Replacement Parts for Shimano 200gs
Hello, all!
After an unpleasant incident involving my commuter motorcycle and a stopped vehicle, I find myself back to walking, bus-riding, and, best of all, bicycling. To get around, I broke out my old Diamondback Sorrento, vintage 1991, and got to pedalling. My problem with this involves 20 years of poor to nonexistant maintenance, meaning that eventually I'm going to have to replace parts. So far, everything still working, mostly. The rear brakes squeal, the front derailer only works on two of the three gears, the rear derailer only skips 1 of 7, and the seat post is completely frozen in place. Technically, though, it gets me down the road.
Obviously, I could just buy a new bike. But, I've had this guy for 28 years and I'm kind of attached. Downside is, once I start replacing drivetrain bits, it looks like I'm going to have to replace everything. So, i guess my question is which Shimano set works best as a replacement for the old 200gs the bike came with? Purpose of the bike is urban riding, with roads, sidewalks, and dirt paths.

200gs was so opposite from high end , Id just look for a 2nd one , to replace it or cannibalize for parts
derailleur hanger alignment, with bike shop tool is always a good first step..
Id drop by a Bike Shop for spring service specials Now,, since you speak of several issues..
Or shop for a reconditioned, used, bike ..

That was somewhat lower end mountain bike stuff back when.
A Tourney RDER will be totally adequate, although an ALTUS may be a good choice.
"Higher" levels will be for more speeds and thus narrower cages etc. That can cause chain rub that you didn't have before.
FLUSH the shifters with WD-40. That often "fixes" them.
(especially when the front drops from high to lowest and totally passes the intended middle)
