Anyone know the thread size for the crank bolt on a Koxx1 hub
 

I have a standard white russian, with a Koxx1 hub and cranks. I mangled
the thread when removing the cranks last night, and need to get a tap to
chase the threads. Also need some replacement crank bolts,

Thanks for any help.

M12x1.0

Searching stuff like this tends to be pretty useful as this was just
answered a couple of days ago.

As long as you have the reinforced hub, above are the thread specs for
the crank bolts. The Koxx light hub will be M15x1.0.

Welcome to the forums.

So you're saying they use larger crankbolts than kh/nimbus hubs??? Are
you sure?

What? Are -you- sure you're reading things right? Maybe I wrote that
poorly.

Koxx (reinforced) ISIS, Nimbus ISIS, KH ISIS hubs all take M12x1.0
bolts. That is the standard size.

The Koxx "Light" hub takes bigger bolts M15x1.0. Since for the light
hub there is a larger diameter hole drilled out (for more weight loss)
it needs larger diameter bolts, hence the 15s.

Clear?

Hey, by the way- check the thread carefully on the tap. M12 x 1.25 is
very common, but M12 x 1.0 is not. I don't know why the 1.0 size was
chosen; it would have made it a lot easier if the bike industry had gone
with a more commonly available thread.

Good question; not sure what the answer is. I think they exist
though; a machinist friend of mine has a M10x1.0 tap which I assume was
part of a set at some point. If you find one definitely post about it.
If you've only messed up the outer 1 or 2 threads, you may be able to
fix it without needing a tap; might be worth taking it to a machine shop
for that though.
