Check the threads, are they stripped or messed up somehow? Any little
bits of metal sticking out?

I had to have the threads on the crank retapped once. It cost like
under $5 at a bikeshop.

Yeah the threads look a little mucked up but it doesn't look too
terrible. I took it to a bike shop but they said they didn't have the
right tap for it.

There is also a lot of anti-seize in there so if some of it looks grey,
that's why.

Ah okay, so with all of this being said. Do the Koxx and KH hubs take
the same size ISIS bolt? Also, if I take it into a bike shop to be
retapped, what size thread needs to be tapped?

If it is the same size as the KH you wont find the tap at the LBS, I had
to go to a Machining Shop that specialized in metric as it is a large
tap with a very fine thread, can't recall the size anymore I think it
was a 10mm and the finest threads. I called HI Nu Tek Inc in sarasota
fl and the guy cleaned the threads for me for free.

I learned not to remove ISIS cranks with my old non ISIS crank puller.

if they both go in the same distance of approx 2 threads, the threads
and look damaged and from what someone said that it's a funny fine
thread then id suggest the bolts are a different thread. If it was me
and i couldnt find the correct bolt then id be tempted to drill and tap
it to a slightly larger size that i had a bolt for. but that is me and
i have a decent workshop and no decent bike shops around!

I've seen several posts regarding stripped threads. Check out a thing
called a heli-coil. It's a bit of an investment, but it's a really easy
thing to master and you retain the same size threads. You drill out the
the old threads, tap it for the heli-coil, intstall the heli-coil, and
you have new threads that are as strong or stronger than the
originals.

It'll work as well on any part of a uni as it does on stripped spark
plugs threads, engine case threads or whatever. You can pick up sets at
any auto parts store for just about every thread size.

Before doing anything, find out the right bolt for your hub. Don't
drill, tap, force, or mangle anything before you at least know what is
supposed to go in there. Any well stocked machine shop will have all
the metric bolts, taps, and thread gauges to determine what belongs in
that hub if you can't find out from some other source. When you find
out what the right size bolts are, buy them and try them. If the
correct bolts don't work, then first chase the threads with the correct
tap. If the threads won't clean up decide where to go from there. Over
drilling your hub to put in a larger sized bolt or Helicoil will weaken
it.

Why do you think the KH bolts will fit the Koxx hub? If Koxx isn't Isis
why would would the bolts be the same size? Has anyone else
successfully fitted KH bolts into a Koxx hub? What happened to the
original Koxx bolts? Don't the Koxx and the Koxx light hub fit
different sized bolts, which hub do you have?

Lots of questions, but maybe you are trying to fit a square peg into a
round hole.

This is all stuff I'm trying to figure out but no one seems to have the
answers, I suppose I'll have to email Koxx. The hub is from before the
light hub came out so I assume that means its just the standard
reinforced hub.

Thanks for the advice Harper, I wasn't planning on doing anything until
I figured out what bolt it needs.

According to the Koxx website the 12mm bolts fit the standard hub and
the 15mm fit the Light hub so there is a really obvious difference in
size between the Koxx bolts.

Kris Holm bolts are also 12mm.

Would that then also mean that the threads are the same?

No. Extra fine metric threads are not as common as SAE fine threads but
they do exist. Sorry I don't know the pitch of either one of those
bolts. I hope you can find out without having to take it somewhere or
buy a thread gauge.

I just had Spencer verify that his KH bolt fits perfectly into his Koxx
hub. So unless over the years they've changed the thread (the one I
have is older than his) it should be able to fit the KH ISIS bolts
fine.

So it may not have been the greatest decision but I decided to just be a
man about it and force it in there. I was able to thread both cranks on
completely but when I took out the bolt there were some very fine
strips of metal in the threads which is never very comforting. Should I
be worried about that? Have I just carved myself a new path? Is that so
bad?

EDIT: It -was- the correct bolt size, I'm just not quite sure what was
going on in there.
