Common Cycling Mistakes That Cause Pain: Bike Fit Myths Explained

Part 1 of a 3 part series on cycling myths and evidence based bike fitting.

Most cyclists do not question common advice.

They follow what they hear, what they see online, or what has been passed down over time.

The problem is that much of this advice is incomplete, outdated, or not individualized. Over time, these misconceptions can lead to discomfort, reduced performance, and persistent injuries.

In practice, many of the issues riders experience are not due to effort or fitness, but due to incorrect assumptions about how the body interacts with the bike.

Why cycling myths persist

Cycling is influenced by tradition, visual imitation, and simplified rules.

Many commonly accepted ideas come from:

• Observing professional riders without understanding context• Applying generalized formulas to highly individual systems• Prioritizing appearance of position over function

Research in cycling biomechanics consistently shows that rider specific variability plays a significant role in comfort and performance (Bini and Hume, 2015; Fonda and Sarabon, 2010).

What works for one rider may not work for another, even at the same height, flexibility, or experience level.

Myth 1: Lower is always more aerodynamic and faster

Lowering the front end is often associated with speed.

However, aerodynamic benefit is only one part of the equation. If a rider cannot sustain the position, overall performance declines.

Studies on cycling posture and efficiency show that excessive trunk flexion can impair breathing mechanics and reduce power output over time (Faria et al., 2005; Bini et al., 2011).

When a position is too aggressive, common compensations include:

• Increased upper body tension• Restricted diaphragmatic breathing

• Pelvic instability

• Reduced ability to maintain power

The most effective position balances aerodynamics with sustainable power production and control.

Myth 2: Knee over pedal spindle determines saddle position

The knee over pedal spindle guideline is widely used because it is simple.

However, it does not account for individual anatomy or movement patterns.

Research has shown that joint kinematics and muscle activation vary significantly between riders, even when positioned similarly relative to the pedal (Bini et al., 2014).

Using a fixed reference like KOPS ignores:

• Femur and tibia proportions

• Pelvic orientation

• Riding discipline and intensity

• Neuromuscular coordination

Saddle position should be determined by how the rider produces force and controls movement, not by a static alignment reference.

Myth 3: Pain is something you adapt to over time

Some discomfort during training is expected.

However, persistent or localized pain is not a normal adaptation.

Cycling related overuse injuries are strongly associated with improper load distribution and repetitive stress (Callaghan, 2005; Bini and Hume, 2015).

Common examples include:

• Anterior knee pain linked to saddle height and load imbalance

• Perineal discomfort related to pressure concentration

• Hand numbness associated with excessive upper body loading

Ignoring these signals often leads to compensation patterns rather than adaptation.

Addressing the mechanical cause is more effective than increasing tolerance.

Myth 4: A more expensive saddle will solve discomfort

Saddle comfort is not determined by cost or brand.

It is determined by how well the saddle matches the rider’s anatomy and position.

Pressure mapping studies demonstrate that saddle comfort is primarily influenced by pressure distribution rather than padding alone (Bressel et al., 2005; Gebiomized data).

Key variables include:

• Saddle width relative to sit bone spacing

• Pelvic rotation during riding

• Load distribution between left and right sides

• Interaction with handlebar position

Without addressing these factors, changing saddles alone rarely resolves discomfort.

Myth 5: Cleats should always be set straight

Cleat alignment is often standardized for simplicity.

However, natural foot progression angles vary between individuals.

Forcing a neutral cleat position can alter lower limb kinematics and increase joint stress (Sanderson and Amoroso, 2009).

Misalignment may lead to:

• Altered knee tracking• Increased rotational stress at the knee and hip

• Reduced stability through the foot

Cleat setup should reflect the rider’s natural movement pattern rather than an imposed straight alignment.

What this means for you as a cyclist

Most cycling issues are not random.

They are the result of how forces are distributed through the body over thousands of pedal strokes.

Final thoughts

Cycling myths persist because they are simple.

Human movement is not.

If any of these points feel familiar, there is usually an underlying reason.

In many cases, discomfort or inefficiency is not random but related to how the body is interacting with the bike over time.

A structured bike fit can help identify these factors and provide a clear, evidence based path forward.
