There are obviously some great companies out there that do an outstanding job on suspension revalving. . . for a cool $150-$170 duckets. Has anyone experimented around with different fork shims themselves? I know my bike inside and out so I am confident in my abilities to work on the forks, but I don't have a clue where to start with changing out shims. Anyone have any experience in this area? I don't suppose there are any retired fork-revalving experts out there that want to give away all the secrets are there?!
