My last bike was puchased in the mid 80's so I am a bit behind the times when it comes to all the new equipment. Looking to buy a new bike soon so I have allot of catching up to do. I want to be able work on the new bike like I did with my old so what is the best book out there? Zin, Bicycling Mag's book, Park Tool's book seem to be the top choices. Any others? Thanks very much.
