Is there a standard size inner tube that woks for the Hogarthian style harness?

I had an old tire inner tube I tried to use and it was way too big. With so many Mfg. Making kits, I would assume there is a standard size they are getting off the shelf. Any idea on what it might be?

Thanks,
 
I went to WalMart, jacked a ruler out of the school supply section. Then went to the bike section and measured tubes till I found one close to 2".
 
Stop by your local bike shop and ask them for some blown tubes. Sometimes they don't want to part with them (afraid you'll try to patch them) so explain what you want them for and let them cut the tube. As far as sizing goes, the best results seem to be 2.2" or 2-3/8" but the dead ones are usually free so collect a few different sizes and pick the one that works best for you.

Webbing's 2" wide ... seems like those would be too big.

I use 1.75" ...

They all stretch over time... get whats free, it'll work :p This isn't rocket science.
 
If they are a little too small you can cut across the tube diagonally to increase the size. One dead mnt. bike tube will last a lifetime.
 
what I want to know is precisely what size inner tube I need for AL80 and AL40 stages to capture the regulator hose.

I bought a wheelbarrow tube but it's too small and doesn't stretch much.


Thanks! :)
