110mm hub dilemma
In today’s lesson of the wacky and wild life of old bikes I am trying to figure out what to do about the wheels on my funky, old(!!!) Bianchi. 1speed, 110mm rear hub and the rear steel rim is about ready to crumble into a rust pile. Wheels are 650a, rim brakes and want to keep the 1 speed thing alive. The way I see it my options are;
- Hope I find used wheels in the same size. A 1-speed, 110mm, 650a rear wheel is a unicorn, yes? Well, except for the one I have...😬
- Spread the stays and keep an eye on out for something that would work.
- Build a set of wheels but they would look wildly out of place given the patina of the rest of the bike. (FWIW - I have a truing stand and I’m itching to build a set of wheels.)
Suggestions are greatly appreciated.

"If you build it, they will come."
Not sure who "they" is in this scenario, but when is coming ever bad?

in case it may be of interest/help 110mm is also the width of track rear frame openings and hubs

650a is a 590iso? Same as most 26x1 3/8. They're plentiful on ebay, look for a sun rim in plain silver and find a basic bmx hub or flip flop track hub. Spokes are easy and off you go. Just won't have an easy time finding good quality tires but basic mid-range tires are fairly easy to find.

Thanks for the help all. Any left field suggestions are always welcome.

If you want to find decent tires, go with 650b, just 3mm less radius than 650a.

Aye, tis true but then I may have an issue with brakes. The reach is already significant, around 75mm, so 3mm is playing with chance and Tektro 559s don’t fit the vibe I’m after but thanks for the suggestion.

Single-speed? Leave the 19th Century behind. Sturmey-Archer AW (and SRF3 alloy shell) hubs are natively 108mm OLD. (Wider OLDs are created by longer axles and spacers.)
High quality ISO590 (a.k.a. 26 x 1 3/8 a.k.a. EA3 a.k.a. 650A) tires are available from Schwalbe and Panaracer. Continental City Rides aren't listed on the company website but are available on ebay. Specialized (Roadsport) and Bontrager (T1) both list 590mm tires (although the kid behind the parts counter at your LBS will probably just look at you funny.)
Fun facts: Sturmey-Archer three-speed hubs made an appearance at the 1904 French Tourist Trials, were used setting Lands End to John o'Groats records beginning in 1907 and used in the 1913 Tour de France.

I'm a huge fan of IGHs but I'm going to keep this machine as free of cables as possible.
I took the plunge and bought a set of Sun Ringlé CR18 rims and now i'm scouting for hubs. Let's see where this takes me.

I'm making some assumptions - the front fork will take a 100mm hub, your frame/fork will take a solid 3/8" axle, and you bought 36 hole rims.
If so, here are some hubs that will work for you and look reasonably era-correct:
