Universal Crank Arm Removal Tool

The Park Tool CWP-7 Compact Crank Puller is engineered to work with most 3-piece bicycle crank systems, supporting both square taper and splined crank arms for reliable removal.

Interchangeable Rotating Tips for Versatility

This tool features two rotating tips to accommodate different crank bolt sizes: a small swivel foot compatible with M8 x 1.0 threaded bolts (including square taper, SRAM® PowerSpline®, and BNI cranks for Bosch® e-bike systems), and a large swivel foot for M12 x 1.0 or M15 x 1.0 bolts (compatible with Shimano® Octalink®, ISIS Drive, and ISIS Overdrive systems).

Enhanced Leverage and Smooth Operation

Equipped with extra fine threads, the CWP-7 provides the leverage needed to remove even the tightest crank arms smoothly and securely. It requires an adjustable wrench for operation and includes a built-in 8mm hex for crank bolt removal.

Compatibility Note

The tool is designed for crank arms with M22 x 1.0 extractor threads and is not compatible with some fitness equipment using nonstandard extractor threads. Users should verify compatibility with their equipment manufacturer if unsure.
