circa 2001/2002 Marzocchi Z2 atom 80 sports.
lighter chassis than other bombers of same era, alu steerer, drilled crown, thinner walled lowers, M-arch.
80mm of travel, rebound adjustment, coil and oil, polished silver with no decals, ~180mm steerer, disk and V-brake mounts
disk side seal will weep if storrd upside down but not really in normal use, could probably do with replacing in next few months but they are cheap and easy to do at home.
Great, super reliable fork that will keep going for years, perfect for older frame.
