bike fit considers the design and fit of cycling shoes, recommending pairs that provide the necessary support and comfort for individual riding styles.  This is especially critical considering the complex anatomy of the foot, including three key arches: the transverse arch, medial longitudinal arch, and anterior longitudinal arch.


Myth 2: All Bike Seats Hurt

The widespread myth that all bike seats inherently lead to discomfort is rooted in a misunderstanding of the intricate factors involved in saddle selection (we dove into major saddle myths in a previous article). It's important to clarify that not all saddles are uncomfortable; rather, the key lies in choosing a saddle that aligns with your individual riding style, body geometry, and the overall fit of your bike. 


Bike seats are unequivocally not one-size-fits-all. The diverse anatomies of cyclists require a wide array of saddle options, each designed with specific shapes, widths, and cushioning. Acknowledging this diversity, a professional bike fit takes into account your unique pelvic structure and riding style, guiding you toward a saddle that provides the necessary support in precisely the right places. This personalized approach is integral to fostering comfort and preventing discomfort during rides.


The mismatch between a rider's style and the saddle's design is a primary contributor to saddle discomfort. Different riding styles, whether it's an aggressive road cycling posture or a more upright commuter position, require specific saddle shapes and features. It’s imperative to have your riding dynamics carefully assessed by a professional bike fitter, ensuring that the selected saddle supports your preferred position, thereby minimizing pressure points and discomfort.


Discomfort often arises from pressure points on the pubis rami, perineum, or sit bones. A bike fit utilizing pressure mapping analyzes your riding position, identifies painful pressure points, and makes necessary adjustments to distribute pressure evenly. This meticulous attention to detail minimizes the risk of soreness or numbness, contributing not only to enjoyable rides but also to your overall well-being.

Contrary to popular belief, the necessity for a bike fit isn't confined to those who already possess a bike. In fact, opting for a professional bike fit before making a purchase can be a strategic move with various benefits. This approach ensures that you select a bike that not only suits your personal preferences but also aligns seamlessly with your body's unique geometry.


Picture this scenario: you invest in a bike only to discover later that it doesn't quite match your body proportions or riding style.  Now what? Can you return or exchange the bike or do you find yourself with limited options after a significant investment? A pre-purchase bike fit serves as a proactive measure, guiding you towards bikes that are not only the right size but also complement your biomechanics. This foresight saves you from potential costly mistakes and the inconvenience of having to modify or replace costly components after the initial purchase. In addition, the modifications or replaced components may not fully provide you with the best experience.


Beyond merely determining the correct frame size, a professional bike fit before purchase offers insights into the ideal bike geometry and type. It helps you make an informed decision, ensuring that the bike you choose provides a comfortable and efficient ride right from the outset. Additionally, a pre-purchase fit doesn't only stop at adjusting existing bikes; it also provides valuable recommendations for components such as saddles, handlebars, stems, pedals, and other accessories that enhance your overall riding experience.


While it's true that adjustments can be made post-purchase, beginning with a professional bike fit is a time-saving approach. Instead of undergoing a trial-and-error process to find the optimal setup, a pre-purchase fit streamlines decision-making, allowing you to hit the road with confidence immediately. Moreover, riding a bike that isn't properly fitted to your body can lead to discomfort and potential injuries. Addressing these concerns before purchasing a bike minimizes the risk of developing issues such as knee pain, backache, or numbness during your rides.
