I tried this fork, borrowed from a friend for a few weeks. I have a Velvet, he has a Slant. We both found the same thing, the fork is quite excellent on the trail but doesn't last we've had countless warranty issues. Somehow X-Fusion rushed their R&D or something and made a bunch of hideously unreliable extremely excellent performing forks.
If you ride everyday, it's 1 star. If you have a specific race rig, then these will match up well with your Schwalbe Nobby Nic 5 ride racing tires and Crank Bros pedals. If you only have the time to ride once a week you might be OK too.
5 stars of racing provided they survive the race. 3 stars for a once a week rider and 1 star for everyday riders.
