I picked up a book called "Zin and the art of mountain bike maintenace" this weekend at borders for $25. Its a great book written specifically for mountain bike repairs and maintenance. So far i am quite impressed. I am hoping to start doing all my own repairs and upgrades. I am going to buy a park stand and maybe take a 12 hour class in the off season. I always need to build and work on my own stuff, whether it be cars, computers, bikes, etc. Any thoughts???? Suggestions?
