I came across an anomaly when replacing the axle nuts on my Onex29. On the older black rims the front axle nut I found out was a 3/8 ×26tpi, and the rear was an odd #9×26tpi however when I bought a 3/8×24 nut and used it on the back axle fine, but when I had the nut guaged at a bike shop, it fit a9×26 bolt. Does anyone know what the axle sizes are on the Onex29?

When you say #9...do you mean 9mm?
The only 9mm x 26tpi is an uncommon size used on campagnolo front hubs. That wouldn't be on your ONEX.
Metric rear axles are usually M10 x 1 mm pitch. A 3/8" - 24tpi nut wouldn't fit on it.
A 3/8" - 24tpi nut will kinda fit on a 9mm x 1mm bolt because the 9mm diameter is ~.020" smaller and the tpi is close-ish at 24tpi vs 25.4tpi if the nut is narrow enough (a wider nut will bind as 24 v 25.4 isn't close enough).
So, I assume you either have a 3/8" - 24 on the back of your ONEX -or- a weird 9mm x 1mm rear axle.
