Park Tool  CWP-7 Universal Crank Puller for Square Taper and Splined Cranks

The universal design of the CWP-7C has a rotating tip pressed into each end of the tool (11.3mm and 16.3mm) so it will remove both square taper and splined (ISIS Drive, Octalink) crank arms. The CWP-7 is made for the 22 x 1mm threading in the common cranks.
