Spoke gauge on Schwinn Super Sport
Here is a puzzler. On Friday, I rescued an early 1970s Schwinn Super Sport as a new project. Digging into it today, I find that the rear wheel won't true up. Then found a broken spoke. Went looking on fleabay auctions for spokes and the sellers advertise replacements as .080 like my other road bikes. This Super Sport has the Weinmann Alloy Rims and the spoke thicknesses mic at .070 using dial calipers. (!) Front wheel is OK but spokes are also .070".
Leading question is: does anyone know what spokes are correct for this application? Should they be .080 with the alloy rims or .070"? It could be someone's re-lacing experiment, true, but the bike appeared to be wearing original or at least period Bell tires, 27x 1 1/4 : with the green tread marker visible, so I suspect the tires had little or no use. .
Deal for the bike was made locally through social media PM, when I went to retrieve it I never thought to check the spoke gauges, but then again this is my first Schwinn so maybe a learning curve is a given.
Appreciate any input. Cheers, nd2

you do not mention if spokes plain gauge or butted
you do not mention material
models below this such as Varsity, Continental, Suburban use Union galvanized 80 gauge
reasonable to think that since this model features a chromo frame and forged dropouts a lighter gauge may have been employed...

Are the spokes the same diameter at the ends as in the middle? Some spokes are butted, the last inch or so on either end will be thicker.

Upon further digging, you are correct. Double butted spokes, .080 at the ends and .070 in the mid-run. Galvanized. Approx. 11 5/8 inches long but I will have to remove the broken one to be sure.
This is exactly what I needed to know, from another SS owner. Thanks for that. nd2

if you look at the spoke heads you will see they exhibit the Union logo

Super Sports are fun projects, either to keep original or to modify. I've had a couple and the next evolutionary step, a '75 Sports Tourer. You should be fine with a straight gage .080 spoke as a replacement.
BTW, the tires, pedals, saddle, and bar-tape, are all replacements. Not a big deal, but this might guide you to lean towards modifications. We're here to help and look forward to seeing your progress.

Just to confirm that the tires were not original to the bike: Bell-branded tires, tubes, etc., did not appear on the market until the middle or late 1990s at the very earliest, long after that bike was manufactured.

They're probably 14-gauge (2.0mm) straight spokes with brass nipples, 305-310mm length. The wheels appear to be four-cross pattern, so the spokes have to be longer.
Just about any stainless spoke in that size should work for replacement purposes.

Right length, spoke gauge = nipple thread and Bob's your uncle.

Because you don’t want the ghost of Ignaz Schwinn to haunt you.

Stainless builds tension nicely, in silky, linear fashion - particularly when butted and / or forged. My experience and opinion, but I'm sure others who have built wheels have noticed the difference between stainless and zinc-coated mild steel wheel builds.
Also, at this point, it might be easier to acquire stainless at the bike shop.
