Park Tool Compact Crank Puller CWP-7C

The CWP-7 is a universal tool for removing both square taper and splined crank arms from 3-piece bicycle crank systems. The swappable rotating tip smoothly and securely presses the crank arm away from the bottom bracket spindle. The extra fine threads provide the needed leverage to remove even the tightest cranks. The CWP-7 requires the use of an adjustable wrench.
