What is Bike Fitting?

The process through which we find the best way to set up your bike so that you can get the most out of your riding whether that be comfort, performance, effiency, injury prevention, or all of the above. It needs to be carefully personalised for each person to get the best outcome.

Bike Fit process

Rider History

​This allows for a broad understanding of the individual and has a great influence over every step that follows afterwards.

  • General Health

  • Medical

  • Previous Injuries

  • Occupation

  • Riding Level / Type


Screening Assessment

​This stage now places the emphasis on the current physical capacity of the rider and how robust they are for the level of riding.

  • Range of Motion

  • Flexibility

  • Strength

  • Muscle Balance


Rider Goals / Aims

​Next we need to align the rider’s current capacity with what they want to do or achieve. This is vital to be able to plan what aspects need to be addressed both on and off the bike.

  • Events

  • Races

  • Challenges

  • Riding Holidays

  • Commuting etc


Baseline Bike Measurements (Pre-Fit)

Using an X-Y self levelling laser, accurate measurements are taken of the bike’s current set up before any testing / changes are made.



Initial Dynamic Examination

Observations (both visually and with a camera) are made from all sides of the rider to look at current movement patterns, control, symmetry, pedalling technique.

The next part of this process is where rider feedback is critical - during this phase we will be looking to obtain information on comfort, pressure distribution, areas of strain, which muscles are tiring or working harder. The first part of this process is meaningless without the second part - this is what makes the fitting session collaborative, individualised, and interactive.


Adjustments

This process is meticulous and laborious as it involves making continual and incremental changes while closely monitoring responses in the rider’s body and also the rider’s own verbal responses (they can often be conflicting so its important to consider both aspects).

  • All contact points are considered from the shoe / cleat / pedal interface, the saddle, and the bars.

  • Crucially, changing one contact point will always have a knock on effect on other areas of the fitting.

  • Continual rider feedback on key areas of comfort, balance / stability, pressure distribution, efficiency, power
