Having just got my first nice bike, I've decided to take my old garage sale special (that's a lie, I got it out of someone's garbage pile) Murray Mountain Shadow and turn it into more road/cruising style bike. I'm thinking I'll definitely need a new chain and cassette, and maybe at least one chainring (bent tooth). Also I'll be getting new skinny tires, and maybe new wheels (broken spoke in the front), however I may just opt for the Frankenstein method and steal some from other spare bikes I have. This bike is meant to be an ultra cheap, fun bike for cross training, road and rails-to-trails...trails. So, any suggestions for cheap parts and/or anything I may have forgotten to consider?
