Wheels! please break it down for me s2 s7 etc.
« on: April 20, 2012, 01:36:00 AM »
ok so I am fairly new to collecting schwinns (have 5 of them now) and I still dont understand the difference in wheels, I see some people say it has s-7 wheels, or s-2's. Can someone please explain to me the different type of wheels used for primarily Heavy weights and middle weights??

Thank you!

S7 wheels are a bit narrower than S2's.S7's also use a specific size tire(26x1-3/4 versus 26x1.75) and won't interchange with other 26" wheels,whereas S2's can use most 26" tires.the rimbead diameter is different on S7 rims.i believe it is 597mm.all middleweight schwinns from 55 up used the S7 wheels.i don't know exact dimensions of the different wheels,but someone here will fill in the blanks.

26" S-7 wheels have a Bead Seat Diameter (BSD) of 571mm.  The best tires for these are the Kenda 26 x 2 x 1 3/4" ones.  S-7 wheels came on Schwinn's Middleweights, which are usually considered to be pretty common in a relative sort of way.

26" S-2 wheels have a Bead Seat Diameter of 559mm, and as previously stated you can use pretty much any decimal (1.5, 1.75, 1.95, 2.125) size tires on these rims. The old S-2 wheels are the same size as modern cruiser and mountain bike wheels. The S-2 wheels came on Schwinn's Heavyweights, and as most Schwinn Heavyweights stopped production in 1955-56 (only the Wasp and Phantom and Cycle Truck continued on) the Heavyweights are older and considered rarer and more desirable.  And since some of Schwinn's more collectable HW models (Phanton, Panther) used chrome S-2 rims, these parts are always in demand.

And since it was thrown out there, a BSD of 597mm is the size of Schwinn's skinny 26" wheels, the S-5 and S-6.

And since we are talking about wheels I might as well try to help out and throw in my two cents.

Schwinn S-6 wheels are 27"  and were used on the road type bikes.   Continentals, Varsities etc.

Schwinn S-5 wheels are 26" and have a raised center section and were used on Racers, early collegiates etc.

Heres another kicker.  Schwinn S-6 rims also came in 26" size.    They came on later Collegiates.  And happen to be a pain the butt to find.   lol



so Schwinn Made S-2 (heavyweight) S-7  (middleweight)  S-5 (5 speed/tourist style lightweights)  S-6 (Road bikes)  26" S-6 (later collegiates)

And add to the mix......20 and 24 inch S2's and S7's     I'm not a Krate guy so I don't know what type of front 16" wheel is on them.

Heavyweight is a slang term for Balloon tire bikes.
Balloon, middleweight, lightweight describe the tire size not the weight of the bike.

And all these years I have had it backwards I guess.... I always thought a Balloon bike was slang for a heavy weight bike, be it 20, 24 or 26 inch frame..... Heavy weight frames are different dimensions than middleweight frames... To me, if i have a set of S2's on a middleweight frame it's still a middleweight.....Hmmmm now has me thinking.. What would a Sting Ray with an S2 rear and S7 front be called then ?

When I was a kid in the 40's and 50's, we distinguished only between balloon tired bikes and skinny tired bikes. When the Schwinn middleweights came along they were still considered ballooners to us, but "skinnier" ones. With the advent of mountain bikes, the term "fat tire" came along. So what does all of this mean? Darned if I know!

S4 tandem rim is the same as 650b rim usually called 26x1 1/2".  S7 rim is the same bead seat as a 650c wheel.
