These first year Trek 728 came with Suzue sealed bearing hubs from what I read on the Trek brochure. That's what is on this bike. I think is was the 1983 model with Helicomatic hub that everyone raves about. I'm glad I don't have to deal with that type of hub from the bad reviews I've read.
I will be swapping out the Huret f/r derailleurs for Campagnolo derailleurs I currently have but I'll keep the original parts incase I want to return it back to stock.
Nice Trek Bikemig. Is that also an '82 year model? Looks like the same center pull brakes as mine. I have the 24" version and is a good fit.
