Pedal flats stick to the crank with surprising determination, especially when corrosion or thread sealant has had time to work. The Park Tool TWB-15 crow foot adapter lets you attack seized pedals with a torque wrench or breaker bar, bringing serious leverage to a job that defeats standard pedal wrenches. The 15mm opening fits the wrench flats on nearly every pedal spindle, and the 3/8-inch drive accepts any ratchet, breaker bar, or torque wrench with a matching square drive.

Crow foot adapters change the geometry of your torque wrench, which matters if you're installing pedals to a specific specification. When the crow foot extends the effective length of the wrench, the actual torque delivered differs from the readout. Park Tool includes the math in the documentation, but the short version: measure from the torque wrench pivot to the center of the crow foot, compare that to the original wrench length, and adjust your target accordingly. For removal, this is irrelevant—you're just trying to break the pedal loose, and more leverage is always welcome.

The TWB-15 works particularly well paired with the SWB-15 breaker bar for stubborn removals. That 15-inch handle generates enough force to break free pedals that have been in place for years. For installation, use a quality torque wrench and account for the crow foot offset to hit the manufacturer's recommended specification without over-tightening. The thin profile of the crow foot head fits into tighter spaces than a standard pedal wrench, which helps on frames where the crank arm sits close to the chainstay.... Read More
