Bike Fit

A proper bike fit is one of the single most important factors for optimal performance and efficiency, injury prevention, and comfort on the bike. It provides the rider with the most economic means of expending energy, and it also help prevent pain that is common in the knee, hip, and lower back, particularly with riders who are trying to adapt their bodies to the bike they already have purchased. Cadence offers the Retül system which reads the rider’s movements while they are in motion on the bike and accounts for all three planes of movement (3D). This type of data cannot accurately be captured with 2D video, static fitting, or fitting by ‘eye’. We eliminate the guesswork and assumptive nature of bike fitting. The result is that the rider will have a true fit to his or her bike, maximizing efficiency and performance while avoiding discomfort or injury.

During your bike fit session, all data is captured on computer and the client is provided with a comprehensive report showing their measured cycle position. We also offer cleat adjustment ensuring your cycling shoes are properly aligned. The data provided in your bike fit session can be used to fit to any bike.

Your fitting will take 2 to 2.5 hours and cover the following:

Physiological check: Includes hamstring flexibility, check for leg length discrepancies and feet pronation all of which have a bearing on your comfort on the bike

Cleat fitting: Incorrect cleat fitting accounts for most knee issues we see so correctly aligned shoe cleats are critical to ensure comfort and maximize power into the pedals

Adjustment: When we get you on the bike we will start to look at optimum measurements for saddle height reach to the handlebars

3D Analysis: The Retul 3D analysis allows us to assess how your knees move during your pedaling action

Measurement: You will be provided with a report showing 17 different measurements for you bike fitting

What you need to bring along

For your fitting, please bring your bike, cycling shoes, tight cycle shorts and shirt. The fitting is done on your own bike in a static turbo trainer. You will pedal during the session but it will not be a stressful workout.

The price for the Bike Fit is £180.00
