Cone compatiability in old Formula (MTB) Hubs from 90s

Hi,

I've picked up an old mountain bike to be my winter commuter that I'd guess is from sometime in the 90s (grip shift, non-cartridge BB, quill stem, etc.). This bike has a set of 26 inch wheels with formula hubs - and I'm sure they aren't the best hubs because this is a pretty low-end bike. The cones aren't in the best shape (one is pretty bad). I'd like to replace them but wouldn't even know where to start finding cones for these hubs. Could I replace with any old cones for MTBs? I'm not sure how much difference there is between cones. Even if it isn't perfect, I'd imagine it still be better than the old cones in there. If I can, I'd prefer not to replace the wheels, which are otherwise fine. Any thoughts?

Thanks

Bring the old cones into LBS and see if they can match them, ive had good luck doing the same. I may be wrong but there is only so many different size bearings.

Check these. You will need to measure yours to see if they have them. http://wheelsmfg.com/tech/PDF/wheels_cone_chart.pdf

What you need to pay attention to are four factors: Threading and diameter, which are going to be fairly consistent for a given type of hub (front/rear, bolt-on or q/r) but can vary; and the diameter and the depth of the cylindrical portion of the cone. The diameter generally cannot be much larger than the original or it will bind against the dustcap or seal. If it's too small it will allow in contaminants, though you can avoid that with some ingenuity (o-rings, silicone seal, etc). The depth must be enough so that the adjustment flats on the cone are exposed. If the depth is larger than the original you will need to adjust with narrower spacers or locknuts.

Thanks for the info. I'll just take the cones into the LBS for a match.

Typically Formula, Joytech and Quando use the same grey cones for their basic front and rear hubs. Unfortunately, there isn't exactly a small parts market for the same. Wheels Manufacturing stuff is very generic - and like with my generics - it often helps to have a 1mm spacer or two lying around to ensure that flange center to locknut dimensions are preserved.

Hence, I will be ordering Joytech/Formula/Quando cones in my next order from Taiwan.
