These principles are at the heart of everything I do, applying to riders of all abilities and needs.

Why choose CORE Bike Fit?

1) My studio uses state of the art equipment to help us make informed decisions about your personal bike fit. Utilising video analysis, a Purely Custom Fit Jig, pedal analysis, saddle pressure mapping and foot pressure mapping systems to fully understand your individual needs.

2) My family background is shoes. I would have been the 5th generation of master Shoe Repairers if I hadn’t fallen in love with bikes. There is no coincidence I focus on the interaction between your feet, shoes, cleats and pedals. To me this is the single most overlooked and misunderstood interaction with any bicycle #focusonyourfeet

3) As an independent fitter I am not tied to using any product or to sell things as traditional bike shop might. I don’t suggest anything I personally would not use myself and everything has been chosen by me based on my research and experience using it.

4) My personal approach is to treat you the rider as the most important element of the Bike Fit. Working with you to understand your own goals and issues I tailor your bike to fit you, not you fitting the bike.

5) Having struggled for years with tight shoulders and neck pain when riding, I know how it feels to not be comfortable on the bike. I used to just grit my teeth and bare it thinking it had to be this way. Fortunately now at CORE Bike Fit Devon I can help you remove discomfort from your cycling position.

6) I have been trained by THE BEST trainer in the UK. My approach is different to bike shops as I use a range of technology along with my experience and more importantly your feedback to prove what we have done has made a positive impact on how you feel as an individual. There are no averages and rules of thumb used at CORE Bike Fit. The technology we employ is used to help us understand what potential there is to unlock in your cycling.

The kit you wear when cycling (this must include lycra shorts and a close fitting base layer or summer road jersey)
Your current shoes (if you do not already have cycling shoes please wait until your bike fit, as we will assess your feet and guide you to the most suitable pair of cycling shoes).
Your bicycle you want to be fitted to

My bike fitting studio is based in Topsham near Exeter. Your professional Bike Fit is only a short drive from, Exmouth, Woodbury, Exeter, Paignton, Teignmouth, Torquay and Dartmoor.
Yes. We leave enough time at the end of the session to make minor adjustments to your bike, including saddle changes, stems and minor alterations to handlebars.
If your bike requires more work and parts that we do not stock and that need to be purchased I can book the bike in to have the work completed.
The main piece of equipment is a Purely Custom Bike Jig, This allows me to set your bikes geometry on the jig and make dynamic adjustments as you ride. It allows me to see your power output, cadence and fluidity along with being able to change crank length, saddle height, angle, handlebar reach and height. Added to this is our saddle pressure mapping system which helps understand pressure on the saddle and understand if changes we have made have worked. New for 2024 is our foot pressure analysis system. This we can add to your shoe to see what your foot is doing in your shoe as dou pedal. There is reason I say we #focusonyourfeet in your bike fit.
On top of all this we use video analysis software from four cameras so we can truly see the effects each area is having on your setup.
