Front axle

[Deebo]

So I bought this atlas x-type bike because I liked the alloy wheels, only problem is the axle is a 3/8 that is too big to fit the fork on my Schwinn. Is there a way to convert the axle of the rim to a 5/16? Thanks.

Probably not - the axle cone's diameter/bearing radius is matched to the size of the cup in the hub itself, and the cups are bigger because the axle's diameter is larger. It would take some bike shop magic to find the right combination, assuming it even exists.

Find a 3/8 front axle with the flat sides or grind flats on the one you have.

That's exactly what I need! Where can i find this?

I personally think those flat sided axles are junk. The threads strip out too easily - I don't think they are hardened like the originals.

I would just file the dropouts on the fork a bit larger to fit.

file 2 flats in each side of your axle, testing as you go.
quick and easy

I just sold one, I'll see if I have another.

Ok please LMK.

In the mean time I'll try filing this axle. Not good at it.

put a wrench on the left lock nut and grip it along with a spoke or few to hold the axle in place while filing the right side.
or the opposite if left handed
