1988 Schwinn Premis

I'm new to this forum, and new to cycling, well...road bikes anyway...I've just picked up a 1988 Schwinn Premis that sat in a house fo 20 years. I'm drawn to classic chromoly american made Schwinns...Obviously i replaced the tires but im wondering does it need an overhaul? I'm toying with the thought of learning how to do it myself.

We don't know because we don't have the bicycle in question, nor do we know anything about it.

I would:
  • replace the wheel bearings & new grease
  • replace the headset bearings & new grease
  • replace the BB with a cartridge BB
  • replace the chain with a KMC X8.93
  • closely inspect the freewheel/cassette, replace if needed
  • careful inspect the chainrings, replace if needed
  • check the rims for brake track wear - replace if worn - all new double butted spokes
  • check the wheels for spoke tension and true
  • replace all the cables and housings
  • replace brake pads
  • replace handle bar tape

Are you trying to keep everything stock, or upgrade?

I'm open to upgrading. If I can keep some stock items on it that would be great but I plan on riding this bike often. I'm a newbie to this whole thing (forgive my naiveté) but im pretty damn skilled with a set of tools so...

I *think* there's a pretty good chance an '88 Premis would've been made in Japan. At that time, some Schwinn models were being built in Greenville, MS and others were being imported. Regardless, it's a pretty nice frame.

And after nearly 30 years, yes, it needs an overhaul. Fresh grease in the bottom bracket, hubs, and headset at the least. Fresh brake pads are a good idea, too.

Like others have suggested, you should re-grease the bearings. If it were me, I'd remove the chain and clean it and clean the rest if the bike, some Tri-flo on the derailleurs, brake calipers. Oh, and make sure you can move the seat post, then lightly grease it. Just make sure everything is smooth and take it out for a spin.

I say this because you said it was stored in a house. If someone keeps a bike in a house for 20 years, there is a chance it wasn't abused or left out in the rain at some point in its life. Plus, it's just a bike. Kids ride them all over creation without a complete disassembly and inspection. As long as everything is lubed and tight, I don't see a problem. You'll know what needs attention pretty quick.

Do you have the proper tools to attempt this yourself? Thankfully there are a lot of how tos on how to accomplish maintenance.

As said, full overhaul and tune is likely in order. 20+ year old grease is likely hard and crusty. Will need to be replaced and bearings inspected and/or replaced at a minimum. Cables likely, and housings as well for best performance.

The Schwinn premis is a good bike! I have a few late 80's Schwinns and they are good rides. Keep us posted and upload a pic or 2!

I'll confirm the advice to clean and regrease ALL of the bearings before riding it one block. After 30 years you can be certain the factory grease has completely dried out and is useless. I've seen bikes with less than 10 years of non-use with fully dried out grease and 30 years makes that a certainty.

Oil all of the derailleur and brake pivots and lube the chain. Most likely the brake blocks should be replaced too. Does it have aluminum or steel rims? If steel, they are the first things you replace.

Otherwise don't "upgrade" until you have used the bike enough to discover what works and what, if anything, really needs to be replaced. "Upgradeitis" can be a real money pit unless done intelligently and for a reason.

By dried out, what do you mean? My 1990 Miranda Schwinn that I seldom used (less than 1K km) until last year was never regreased until last Summer. The only thing I ever did to it back then was oil the chain, axles and bottom bracket every other year or so with motor oil (didn't know better until last year). Still had its original chain that I replaced at 0.75 later last Summer.

When I opened up the wheels' axles, the bottom bracket and the freewheel, everything was still greased and turning effortless. The bearings as well as the bearing cages were still smooth. I still cleaned everything and regreased with marine grade grease since I was going to use it daily, rain or shine.

Wow thanks everyone!
I did my homework before buying the bike and 99.9% of what I read says the frame was built in Greenville, although, I wouldn't turn my nose up at a Japanese built frame, either. Regardless, I live in Chicago, Schwinn was a Chicago company for ages, and I'm always drawn to classic, American made stuff.
As far as overhauling and having the proper tools...I have the basics and I'm in the process of getting the specialty tools needed to do the job right. My local shop gave it a look and said it should be good to ride and I ride it almost daily. Also, there's another bike shop in town that actually opens up their shop to let people work on their own bikes.
Thanks again for the helpful replies.

They must have used better grease or the bearings were better sealed against evaporation than the ones I've seen with that much neglect. You've been lucky, I wouldn't recommend the OP assume he will be too.

Schwinn serial numbers are pretty well documented, whether the frame was built by Schwinn itself or contracted out. If you haven't done so already, you can probably cross-reference your bike's serial number to check who might've built it and where.

I totally get it. My Slingerland drum set was made in Chicago in the '50s.

Nice!
I'm going to take a wild guess here and say you're probably an Allman Brothers fan, too

Reasonable guess, but off the mark. Not that I dislike the Allman Brothers or anything, but Duane had already been gone a few years when I was born and I didn't even know he and I shared a nickname until a few years ago.
