Case Study: From Chronic Back Pain to Pain-Free Riding

TL;DR

Cycling-related back pain is often linked to a combination of position, movement, and load distribution rather than a single underlying cause. In this case study, a structured physio-led assessment identified the contributing factors and guided targeted adjustments to both the bike and the rider's movement. The result was a return to pain-free cycling, improved confidence, and consistent riding without the ongoing strain that had been limiting training.

Pain That Does Not Go Away Needs a Different Approach

Most cyclists experience some discomfort at some point. For most riders, it resolves with rest or a simple adjustment. For some, however, it becomes persistent — and the more typical responses (small saddle adjustments, time off the bike, following general advice from forums or coaches) provide only temporary relief before the issue returns.

When pain keeps coming back despite reasonable interventions, it usually means the underlying cause hasn't been fully identified. This case study shows how a structured assessment can provide that clarity, and what the practical solution looked like for one rider.

Meet Jane

Jane (re-named for the purpose of this case study) is a recreational cyclist in her early forties. She rides regularly, values consistency, and has built up to comfortable four-to-five hour weekend rides over the past few years. Over time, however, she began to experience lower back pain, as well as discomfort in the shoulders and neck, and pins and needles in the hands, during those rides.

Her Experience

The pattern was consistent. The pain appeared after longer rides, became more noticeable over time, and eventually started to affect her enjoyment of cycling. She tried the usual approaches — small saddle height adjustments, shifting her position on the bike, reducing ride duration — and each change provided temporary relief before the issue returned.

The Impact

The discomfort affected more than her rides themselves. It reduced her confidence on the bike, created ongoing uncertainty about whether her setup was right, and produced the kind of frustration that comes from repeated trial and error without clear progress. Jane wanted a long-term solution rather than another temporary fix.

The Assessment

The first step was understanding the full picture rather than focusing on any single variable.

Initial Discussion

We started with a detailed conversation about her riding history, when the pain appeared (specifically how far into a ride, where it was localised to, and whether it resolved between sessions), and how she had already tried to address it. This early stage often surfaces patterns the rider hasn't consciously noticed — recurring symptoms tied to specific ride types, positions, or training blocks.

Movement Assessment

Off the bike, we assessed Jane's lumbar and thoracic mobility, hip range of motion, and core stability. The assessment identified that Jane was quite stiff into thoracic extension, and felt tightness through her lower back on lumbar flexion. 

On-Bike Analysis

Jane then rode her bike on a trainer while we observed her position under load, and obtained video through motion-capture analysis. The findings aligned with the off-bike assessment. Where Jane was contacting the saddle was relatively “nose-up” causing her to posteriorly tilt at the pelvis. The result of this was a flexed / rounded lumbar and thoracic spine causing her reach excessively to the handlebars, and requiring her to extend at the neck to look up the road. As it turned out, Jane had moved her saddle forwards to lessen this reach to the bars, which had then resulted in her weight being too heavy on the front of the bike – a very likely cause for her shoulder/neck discomfort, and pins and needles in the hands. 

Identifying the Root Cause

The issue wasn't a single adjustment that needed correcting. It was a combination of bike setup (saddle position) underlying movement limitations (lumbar mobility) and compensatory changes (neck extension) that needed to be addressed. 

The Solution

The goal was to reduce the sustained loading on Jane's lower back, while improving her pelvic interaction with the saddle, and offloading weight on her hands. 

Refining Saddle Position

Saddle adjustments included small changes to height and refinements to the fore-aft position. The combined effect was to improve Jane's balance over the bike, allow her pelvis to interact more appropriately with the saddle – allowing a neutral, lengthened spine, and reducing the amount of neck extension that was required to see up the road. 

Supporting Stability

Alongside the bike adjustments, we provided guidance on some techniques to retrain anterior (forwards) pelvic tilt, and exercises to help loosen her stiff thoracic spine. 

The aim wasn't a general strength program, but rather to begin building the foundation that would support her new position on the bike.

Gradual Adaptation

Jane settled into these changes quite well, and at the one-month follow up stage, we ended up needing to lengthen her stem by 10mm due to the additional reach she’d achieved from a more neutral and lengthened spine. 

Reduced Pain

Jane reported a significant reduction in back discomfort within the first few weeks, and the ability to ride for longer than before without the pain that had been limiting her.

Improved Confidence

With a more stable position and a clearer understanding of why her previous setup had been causing the problem, Jane felt more in control on the bike, less focused on managing discomfort, and able to enjoy her rides again rather than tolerate them.

Consistent Riding

She returned to regular training, gradually extended her rides back to their previous duration, and built the kind of consistency that had been disrupted while the pain was unresolved.

Jane's Words

"I had almost accepted that back pain was just part of cycling for me. After the fit, everything felt more natural. I can ride without constantly thinking about discomfort, and that has made a huge difference."

What This Case Study Shows

Jane's experience highlights a pattern that comes up repeatedly. Persistent cycling pain is rarely caused by a single factor — it usually involves a combination of position on the bike, underlying movement patterns, and how load is being distributed through the body during riding. Addressing all three tends to produce a clearer and more lasting solution than addressing any one of them in isolation.

A Practical Self-Check

Consider this: does your discomfort keep returning even after you've made multiple adjustments to try to address it?

If so, the underlying cause may not yet have been fully identified — and another adjustment in the same direction may not be the answer.

The Aim

The aim is not to manage discomfort temporarily. It is to understand the cause, adjust the position and the underlying movement accordingly, and support pain-free cycling over the long term rather than in short periods between flare-ups.

This is the approach taken at Aerro Physio Bike Fit, where each rider is assessed individually and guided toward a sustainable solution rather than a temporary one. We prioritise a rider-centred approach that helps cyclists learn about, and address, their limitations on the bike to achieve lasting results. 

FAQs

1. Can bike fit help with back pain? 

Yes — particularly when the back pain is cycling-related and the bike fit is integrated with a movement assessment that identifies the underlying contributors. A structured physio-led approach can identify and address the position and movement factors that are usually behind back pain in cyclists.

2. Why didn't small adjustments fix the issue? 

Because the problem often involves multiple interacting factors — position, mobility, and rider history — and addressing only one of them rarely resolves the whole picture. Small adjustments in isolation can provide temporary relief while leaving the underlying cause unchanged.

3. How long does it take to see results? 

Many riders notice improvements within the first few weeks as their body begins adapting to the changes. Full integration of the new position and resolution of long-standing compensations typically takes longer — often a few months — but meaningful improvement is usually felt well before then. 

4. Do I need exercises as well as a bike fit? 

If they are indicated, yes. If the assessment identifies underlying mobility or strength issues, addressing those off the bike supports the position changes on the bike — and a fit alone may not be enough to completely resolve the issue without addressing those factors.

5. Is back pain common in cycling? 

Yes. Lower back pain is one of the most common complaints among cyclists, particularly those riding longer distances or in lower, more aggressive positions. It is usually linked to position, mobility, and technique. 

6. Can I return to normal riding after a bike fit? 

Yes. The goal is to restore comfort, support consistent riding, and allow you to do the kind of cycling you want to do. If significant changes are made to your setup, it may be recommended to gradually build up your cycling load, or an iterative plan will be made to achieve your ideal position over a few months.
