Replacement Spacer/Wave Spring/Retainer
Wave spring for Mountain Tamer Triple or Mountain Tamer Quad Plus  $2.50
Retainer for Mountain Tamer Triple or Mountain Tamer Quad Plus  $1.50
Note: the adapters come with a one retainer and one wave spring.


        The wave spring applies the proper force to always ensure a tight fit
        of  the chainrings allowing for tolerance variation.

        The retainer holds the chainrings securely and will not come off even             in the
most adverse conditions, yet can be easily removed with a                 small screwdriver or blade.
Included with the adapters
