I've recently started rebuilding my out-of-date M700. I got this bike back in 95 I think and it was the bomb back then. Now, it was all scratched up and the components were half busted. I stripped the bike, completely, I'm talking paint and all. It's naked and sexy right now in it's aluminum skin and now I'm looking to put some new technology on it.
I'm looking for some information on how to find components, headsets, forks...that fit it. Does anyone know of a manual I can get or where I can start looking before I just start taking the frame with me everywhere I go and trying parts on in the store?!

Don't throw away the parts you have, if you haven't already. They will help you find appropriate sizes of items like seatpost, headset, bottom bracket, derailleur clamps, etc. That or you can get a vernier caliper to measure things.

As far as one resource online? Not that I know of. You'll just have to do lots of research and ask lots of questions. And you'll encounter incompatibility issues along the way, so expect some frustration.

Also, you'll probably end up spending as much or more than you would on a new bike. However, if you love the frame, it's always an added benefit to be able to select the parts you want. If you are resourceful, you might end up with a bike that's better than a new one at the same price point.

For inspiration, search the net. Look for bikes you like and find out what components they have. Then give it a go.

thx for the help junkyard, those links are really helpful. i'll keep posting updates to the bike in case you're interested along the way. i found a certified frame painter so that's my next step. luckily, as you mentioned, i did save everything cause i figured there would be hangups.
i'd really like to salvage the old thumb shifters too because i like to feel the shifting, stupid as that may sound.
anyway, i'll keep posting and probably put some pics out too.
