All I did was add the rack, not standard with the bike, put on the kitty litter buckets and add a homemade cue sheet holder to the handlebars. Okay since I ride clipless I guess you could say I changed the pedals but I consider that standard bike equipment in these days.
Pedals don't count. My thing didn't come with pedals. I supplied my own and the shop put them on. A simply replacing a worn equipment doesn't count either. The OP is really referring to customizing things like drivetrains and such. I got rid of my seat post because I knew it sucked based on my experience with my previous LHT that was stolen. The teeth on the post wore down and the saddle would not stay level. The stem was too long, so that eventually got replaced, but not for a while. And saddle is usually a matter of preference.
