So, like many others, my headshok fatty ultra dlr 80 died and I am contemplating switching it out with a cannondale fatty rigid fork from a 29er. My fame is a 2006 cannondale f600 furio x.

I was wondering if this was possible. I understand the crown-axle measurement should be the same. Are there any other problems I may run into?

Both have the cannondale 1.5'' and are disc compatible
