The Velomotion Retül Bike Fit Process


Rider History Form and Interview

The purpose of this is to get to know the rider better and find out their reason for having a bike fit and also what short and long term goals they have set themselves, so we can work with this in mind. We also want to understand how you currently rate your cycling comfort. Is there a main issue/concern or particular focus area, for example anterior knee pain or lower back pain?


Physical Assessment

We carry out a physical assessment prior to a bike fit, as the optimal cycling position is not the same for everyone.  The assessment tests a rider’s flexibility, stability, biomechanical problems, limitations and strengths/weaknesses.  Based on our findings we can then build a better picture of the rider.  We often find that the pre bike fit assessment findings will explain the asymmetries and the movement patterns the rider then adopts while pedalling.

Where appropriate, we will prescribe exercises that will help with your cycling.   This may be for a variety of reasons – to prevent or remedy a current injury or help aid performance.

Leveling the Bike

The bike is levelled in the trainer.  The importance of levelling the bike is to put the rider in a ‘neutral’ position.


Sensor Placement and Rider Warmup

Eight sensors are placed each side of the rider in specific locations.  These locations are critical to ensure the measurements taken are reliable, as our fit decisions are largely data driven.  This is a very important part of the process.

The rider warms up and their movement on the bike is observed at various power outputs and positions, for example measuring a rider on the hoods as well as the drops.

Initial Data Capture

Initial 3D data captures are taken on both the right and left sides to gain baseline measurements. These initial captures will give us a good idea of perhaps why the rider is reporting a current problem, for example struggling to sustain the aero position on their triathlon/TT bike.

Capture rider video and images. Both these captures are used along side the data to aid giving feedback to a rider.

The data obtained is examined with the rider.  At this point an explanation and reasoning of what positional adjustments are required will then be discussed.

Positional Adjustments

The positional adjustments to the bike are now made. We have a fully equipped tool chest and hold a stock of various saddles, stems, handlebars and cleats in the event that they need changing.

Cleat position – cleats replaced if excessively worn, cleat fore-aft and rotation set

Saddle position – saddle suitability assessed, saddle height, setback, angle and rotation set

Handlebar/Grip (Arm pad/extensions on a TT/Tri bike) – stem length/angle assessed, spacer arrangement, handlebar suitability assessed, handlebar rotation and grip angle/rotation set, handlebar re-taped if desired.

Provide advice regarding pedalling technique and posture on bike

We then repeat the data capture/positional adjustment process until the final position is set.


Save Data and Zinn the Bike

Final rider data captures and images are saved.

‘Zin’ bike – A digital scan of the bike is undertaken to document the final position of various key components on the bike.

Fit Report is Generated

The rider’s fit report is generated.  The report consists of a cover page that explains the process as well as the positional changes made, the final rider ranges, the bike file and initial & final images.   Definitions of the rider’s ranges and the bike file are also included.

Before the bike fit draws to a conclusion a number of matters are discussed –

  • Future recommendations based on the outcome of the bike fit.
  • What to expect on the first few rides.

You can see a PDF version of the report you will receive on the Retul Bike Fit Report page.

The Retül Muve

The only difference to the Velomotion Fit Process to our ‘Pre Purchase Bike Fit’ is that we will use our Retül Muve fit bike to allow us to put a number of bike brands/models ‘underneath’ you as opposed to a bike that you currently own. We’ll give you an unbiased opinion of what we believe suits you best based on your riding position, goals and budget.

On the fit bike we can change your saddle, stem, bars, pedals and crank length to find your ideal position and equipment for road, mountain or TT/triathlon positions.

This service will ensure that you purchase a new bike that you will get the most out of.

  • It can avoid the costly mistake of buying an ill fitting bike
  • It avoids further purchases, ie different stem length/handlebar type etc
  • When possible we will help facilitate your purchase
