So I guess I have some questions:
1. How many gears can I use with the 6200 series drivetrain? I know the specs say the max is 28T but I've read others going higher. If the 28T is true then my options are limited to 6-7 speeds correct?
2. Will I run into chain stay rubbing with a 10-speed freewheel (If possible) after taking my rear spacing from 126 to 130?
3. What freewheel should I use and what chain should I use.
4. Will my front chain rings work with the newer freewheel?
5. Should I go with freewheel or cassette?
Sorry, I'm a newb and this is all a bit confusing. I want the vintage bike with as many gears as possible with newer 700c wheels.
I have modern brakes and will install those and know how to modify the frame/fork to mount them.....
Thanks

Hi Shawn
1. You can probably use as many speeds as you want, up to a 28t sprocket. I.e. you can use a ten speed cassette that is 11-26, for example.
2. Dunno...
3. You will need a ten speed chain (chains get narrower with more speeds), and if you want 10 speed, you will need a 10 speed cassette (a cassette is pretty much a modern freewheel). You will need a rear wheel with a freehub if you would like more than 7(?) speeds, or a threaded hub for a 5,6 or 7 speed freewheel.
4. Should do, I have run 2x10 with all the same drivetrain from a 2x5 setup, except the cassette and chain. Some parts are quite versatile, while some might not be.
5. Depends on how many gears you want, and the type of wheel available.
hope that helps
