Hi. I’m sorry if this has already been discussed (I’m kinda a newbie when it comes to this site), but I was wondering if I would be able to put Qaxle cranks on my KH 29 mountain unicylce. It is from 2008 if that matters. Thanks in advance.

The Q-axle cranks are a proprietary splined interface. I believe a 2008 KH will be ISIS, so you would have to swap out the hub. https://www.qu-ax.de/en/product/qu-ax-q-axle-disc-hub-red-36-holes/ You would be better off just grabbing ISIS cranks.
I’m not 100% sure if the older Onza KH hub would work with the Q-axle cranks, but I would bet money that they are a different spline.
Hi Joey,
as already said, the Qaxle are a no-go (no matter the year of your KH uni).
However, if you are looking for dual-hole cranks, you can buy KH Moment, KH Spirit and even Mad4One dual and triple-hole ISIS cranks (beware that the Mad4One are pretty but expensive).
If you are just interested by getting cranks from a different length for your KH29, any ISIS crank will work.
I had the same though than you when I saw the Qaxle for the first time. It will require a close inspection of both hubs/cranks to check. I just need to meet a rider with a Qaxle hub to compare to the KH/Onza cranks a friend of mine left home.
