I know they don't make the air cartridges themselves anymore. The fork already has the cartridges but needs a rebuild. Were you referring to their not being any cartridges made anymore or that there are no rebuild kits available? The guy with the fork says you can still get the rebuild kits in his ad, but I couldn't find any online.
The Judy with the Englund is supposed to be about the best you can get for a fork of it's day, and lighter than a coil/oil set-up, so if I can find a rebuild kit I want to try it.
I guess I'll just have to look into the stock forks you guy suggested more and find the best balance of performance and weight. I can't stand to add too much simply due to the fact that this bike already feels like a boat anchor compared to my other bikes(vintage road bikes).
