The Park Tool SPA-6 Adjustable Pin Spanner is purpose-built to fit pin holes on retaining rings found on self-extracting (or one-key release) cranksets, including models from Shimano, Campagnolo, SRAM, and FSA. The SPA-6 is designed for heavy-duty use and features adjustable width for compatibility with virtually all retaining rings.
