It depends how you define &quot;casual&quot;. I tend to think of casual cyclists as avid cyclists who don&#x27;t race. Anybody who isn&#x27;t avid is just a guy&#x2F;gal on a bike.<p>By that definition, casual cyclists spend ridiculous amounts of money on cycling kit.  $2000 for a set of carbon fiber wheels. $1000 for a power meter. Trek has a custom line of bikes (Project One) that retail in the $7000-$15000 range (US).
