I've ran a Felt Airfoil (pictar) on my Spicer for six months now. The fork came used with the bike, no idea how long the previous owner had it. I ride it on the street, on crushed limestone paths, at the velodrome, and anywhere else I go. No problems, its a decent fork by all accounts and gets the job done.

I'll mount my Rev-X's up and snap a photo for carbon overload one of these weekends
