Back in the day, there were regular gauge spokes, like 14G, and then 120 gauge, which are called 12 gauge now, and 105 gauge, which were in between the 14G and 120G. They were strong, but not as heavy as the 120s. It's laughable now, because the problem wasn't the strength of the spokes, but the rims were weak, single-wall thin steel. What could go wrong?You could have railroad spikes as spokes, but it wouldn't make a difference with a weak rim. As rim technology improved, the heavy spokes went away. Oh, but they looked cool.

Anyway, I never see 105 gauge wheels anymore, although I do have a set on my Cycle Pro beach cruiser.

Does anybody sell 105 gauge wheels? I'm building a bike.

I should know this, but what if you have, say, a 39t chainwheel in front with an 18t cog in the rear? Would the odd difference require you to use a half-link, or a half-link chain? 36t - 18t, direct 1:2 ratio, no problem there. But get into 41t - 20t, or what if both are odd numbers, like 39t - 19t? They say your chain will wear out quicker with an odd ratio, but not so bad with the half-link. I had a 41t Takagi on my Schwinn back in the day that quickly chewed itself up.
