Obviously many people have upgraded their bikes a TON. I was wondering how many components on your bike came with the original bike?

I'm guilty of the upgrades as well , and the only original pieces attached my frame are the headset, brakes, and crankset. The brakes will probably be done soon because they're just not as powerful as a good set from a decent component group. (I've had Shimano 105 brakes that were much better).
