Park Tool 1971 Clamp Adapter for D-Shaped Seatposts

Park Tool 1971 is an adapter for repair stand jaws that allows more secure clamping of D-profile seatposts. It converts one jaw into a flat surface, providing better contact with non-standard seatpost shapes such as D-shapes. The adapter fits over the existing rubber jaw inserts and can be easily mounted or removed by hand — without tools.
