See it depends on the bike for me... Some are mostly original and some are far from. It's crazy!!
My winter beater is all original except for the front suspension, stem, handlebars, and left shifter/brake combo, pedals and tires of course. (1991 Haro)
My main commuter road is also mostly original. The rear rim, tires, pedals is all that has been changed, however front rim upgrade is coming soon. (2002 Schwinn)
My full suspension is.. ummmmm... Well it still has the original handlebars, shifters, brake levers. Everything else has been change ... some MANY MANY times (1996 Schwinn)
Those are the main rides....
