Is there a way I can work out the length of Spokes I need without using a calculator?

Use an online calculator? Or measure the old spokes if you're relacing a wheel

The rim I'm using doesn't seem to be on any calculators

What rim is it and have you tried the calculator on Wallerbmx?

You could measure the ERD yourself. Get 2 spokes of known lengths, thread them into nipples in opposing holes until the tip of the spokes are level with the inner wall of the rim, measure the distance between the spokes when they're pulled towards each other and add that to the the collective length of the spokes.

Most rims and hubs use exactly the same length spokes, I've reused old spokes from mismatched rims, and never had a problem, even if they are longer or shorter, they always work.

So u for I buy some medium length Spokes they should work then?
Im going to try and find a rim with the same ERD and use that in a spoke calculator

Don't do something so stupid, odds are you'll get the wrong size. What rim is it?

OK so I found a calculator where I could use my hub and the ERD instead of just selecting the rim so I have found the right size Spokes. And it's the alienation mischief

The tubeless(TCS) rims?

What hub are you using?

Yes the TCS rims I don't think I'll be bothering with tubeless though. And lacing to an n4fl I'm fairly easy on wheels though so I'm confident that it will be strong enough.

Just find a rim that has almost the same height as yours. It would suck to get the wrong spokes and have them not work. I'm just saying it's not really as exact as everyone thinks. When I built up my g sport simian, the spoke calculate said I needed the same spoke length as my old hub, even the the simian had noticably bigger flanges, like a lot bigger than my old hub. I thought it wouldn't work, but they ft just fine. I think 184 will work with pretty much anything.

It said I needed 192 but I believe that is. Because it's a flangeless hub

That should be 192mm spokes.

Flange spacing and flange height are tradeoffs against each other a lot of the time. The Simian's flanges look bigger than they are.

I'd never reuse spokes, I built a wheel with some old spokes when I was bored a few years ago. Granted, the hub dimensions and the hole pattern on the rim were a good bit different to the original wheel but on the first half cab, I snapped 34 spokes, landing to both wheels.
Spokes bend to the shape of whatever they're first built to. If they're forced to bend back, they become very, very brittle and snap with very low impact. If you have to use old spokes, try to make sure everything is as similar as possible between components but you should always try to use new spokes for a wheel build.
