Park Tool CWP-7 Compact Universal Crank Puller
The CWP-7 is a versatile, compact crank puller designed to remove both square taper and splined crank arms from 3-piece bicycle crank systems with ease and precision. Featuring a swappable rotating tip, the CWP-7 smoothly and securely presses crank arms off the bottom bracket spindle, while its extra-fine threads provide the leverage needed to remove even the tightest cranks. Built from high-quality materials for long-lasting use, this tool is an essential addition to any rider’s or mechanic’s toolkit. Requires an adjustable wrench for operation.
