Overview
Why Do Pros Use the PW-4 Pedal Wrench?
The Park Tool PW-4 is a professional-grade pedal wrench built for the demands of high-volume shop work. Its 15.0mm offset head clears the crank arm cleanly and provides the angle you need to apply serious torque on tight or corroded pedal threads. The long, ergonomically shaped handle generates enough leverage to remove the most stubborn pedals without strain, and the hardened steel construction means this wrench handles daily shop use without wearing out.
Pedal installation and removal should never be a fight. The PW-4's thin wrench head fits into the narrow clearance between the pedal axle flats and the crank arm, making it the tool that gets the job done where a thicker wrench simply won't fit. For shops putting pedals on and off all day, this is the wrench that belongs on the bench.

Good questions
Get to know Park Tool

There's more to Park Tool than this one product. Our Park Tool page has the full Park Tool lineup we carry and more about the brand.
Visit the Park Tool page →What size is the PW-4 pedal wrench?
The PW-4 is a 15.0mm pedal wrench, which is the standard size for the vast majority of bicycle pedals.
Why is a thin wrench head important for pedal removal?
The clearance between pedal axle flats and the crank arm is narrow. A thin wrench head like the PW-4 fits where standard wrenches cannot engage properly.
Is the PW-4 suitable for home mechanic use?
Yes. The PW-4 is professional-grade but entirely appropriate for home mechanics who want a proper pedal wrench that will last for years.
