I'd guess it's the fork the one one pickenflick frameset comes with? Can't see many people changing the fork, assume it's the dirty disco but I'd call on one to check. It's available separately.
Ah I see, it's a 29"er Inbred the bag was hiding the decals! could be the other carbon on one fork they do? Could also be an eBay far east special,would be interesting to know!
