Hi I'm Phil, and I'm 14 year old. I've been mountain biking for two years now. I want a new bike, and now that I have some cash saved up I'd like to build it myself from the frame up. I haven't done much to my current bike beyond changing the tubes and putting on a bash guard, so I don't know much about how to put the bike together. Are there any uncommon tools that I will need? What else should I know?
