Fulcrum Freehub Difficulties

[bthomas515]

I cannot find any info on this online so seeing if anyone here has some info.

Have some fulcrum zero wheels that I’m swapping to xdr freehub. Taking off the shimano one on the hub has presented a difficulty. I’ve taken off the bolt thing and the spacer thing. According to a YouTube video, the freehub should just slide off, that doesn’t seem to be happening.

Any info on how to get this freehub body off the hubs?

Free hub could be binding or bonded to the axel. Normally the free hub should just slide off the axel once you have removed the nut and spacer like you have already done.

Undo the non drive side end cap, remove the Black micro adjuster then you may then need to reinstall the end cap and tap the axel with a soft plastic mallet to remove the axel and free hub from the hub. You will then need to determine why the free hub is stuck/bonded to the axel, likely the free hub bearings bonded to the Al axel, normally the free hub should just slide off the axel once you have removed the nut and spacer like you have already done.

The axle is 'lobed'...just wiggle the FHB back and forth some while holding the axle stationary, and it'll come off.
