What Makes the CWP-7 a Universal Crank Puller?

The Park Tool CWP-7 is a compact crank puller designed to handle both square taper and splined crank systems, including Shimano Octalink and ISIS Drive, in a single tool. Its two-piece design lets you switch between crank standards without carrying multiple pullers, making it the right choice for mechanics who work on a variety of bikes. Built from hardened steel, the CWP-7 delivers reliable torque transfer and thread-safe crank removal in a tool that fits easily in a kit bag or apron pocket.

The compact form factor doesn't mean any compromise in capability. The CWP-7 gives you enough mechanical advantage to pull stubborn cranks that have been seated for years, and it works with a standard wrench or socket so you're never looking for a specialty driver to get the job done.
