I recently picked up a 1982 Schwinn World Tourist at a garage sale that I am going to fix up and make into my first lugged steel bike. I didn't know until I started working on it that it has the Shimano FFS or Front Freewheel system on it. Sorry if this is a repeat, I did a search and didn't find much.

It seems pretty interesting and I can't decide yet if it is a pretty cool thing to have or if I should replace it with a new BB and crank system and an updated rear wheel cassette system.

Anybody else have one of these on their bikes? What do you think - do you like it or wish you had swapped it out? Are they easy to work on and overhaul?

All in all it is still pretty smooth but the bike doesn't look like it had much maintenance done in the last 30 years so if I can overhaul it easily I'd like to get it working as good as new.

I went on Sheldon's site and read all he had on it - a lot of information but still can't make up my mind or figure out how hard/easy these things are to maintain and work on.

Any thoughts and opinions and info are appreciated!
