Cycling Demystified - The Art, Craft & People Behind Bike Fit

In this episode of Cycling Demystified, Way, Matt, and Chan reflect on their recent trip to Málaga, Spain, for a bike fitters' meetup organized by JCP 360 and Pedalling Perfection.
The team explores how external environmental factors, nervous system feedback, and wide-ranging fitting tools shape how a bike feels, emphasizing that a successful bike fit depends just as much on human connection and wider life context as it does on mechanical adjustments.
Key Takeaways
The Málaga Effect (Environment vs. Mechanics):
Riding on pristine Spanish tarmac under sunny, stress-free conditions makes almost any bike setup feel comfortable and fast.

Returning to harsh UK commutes highlights how environmental stress, road surfaces, tire pressure, and weather dramatically alter ride quality on the exact same setup.

Nervous System & Psychological Stress:
The state of the human riding the bike influences physical comfort. Life stressors—such as work tension, family demands, or riding in chaotic/dangerous environments—elevate central nervous system stress, which can manifest as physical pain or discomfort even on a millimetre-perfect mechanical setup.

Power output acts as a natural support mechanism: pushing higher watts drives force into the pedals and unloads the saddle and hands. When riding slowly or relaxing, more body weight transfers to the contact points, potentially causing discomfort.

Multisensory Feedback in Bike Fitting:
Communicating with clients requires diverse sensory entry points. For example, a fitter used the sound of the bike to help an audiologist client perceive smooth, efficient pedalling mechanics when standard visual cues or subjective feelings weren't clicking.

Fitters use various sensory tools—such as scent, visual data, or pressure mapping—to lower nervous system stress and rebuild body awareness.

Technology vs. Human Connection:
Objective tech tools (like pressure mapping or 3D data) are valuable for identifying imbalances and reconnecting riders with hidden body tension.

However, data cannot tell a rider how they actually feel. Fitters must avoid "complexity bias" (assuming more data equals a better fit) and focus on listening to the rider's subjective experience.

Diverse Toolboxes for Unique Riders:
There is no single "correct" method to complete a bike fit; different fitters utilize varied philosophies and toolkits.

A great bike fitter adapts their communication and methods to match how each individual client process information and interacts with their bike.

In this episode of Cycling Demystified, we dissect the mechanics, nuances, and real-world trade-offs of progressive road geometry—a design trend characterized by steeper seat tube angles and longer frame reach.
Moving past surface-level marketing, the team explores how positioning riders further forward impacts weight distribution, hip angles, component design, and overall sustainability.
Key Takeaways
The Reality of Progressive Geometry: While pitching the body forward opens hip angles and increases power delivery for aggressive aerodynamic positions, it fundamentally shifts how a rider manages their relationship with gravity.

The "Weight on Hands" Misconception: Overloading the upper body isn't solely caused by a forward saddle; it often stems from hip instability. When a rider's hip angle is too closed or their cranks are too long, the pelvis rocks, forcing the hands to brace against the handlebars to compensate.

The Ripple Effect on Bike Design: Progressive geometry relies on a system-wide shift in bike design. Increased bottom bracket (BB) drops (lowering the rider's centre of gravity) paired with shorter cranks (under 170 mm) allow for wider tire clearance, stable cornering, and smoother hip movement.

Re-evaluating "Endurance" vs. "Aggressive" Bikes: Endurance setups aren't inherently more comfortable for every rider. Cyclists with shorter torsos, long femurs, or specific hip flexion restrictions often require a steeper seat tube angle and shorter cranks to achieve a comfortable, pain-free position.

The "Watt" Reality Check: A forward, progressive position demands enough force through the pedals to lift load off the front end. Fitters must balance a rider's speed goals against their real-world riding habits, strength, and ride duration.

Is your ability to handle and pilot your bike being hampered by a poor bike position?
Or maybe you haven't had enough time or experience to adapt to the handling / confidence / neuromuscular demands of cycling yet?
In the third and final installment of our Pedaling Biomechanics series, we shift focus from the hardware and physical body capacity to the element of skill, training, and weight distribution.
We explore how handling confidence, cognitive stress, and weight placement dramatically influence real-world performance, proving that raw aerobic power is meaningless if you lack control over the bike.
We also discuss Progressive Geometry Trade-offs: Modern "progressive" geometries (steeper seat tube angles seen in TT, gravel, and mountain bikes) move the rider forward and up to open hip angles and improve climbing traction. However, this places greater demand on the upper body and alters gravity balance. Does this matter to you?
Finally we discuss the Remco Effect vs. World Tour Aerodynamics: Analyzing Remco Evenepoel’s TT World Championship victory, the team highlights how a balanced cockpit and higher base bar offer superior cornering control compared to ultra-low setups that ruin weight distribution and waste speed in technical sections.

In part two of our deep dive into what is effective pedalling mechanics, we shift our focus away from the bike & components and investigate the true engine: the rider’s body.

The real question behind this whole series is: How good do you really want your bike riding to feel?

If you're chasing component change after component change and solutions only through adjusting the bike, then you are missed 50% of the equation. Bike's won't ride themselves, so a rider's capabilities in strength, flexibility, co-ordination and movement experience will affect the overall outcome more than simply the bike itself.

We break down why off-bike assessments matter, dispelling myths around static flexibility tests in favour of evaluating how a cyclist moves dynamically and controls their own body in space.

We also want you to understand how to see yourself as a unique individual and not be satisfied with simply conforming to the average orthodoxy. At the end we give you 3 pillars of off-bike assessment so you can begin practicing yourself straightaway.

In this first part of our deep-dive exploring the biomechanics of pedalling we examine how the bike itself creates the environment in which our body has to operate.
This dictates the options we have to create good movement. We challenge conventional algorithmic bike fits that rely purely on knee angles, reframing saddle height, cleat position, and crank length around whole-body movement.
By examining how foot stability calms the nervous system and how modern crank lengths relieve hip flexion, we explain how you can unlock both comfort and efficiency.
Finally, we wrap up with an insightful discussion on posture, breathing, and why we should view cycling as a dynamic, whole-body gait rather than just legs moving like isolated pistons.
Is this the reason why Pogacar and Contador are / were the greatest cyclists of their time?

Key Areas of Exploration:

The Two Pillars of Pedaling: Generating forward force (watts) and maintaining stability.

The "Sit-to-Stand" Test: This illustrates how hip extension, foot placement, and balance work together to mimic optimal muscle recruitment during a pedal stroke.

Foot Stability & Proprioception: Bike fitting starts at the foot.

Saddle Height vs. Leg Extension: Unlike running, where the leg fully extends, cycling is constrained.

Optimizing Crank Length & Hip Angles: Shorter cranks are becoming essential—especially on modern, aggressive road and gravel geometry.

Fore/Aft Positioning & Body Function: Do you need to have a ripped upper body to ride a progressive forward position?
