76 Schwinn Suburban 10sp - I need wheel specs please.
rear wheel has a fivespeed cassette with a GT500 rear derailleur. I need to replace these wheels with some tougher and lighter wheels and I am not confident in what size wheels I need to order.
I appreciate your help

It was specified with 27 x 1 1/4 tires, so you need to look for 27 inch rims. Aluminum will be a great idea. You also need a 5 sp hub in the rear, 6 or more will not fit the frame

I appreciate the feedback.
Any idea on axle size, or more importantly, the spindle size that connects the hub? The drive train is gleamin clean and I dont want to start retrofitting if I can order a wheel set that will take the 5 speed hub that is on there.
Thanks again.

As much as I like the high-flange hubs that are on there, the rim that they are attached to is heavy and weak. Are there any wheel sets out there that will take the stock freewheel that is on there?
I'm just looking for a new wheel set with a threaded hub that will take that 5speed freewheel. Sun CR18's definitely will work, but I want to be comfortable knowing which size hub will be acceptable.
I'm asking because of schwinns uncanny ability to make parts that are 2mm off on whatever part you seem to need and never find......
Appreciate the help very much.

i was just going to ask this question also, on my 72 suburban my front wheel is a tiny bit bent, it tends to rub on the front brake making a squeak sound, its driving me crazy and i just wanted to order a new pair of wheels that would accept the 5 speed freewheel.

The least you should worry about is the freewheel. You can find good replacement (great sometimes, like a Regina) 5sp freewheels for under $10.

There are plenty of places where you can get decent spokes for less than $0.50 a piece. And CR-18's can be had for less than $30 a pop. Your LBS may be able to lace them up for you cheap too if you're not comfortable doing it yourself.
And this will also keep you from having to worry about weird Schwinn stuff (though hubs were standardized 100mm front, 120 rear with 5-speed cluster). The weird Schwinn stuff was tire sizing and seatposts/stems.

27" cr18's it is. Thanks, everyone, for your help. I'm going to try to swap the freewheel. If it doesn't work, I'm taking your advice on the Ultra6....

Why 27"? Sure the bike was made with 27" wheels but 700c gives you much greater options for Tire choices and will fit just as well.
Also a '76 Suburban should be 126mm rear spacing which means you can use a standard 5, 6 or 7 speed freewheel.
Ultra-6 Freewheels aren't cheap either...i was looking recently and New old Stock started at 60 bux...used you couldn't really do for under 30 unless you wanted one that looked like hell.
Honestly Your cheapest (and possibly least painful) route would be to order new 126mm spaced 27" or 700c front and rear wheels (either would work) from somewhere cheap like Niagara Cycle and get a new 7 speed freewheel for 15 bux and call it a new set of wheels....those cheap wheels from Niagara are as much per wheel as a CR-18 rim.

I noitced your comment about needing a tougher rim a couple of times. Those old steel rims were really tough, tougher than the aluminum replacements IMHO. It's just that they weighed a ton. So don't make the change to get something tougher. You will be disappointed.
One term I would not use in describing the old Schwinns is weak. Most were way overbuilt, heavy as heck, tanks.
Your two cheapest routes: the new Niagara wheels as mentioned above, or cheaper yet, a good donor bike where you can "borrow" the wheelset. If you don't mind steel rims, you should be able to get a steel wheelset super cheap. Just post a WTB ad here or on your local Craigs List. Many people just toss the old steel wheels.
+1 Don't worry about reusing that cheap and heavy freewheel. Replacements are much nicer, lighter, and cheap.
I had a 1974 Suburban, it had 120mm spacing. I would still use a 126 wheel instead. Its a steel frame and it will fit. That will also allow you to go up to six or seven speeds cheap.
