Made from Cro-Moly steel for a shop quality pedal wrench made to last. 15mm and 9/16" precision openings and a long, round, vinyl dipped handle that won't dig into your hand like flat pedal wrenches. The PW-3 is nominally 32cm (12.5") long. (NOTE: The 9/16" wrench flats are found on some older bikes with one-piece cranks.)
