Precision Bike Fitting Service

A precision fitting provides vital information when purchasing a new bike, but can be equally important in improving the set-up of your existing machine. It is also the pinnacle of our day to day activity, keeping our customers’ needs close and our knowledge cutting edge as bike technology advances.

In our continuous survey to date, customer feedback told us 99.9% would recommend our bike fitting.

The Process

A Pearson Ultimate Bike Fitting appointment takes up to three hours. It is a very personal and considered appraisal of an individual’s cycling physiology, technique, and alignment.


Your technician will ask detailed questions about your riding history; how long, how far and at what level you have cycled in the past.

Establishing your targets and goals is important. It affects the extent to which your technician will, for example, prioritise performance over comfort. You will most likely use a different position for commuting than you will for a 100-mile sportive; just as your position for an Ironman triathlon will differ from that used in a Sprint event. Your position should be the one right for every occasion.


By studying your bike position, set-up and history, we can help identify the underlying causes of any cycling pain. This will also help reduce the likelihood of future injury. If you require physio or chiro for current symptoms, we are able to refer you to Summit Wellbeing, our in-house partners.

Bikes are generally symmetrical, just as the points of contact with the bike are fixed. Any asymmetry in the body will cause a rider to be unbalanced, as the body adapts to the bike’s symmetrical nature. This, in turn, can lead to reduced power output or discomfort. A Pearson precision bike fitting will take account of this asymmetry and adjust the bike set-up accordingly.

Muscle recruitment

Using ‘spin-scan’ analysis from our fitting jig chainset, we can build a picture of which muscles are utilised in different sectors of the pedal-stroke to improve efficiency.

Core condition

The strength of your core will affect your ability to maintain a good cycling posture. It also has implications for power transmission and the stability of the pelvis. A strong core will protect the lower back from pain and injury.

Range of motion

The extent of movement, particularly around the hip/pelvis area and in the hamstrings will affect the fluidity of the pedalling motion, as well as posture and ‘muscle-recruitment’ patterns. All of these can affect comfort and efficiency.

Cleat position

The most important ‘interface’ for power and comfort are a rider’s legs. The pelvis-saddle contact closes a ‘kinetic chain’ at one end, with the shoe-pedal contact closing the other. Your technician will devote a part of the session to aligning and balancing your foot/cleat position. An optional custom footbed may be recommended for greater comfort, stability and power transfer.

Anyone who plans to ride a bike for a period of time should have their position assessed. Regardless of experience or ability, all cyclists can improve their riding biomechanics by having a thorough analysis.

Most cyclists buy a bike without any assessment. Many riders have visited us subsequently with pain in their neck, back or knees. If you are considering purchasing a new bike and want to ensure it will fit perfectly, we recommend a bike fitting before you make your final choice.

We believe that fit is the pinnacle of our customer journey, from this point all else follows, from adjusting or renewing existing components and bike set up, to choice of new machine, to the way you ride your bike, it is the measure of you.

Our responsibility is to ensure that you will feel improvement following a one to one session, it’s all about you. 99.9% of our customers surveyed would recommend a fitting to a friend.

In an ideal world, this section wouldn’t exist. Unfortunately, the approach by many manufacturers to women’s bikes and frames is a misconceived ‘shrink and pink’ attitude; they simply offer men’s frames in smaller sizes and adjust the paint-job.

This approach is as patronising as it is inappropriate. For example, some manufacturers use steeper seat angles on their women’s frames. In fact, they should be doing the opposite. Generally, women have longer femurs than men, in relation to torso length. As a result, they need a shallower seat-angle to improve the connection between the bottom bracket and pedal axles.

A bike-fitting session with Pearson is the same, regardless of how many ribs you have. Thankfully, things are changing elsewhere, too. As more women take up cycling and triathlons, they are less inclined to compromise on comfort and performance.

Many of the latest women’s bikes and products, such as saddles and handlebars, offer genuine ergonomic advantages. At Pearson, we take time and care to select the most appropriate components for the individual rider. No shrink, no pink.

“Having had what I thought was the market leading retail bike fit previously, I can honestly say your fit was leagues ahead. It was a personalised fit and it was without a doubt the best £200 I have spent on anything related to my new passion for cycling.”


”I enjoyed the entire fit process. Riding home last night felt so good I was looking for every chance I could climb a hill again thank you.”


”As an inexperienced 60-year-old cyclist, this fit has been a great help to resolve all kinds of problems – the process was thoughtful and has made a real difference to my enjoyment.” 


“I found the fitting really interesting – it was good to understand some of the theory behind why you need to be in a certain position, and it was also useful to be given some other things to think about in terms of position and posture when riding to maximise efficiency and performance.”


“A bit late providing feedback – just completed Fred Whitton. All hip flexor niggles and back pain disappeared. Transformative! Best money I’ve spent in a long time👍”

Pete B

“Very knowledgable and finally felt confident ordering the right bike. Looking forward to receiving my data, I’m not sure I need it as I have ordered the bike. Many thanks!”


“I thought the whole thing was extremely impressive. My fitter was clearly very knowledgeable and inspired confidence in his suggestions. The rationale behind these was always clearly explained. I would never have made the changes to my bars, stem, or shoes without this and already it feels better on the bike. I’ll see how it is in the long term but at present I can safely say I would very happily recommend this to any cyclist who is riding reasonable distances on a regular basis, let alone those who want to ride seriously. Well worth it.”

Jim R

“Nas was brilliant, he did a full fit for my fiancé and a fit on the bike for me. Couldn’t be more happy with the results. First ride out on the bike afterward was dreamy. Finally managed to sort out the hand pain I usually get when riding so I’m thrilled! Now just need to get some miles under the belt. Thanks very much!”
