Freewheel to Casette Conversion

Stumpmeister · #1 06-18.-2003

I have a 84 Stumpjumper that has fallen victim to the whirlwind of techno advancements in the past 20 years. Strong freewheels with the correct spacing and low gear ratios are not to be found. So, I have to convert to casette. I know, "buy a new bike you dinosaur!" But I want to keep this bike because I like blowing the doors off these 3000 dollar mail order sissies!. Do I have to get the rear stays spread? Can I do it myself or does it have to be done on a frame jig! The freewheel was a 5, Ultra 6 (primitivo!) Will I be able to do this? I am worried about sidestay clearance, chain type, chain rings, you hear what I'm saying? Help!
Thanks!
Chris
