I have a pretty cheap bike (about $100) i don't do real big tricks just manuals, wheelies, endos stuff like that. i was wondering what i could do to lighten it a little with out costing me major $$. also the bike has steel rims but i bet there probably junk compared to what u guys have. so what kind of rims should i look into that wont cost alot of money. do u think i should even replace them. i have only had my bike for a week but i am sure eventually the rims will crap out. (starting in spring i might go to the skate/bike park and i might go off some 3 foot ramps.
