Z= 1mm/1 year.

  1. ” Dendrochronology or tree-ring dating, is the scientific method of dating based on the analysis of patterns of tree rings”

The coffee stop today heralded the new theory that we could age slightly older cyclists in the same manner :

(30+y)/ {x =z}F

Where ‘y’ is the riders age over 30

‘z’ is the elevation of the stem above the headset

‘x’ is the amount of excused back pain.

‘f’ is the determination not to ride a Sportief Geometry frameset.

 

The net conclusion was that the commonplace, carbon 5mm headset Spacer, is added every 5 years.  The market survey of 40 bikes at the coffee shop and every cyclist on the road since, has confirmed the theory.
