Park Tool CWP-7 Compact Crank Puller
The universal design of the CWP-7 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.
High quality heavy duty tool. This could hold up to every day use. Worked excellent, effortless crank arm removal on a 12 year old bike!
