It’s a question many cyclists never ask. We obsess over bike weight. We debate tyre pressures. We spend thousands upgrading wheels, drivetrains and suspension. Yet one of the biggest influences on comfort, performance and even injury prevention is something many riders overlook completely – how well the bike actually fits the person riding it.

The reality is that no bicycle comes perfectly fitted from the shop floor. Manufacturers design frames to fit a broad range of riders, but no two cyclists have identical body proportions, flexibility, mobility or riding goals. That means every bike, regardless of its price, can usually be improved. And often, the improvement is surprisingly significant.
SMALL CHANGES CAN MAKE A BIG DIFFERENCE
Most cyclists have experienced it. Your hands start going numb halfway through a ride. Your lower back tightens after three hours. Your knees ache on long climbs. You constantly shift around on the saddle trying to find a comfortable position.
Many riders simply accept these as part of cycling. They aren’t. More often than not, they’re signs that your position on the bike isn’t allowing your body to work efficiently. A professional bike fit aims to correct that by optimising the relationship between rider and bicycle.
Done properly, it isn’t simply about comfort. It’s about producing power more efficiently, improving bike handling, reducing fatigue and lowering the risk of overuse injuries.
WHY TECHNOLOGY MATTERS
Bike fitting has evolved enormously over the past decade. The days of adjusting saddle height with a tape measure and relying solely on experience are largely behind us. Today’s best fitments combine expert knowledge with sophisticated technology that measures exactly how your body moves while pedalling.
One of the most respected systems in the world is the Retül Bike Fit System.
Using advanced 3D motion-capture technology, Retül tracks the movement of your joints throughout the pedal stroke in real time. LED sensors placed on key anatomical points record thousands of measurements, providing an accurate picture of how your body moves dynamically – not just how it looks when stationary.
That data allows experienced bike fitters to fine-tune everything from saddle position and cleat alignment to handlebar reach and cockpit setup with remarkable precision.
NOT JUST FOR RACERS
Another common misconception is that professional bike fitting is reserved for elite athletes. In reality, recreational cyclists often have the most to gain.
Competitive riders might be looking for marginal performance gains, but weekend warriors usually want something even more valuable – to finish a four- or five-hour ride without unnecessary discomfort.
Mountain bikers benefit from improved control on technical terrain and better climbing efficiency. Road cyclists often discover a more aerodynamic yet sustainable position. Gravel riders appreciate the increased comfort needed for long days in the saddle, while eBike riders can reduce the fatigue that still comes with spending hours on the bike.
Simply put, every cyclist deserves to ride a bike that works with their body rather than against it.
GAUTENG’S HOME OF PROFESSIONAL BIKE FITTING
For more than a decade, Set-It-Up has specialised exclusively in helping cyclists unlock that potential.
Every fit is built around the Retül system, combining detailed physical assessment with dynamic 3D motion analysis to create an individually optimised riding position. Rather than relying on assumptions or generic sizing charts, every adjustment is guided by objective data and interpreted by experienced fitters.
Whether the goal is greater comfort, improved performance or resolving persistent discomfort, the process is tailored to the individual rider – not simply the bicycle.
To make professional bike fitting easily accessible, Set-It-Up operates from four locations across Gauteng:
- Lynnwood Cyclery – Pretoria
- Complete Cyclist Bryanston – Northern Johannesburg
- Complete Cyclist Rosebank – Johannesburg
- Complete Cyclist Bedfordview – Eastern Johannesburg
“As the owner of SET-IT-UP Custom Bike Fitting, my goal has always been simple: help every cyclist ride more comfortably, efficiently, and confidently. Since founding the business in 2014, I’ve had the privilege of working with thousands of riders, from first-time cyclists to elite athletes competing at the highest level,” said Marcel de Wit.
“Over the years, I’ve learned that a bike fit is about far more than adjusting a bicycle. It’s about understanding the individual rider, their goals, biomechanics, and how they interact with the bike. Every fit is unique, and I believe the smallest adjustments often make the biggest difference in comfort, performance, and injury prevention,” added De Wit.
“My role today extends beyond performing bike fits. I focus on maintaining the highest fitting standards across our studios, mentoring and developing our fitters, driving innovation within the business, and ensuring every client receives the same level of professional service, regardless of which location they visit.
“I’m incredibly proud of what our team has built. As we continue to grow, our commitment remains unchanged: to provide every cyclist with a world-class bike fitting experience that helps them enjoy every ride and perform at their best,” said De Wit.
THE UPGRADE YOU CAN’T SEE
Cyclists often talk about “free speed” – those gains that don’t require buying a lighter bike or stronger legs. A professional bike fit is perhaps the best example.
Unlike a new set of carbon wheels or a premium groupset, you can’t immediately see the difference. But you’ll almost certainly feel it. Every climb becomes a little more efficient. Every descent feels more balanced. Long rides become less about managing discomfort and more about enjoying the ride.
Before spending money on your next upgrade, it may be worth asking a different question. Not “What should I buy next?” But rather, “Am I really getting the most out of the bike I already own?”
