Saddle sores are one of the most frustrating problems cyclists experience.
The natural reaction is to blame the saddle.
So riders often start searching for:
- A different saddle.
- Saddle pressure mapping.
- Better cycling shorts.
- More expensive bibs.
- Stronger chamois cream.
Sometimes those things help.
But very often, they’re treating the symptom rather than the cause.
At Kernow Physio, we regularly see cyclists who have already changed saddles—sometimes more than once—only to find the problem keeps coming back.
The reason?
In many cases, the saddle isn’t actually the problem.
The Saddle Is Simply Where the Problem Appears
Think about it this way.
If your saddle is supporting your body correctly, pressure should be shared evenly across the areas designed to take your weight—primarily the sit bones.
When something changes in the way your body moves, that pressure changes too.
You may start sitting heavily on one side.
You may rock your pelvis with every pedal stroke.
You may slide forwards.
You may constantly shift around trying to find a comfortable position.
The saddle hasn’t changed.
Your interaction with it has.
What Causes Saddle Sores?
Saddle sores are usually the result of excessive pressure combined with repeated friction.
But why that pressure develops is the important question.
Possible contributing factors include:
- Poor pelvic stability.
- Limited hip mobility.
- A saddle that’s too high or too low.
- Incorrect saddle setback.
- Cleat position.
- Leg length differences.
- Previous injuries.
- Core weakness.
- Restricted movement through the spine or hips.
- Excessive movement while pedalling.
Simply replacing the saddle doesn’t address any of these issues.
Isn’t Saddle Pressure Mapping Supposed to Show the Problem?
Saddle pressure mapping is an excellent tool.
Scott uses it regularly.
But it should never be viewed as the solution on its own.
Pressure mapping shows where pressure is occurring.
It doesn’t automatically explain why.
That’s a crucial distinction.
It’s similar to taking a photograph.
The picture tells you what’s happening.
It doesn’t tell you what’s causing it.
Without a proper physiotherapy assessment and bike fit, it’s easy to misinterpret what the pressure map is showing.
A Real Example
A rider recently visited Kernow Physio with persistent saddle discomfort despite already having another bike fit.
Saddle pressure mapping showed that she was consistently loading one side of the saddle and struggling to remain stable.
Many people would immediately blame the saddle.
Instead, Scott looked beyond the pressure map.
A physiotherapy assessment revealed significant restriction in the rider’s left hip.
The hip couldn’t move efficiently through the pedal stroke, causing the pelvis to shift and altering pressure across the saddle.
The solution wasn’t a different saddle.
Instead, Scott:
- Made small positional adjustments on the bike.
- Opened the hip angle.
- Prescribed specific exercises to improve mobility and control.
As the rider’s movement improved over the following weeks, her saddle pressure became more balanced and the discomfort resolved.
That’s why saddle pressure mapping should always be interpreted alongside a detailed bike fit and physiotherapy assessment.
Your Body Shapes the Pressure Map
Many riders assume that pressure mapping measures the saddle.
It doesn’t.
It measures how you interact with the saddle.
If your hips don’t move well…
If your pelvis rocks…
If one leg functions differently…
If you’re compensating for an old injury…
…the pressure map will reflect those issues.
The saddle is often responding to your body – not causing the problem.
The Importance of Looking Beyond the Contact Point
Cyclists naturally focus on where they feel discomfort.
But experienced bike fitting often involves looking somewhere completely different.
For example:
Pain here…
…may actually originate here.
Saddle sores may be influenced by:
- Hip mobility.
- Core stability.
- Foot position.
- Saddle height.
- Handlebar reach.
- Previous injuries.
- Pelvic control.
Everything is connected.
That’s why a physiotherapy-led bike fit looks at the whole rider rather than just the contact points.
Why Cyclists Travel for a Physiotherapy Bike Fit
Many riders arrive at Kernow Physio after trying multiple saddles, different shorts and previous bike fits.
One reviewer wrote:
“The whole session was incredibly detailed… Scott carried out a full body assessment, identified areas of tightness and imbalance and explained how these could affect my position and performance on the bike.”
Another explained:
“He looked at how my body actually moves and made all the right adjustments. The difference on the road is amazing—no more back issues or soreness.”
Those comments highlight the difference.
The assessment isn’t just about the bike.
It’s about understanding the rider.
The Best Bike Fits Treat Causes, Not Symptoms
Saddle pressure mapping is an outstanding piece of technology.
But it’s exactly that.
A tool.
Like video analysis or motion capture, it provides valuable information—but only when interpreted by someone who understands biomechanics, anatomy and cycling.
That’s why at Kernow Physio, saddle pressure mapping is never used in isolation.
It’s combined with a comprehensive physiotherapy assessment, movement analysis and detailed bike fitting process.
Only then can the real cause of the problem be identified.
Stop Chasing Saddles
If you’ve bought multiple saddles and you’re still developing saddle sores, it may be time to stop asking:
“Which saddle do I need?”
And start asking:
“Why am I loading this saddle the way I am?”
Because in many cases, the answer isn’t sitting underneath you.
It’s coming from the way your body moves.
And once that’s understood, the right adjustments can often solve the problem without changing the saddle at all.
