ok to set the fork story right. They (ARE) pitster forks, pitster pro bought the lower legs and springs from marzocchi, they were then inserted into the pister upper leg. they are pitster casings with marzocchi internals(along with the valving of pitster forks). end of story. so pitster forks sell for around $300 and zokes sell around $750. these are worth between $500-$600 to the right buyer!!
