We have always advised on the correct bike size but began bike fitting in 2008. In the beginning your bike was fitted to a turbo trainer and the fitter would set about visually assessing your riding position by manually taking the relevant measurements. In order to make changes to your position, you would often need to get off the bike, components had to be changed which took a large amount of time and was often difficult for the rider to remember what the bike felt like previously. Whilst achieved many successful fits and many bike shops still fit in this way, we felt that a better solution must exist.

Today things are very different. We now use the Trek Precision Fit custom jig. The jig allows for new levels of freedom when it comes to on the bike adjustment. Every aspect of the jig is fully adjustable in a split second and usually with you still sitting on the jig and easily able to feel the changes.

Slow motion cameras combined with Precision Fit software allow us to slow your pedal stroke right down and observe your riding style in greater detail than ever before. This gives the fitter a dynamic leg extension angle that shows in real time how you would be pedalling under load which is much more accurate than by eye.

The Precision Fit system is a fully comprehensive bike fit which starts from the ground up with a cleat adjustment and gradually works through the bike section by section. We also have a computer saddle pressure map data logger to clearly show what saddle you need to match your sit bones and position.

We believe everyone regardless of ability, age or condition will benefit massively from a full Precision fit. Whether you are an elite racer looking for those essential extra watts, trying to sort that ache in your lower back once and for all or just looking for peace of mind that your fit is correct you will be amazed by the benefit of a Precision fit.

Most people don’t realise how comfortable cycling can be and you are often just a good bike fit away from unleashing your potential.

The Process

Your Precision Fit technician will talk with you to learn your goals and needs as a cyclist.

Before you get on the bike, your fit technician will assess your range of motion and flexibility.

You and your technician will determine your proper shoe selection and cleat placement to build a sound foundation.

Your on-the-bike fit starts with an evaluation of your current position and a simple overview of the steps to follow.

Set-up starts with saddle selection, and continues via a series of incremental adjustments to create your ideal biomechanical alignment.

Here's where your fit takes its final form, with proper stem height and reach, and handlebar shape and width to optimise your posture and power.

You'll end your session with a detailed document that defines your fit, and a follow-up appointment to guarantee your satisfaction.
