This was removed from a brand new OEM 160mm travel E-Optimised Fox 36 air suspension fork. This is the new Glidecore air shaft and a great upgrade for older forks. Reason for sale was, I reduced the fork travel to 140mm with a new air shaft hence this was not required. It will come with a new snap ring and lower leg crush washers. Please note - this will only fit the reinforced E-Optimised forks, not the regular 36, 36sl etc.
