Hey, I own a crappy Roadmaster mtn bike that i've been having fun with modding. The reason i'm riding a Roadmaster insted of a $2500+ bike is becase all my money goes in to my guitars and amps lol

With alittle over 100 miles on the bike now i'm getting tired of tuning that crappy rear derailleur, i'm going SS with it tommorow.

But what other fun mods should i do to the bike??? Suggestions please
