For the bikes you have, you'll need bottom bracket tools and headset tools that fit your bikes, that most of these kits won't have, as they're made for newer bikes. A good approach would be to get a copy of "Glenns New Complete Bicycle Manual", which you can purchase a used copy dirt cheap on Amazon, or any other of the many good bicycle repair manuals available, or watch the Park Tool how to video's, RJ the bike Guy, for example, to get an understanding of exactly what tools you will need. Then purchase good quality tools, such as Park, Hozan, Pedro's, Sugino, etc. that you need, individually, rather than a kit.
