If you can get hold of an old ODS unit ideally with a coil spring you'll have something halfway decent to keep you going.
...The Risse Genisis Air shock is a wonder. Good price, and LIGHT.Risse makes the only replacement shock for xlinks as well. I just bought one myself. Have have sent it back for a "softening". Came back and can't wait to mount it.Terry
