gonzy on "How often do you change/buy a new bike and why?"

used to be every 2 years then i realised that i needed t get rid of a few.
current frame is a 2009 model i bought last year...stuck the 2014 kit on it of the old bike and sold that frame on. that frame was also a 2009 model which i bought 18 months earlier.
prior to that the last frame i bought was in 2006
i've only ever bought 3 complete bikes...2 were in the 90's and one was 18 months ago.
its my 40th next year and the wife has said i can pull the trigger on a new bike...the current one will stay as a backup bike and will eventually be handed down to my son
