Bike fit reports

Whether you are going for a traditional or Retül bike fit you will be provided with a report of a few key metrics.  But which are the most important?  While the fitter will adjust you to the most optimum position for your body and performance goals, you must also ensure you are provided with a number of ‘fit coordinates’ so that you can adjust any other bikes you may have and gain further understanding about the whole bike fitting procedure.

Retül fits will automatically provide you with a report with a number of different metrics:

But at a minimum you should be provided with just 4 or 5 numbers:

Saddle height

Simply the distance from the bottom bracket to the top of the saddle (halfway between the tip and the tail).  Certain saddles this is adjusted to the rideable flat section, such as ISM Adamo.

Saddle fore/aft

–       the nose of the saddle relative to the bottom bracket.  This is a plumb line measurement.  This number will vary between road and TT bikes and whether it has to be UCI legal.

Cockpit

–       This depends on whether it is a road or TT set up.  For road bikes the two measurements of interest are; saddle nose forward to the centre of the handlebar clamp, and nose forward to the hood trough.  This second measurement is an angular measure.  On a TT set up the first measurement is saddle nose to the back of the armrest, and nose forward to the shifter pivot.

Handlebar elevation

–       For road it’s the elevation of the top of the saddle down to the handlebar, the top of the bar.

These are the key fit coordinates.  There are many more, but they are minor in comparison to these key numbers.  As shown above, the Retül system automatically generates these numbers and provides you with the stack and reach data to guide your purchase of an appropriate new frame.   If you are looking to purchase a new bike/frame then the Retül Müve fit bike is a fully adjustable rig to find your optimum position, and then generate these numbers to guide your purchase decision making process, or adjust your existing bike accordingly if you can’t bring your own bike to the studio.
