Ok im trying to give as much info as possible so here goes…
I have a Qu-ax Trials (the one before the isis one) and
I’ve watched Evan’s crank de-nubbing tutorial and I know what to do and I have all the stuff but the problem is my crank bolt doesn’t allow it to happen. It looks like this…

And i’ve heard that you can replace the original bolt with this one…

so you can grind the nub off.
Will this work on my Cranks? Heres some ugly pictures lol…

I ground the nubs off the cranks on my 24" DX. The original bolts would not work for me either. I replaced them w/ those 2004 bolts and works fine now (now I actually preffer to ride w/ 170 mm Qu-Ax cranks and w/ the additional Q-factor, the nubs don’t bother me).

Make sure to put on a healthy amount of gear grease, so you can get the cranks off if you ever want to remove them again.

A crank puller no longer works for me. I have wedge a screw driver in there and rock it and the crank back and forth until I can pull off the crank. I’m sure doing this freequently will wear out the splines.

I bought the 2004 KH bolts for my DX, though I don’t think I have ever actually smashed my ankle on the nub, I did it just to be safe.

Now that it has a rounded bolt in there, it won’t hurt as much if the day does come.

Also, I don’t need a crank puller to remove my cranks… They’re pinch bolt cranks, you shouldn’t need a puller for them period.
