Crank pullers do one job: thread into the dust cap hole, then push against the spindle to pop the crankarm off. The problem is that "universal" crank pullers often aren't—different crank manufacturers use different thread pitches, and a puller that works on your Shimano cranks might not touch your buddy's Campagnolo setup. Park Tool's CWP-7 addresses this by including both common thread sizes in one compact tool, so you're not fumbling through a drawer looking for the right puller when you need to service your bottom bracket.

The CWP-7 handles 22mm x 1mm threads (the standard on most Shimano square taper, Octalink, and ISIS cranks) as well as 22mm x 1mm threads for other manufacturers. The reversible tip accommodates both splined and square taper spindle interfaces—one end flat for square taper, the other with a rotating pad that protects splined spindles from damage during extraction. Thread the appropriate side into your crankarm, snug it down, then turn the center bolt until the arm releases from the spindle.

What makes this version "compact" is the shortened handle length, which fits better in saddle bags and travel tool kits than full-size shop pullers. You sacrifice some leverage compared to Park's larger CCP-22 or CCP-44 models, but for occasional use or roadside emergencies, the trade-off makes sense. The 8mm hex fitting on the drive bolt means you can use a standard hex wrench or ratchet for additional leverage if needed.... Read More
