Here at SSC we applaud and encourage you to throw money at the problem – looking to buy watts via the latest aero dream build or upgrading components.
However, a (near) universal truth that we run into on a daily basis is just how many cyclists neglect the importance of bike fitting, and realize that having a proper bike fit is one of the most important aspects of enhancing both performance and comfort when cycling.
Every cyclist’s body is different, and so are their riding goals. Some cyclists prioritize endurance, while others focus on speed. Bike fitting takes these individual factors into account. A crit racer may need an aggressive, aerodynamic fit, while a novice cyclist will benefit from a more upright, relaxed position.
For those with specific anatomical considerations—such as leg length discrepancies, joint issues, or previous injuries—bike fitting can be an especially critical process. A professional fitter can make adjustments that account for these, ensuring that your bike is set up to meet your body’s unique needs.
Bottom line: Bike fitting can make or break your cycling experience and in terms of low hanging fruit, often returns the biggest bang for your buck.
In this blog post, we’ll explore the essential benefits of bike fitting, covering comfort, performance, injury prevention, and long-term health.
What Is Bike Fitting?
Bike fitting is the process of adjusting your bicycle to match your body’s unique proportions, riding style, and goals. It involves configuring aspects such as saddle height, handlebar position, crank length, and pedal alignment to ensure your body and bike work together in harmony.
Whilst there are a myriad of fit systems out there, remember, it is the skill of the fitter and your involvement in the process that will determine the quality of the fit – feedback, questioning and engaging in the process is key!
We see fitting as two sides of the same coin…
1. Maximizing Comfort and Injury Prevention
Think of the time spent on your saddle, gripping your bars, repetitively pedaling for hours and hours, day in, day out.
If any part of the bike doesn’t match your body’s natural posture or movement, you’re likely to experience discomfort and whilst cycling is a low-impact sport it is highly repetitive and improper bike positioning can lead to a variety of overuse injuries. A poorly fitted bike often causes repetitive stress on muscles and joints, leading to problems in the knees, hips, lower back, and even wrists. It’s not uncommon for cyclists to develop conditions like tendonitis or knee pain because of a misaligned saddle or poor cleat positioning on their pedals
One of the primary goals of bike fitting is comfort and injury prevention. Without proper adjustment, riding a bike can cause aches and discomfort in the short term and (worse case), injury and chronic pain in the long term. Preventing these issues and/or ensuring your fit isn’t contributing to an existing injury going forward is a big part of what we do.
Some relationships between fit and comfort:
+ Saddle Height: If your saddle is too high, you might overstretch your legs; too low, and your knees may feel cramped. A properly fitted saddle height ensures that your knees are slightly bent at the bottom of each pedal stroke, minimizing strain.
+ Handlebar Reach: The distance between your saddle and handlebars should allow for a relaxed posture. A poor fit can force you to overextend or compress your body, leading to tension in your shoulders, neck, and lower back.
+ Saddle Positioning: Besides height, the forward or backward tilt of your saddle influences your pelvis and spinal alignment, crucial for long-term comfort on longer rides.
2.1 Enhancing Performance: Ride Further and Faster
Bike fitting doesn’t just enhance comfort—it can also improve your performance on the bike.
Cyclists, especially those competing in races, know that even the slightest mechanical efficiency gains can make a significant difference in their riding.
Bike fitting optimizes your body’s interaction with the machine, ensuring that every pedal stroke transfers the maximum amount of power to the bike – minimising mechanical and aerodynamic losses in the process. When it comes to performance your goal should always be maximum output (speed) for minimum input (kcal consumed) – no awards are handed out for maximum power output in a race (not yet anyway)!
Several aspects of performance benefit from proper bike fitting:
+ Power Efficiency: When your body is in the right position, you expend less energy to go further. The right saddle height and positioning allow for a more effective transfer of force from your legs to the pedals.
+ Aerodynamics: For road cyclists or triathletes, aerodynamics is crucial. A bike fit can help you achieve an aerodynamic position without sacrificing comfort, allowing you to cut through the air more efficiently, which is especially beneficial for long rides or races.
+ Cadence and Pedaling Mechanics: A good fit allows for smoother, more efficient pedaling. It reduces excessive movement in the upper body and encourages a fluid circular pedal stroke, which reduces fatigue over time.
2.2. Developing Your Position
Professional cyclists didnt come out of the womb with a 12 degree TT back angle. Years of development, refinement and adaptation occurred to get them to where they are today.
If you are serious about extracting every ounce of performance from your body then we would recommend regular reviews of your position and equipment choices. Allowing a reasonable time to adapt and validate between these reviews ensures sustainable progress is made. We would usually recommend 6-9 monthly depending on the athlete and their goals.
3. It’s All About the Bike
It’s not, but it is. Something we also regularly see in store are geometry, sizing and/or set up mistakes that get copy pasted from one purchase to another.
“I’m a 56”, well what does that even mean? I ride a 58′ Tarmac and that fits great (yeah, but you’re running a 70mm stem and the post is inserted all the way into the frame).
When we fit with a view to speccing a bike, we are looking to recommend geometries and sizes that offer the most balanced setups, i.e.:
+ Room to Develop – your position isn’t shoehorned to the extremes of the bikes range of a adjustment leaving us somewhere to go if your fit requirements change over time
+ Optimal Compliance – enough flex in the post for comfort in the saddle, a balance of flex in the fork steerer relative to the riders goals and build
+ Handling – we don’t want your setup to disrupt how the bike was designed to handle
+ Aesthetic – you didn’t drop all those £££’s so that your bike looks like a dog’s dinner. We want you to be able to hold your head up high at the café stop with a bike that looks well balanced and athletic
Conclusion: Don’t Overlook Bike Fitting
In the quest for a better bike, faster times, or more comfortable rides, many cyclists focus on the tech and reviews and overlook the importance of proper bike fitting.
Yet, as we’ve seen, it plays a vital role in enhancing your comfort, improving your performance, preventing injuries, and safeguarding your long-term health. Whether you’re a beginner or an experienced rider, investing time and resources into a professional bike fit is a decision that will pay dividends every time you get on the bike.
