Use A Pedal Wrench When It Just won't Fit - Bike Repair

I know the feeling. You take that old bike out of the barn and your eye focuses on the decomposed pedals. That should be an easy fix, you think. Your toolbox has a pretty beefy crescent wrench. Should be a snap to get those old pedals off.

Oh, no. It just won’t fit. The jaws are wide enough but there isn’t enough space between the pedal and the crank arm to get a grip.

Even after you obtain a proper pedal wrench for the proper job, you may find pedals on an old bike are so frozen you can't budge the buggers.

Get your buddy to hold the bike firmly on the ground. Fit a piece of pipe over the tool to increase the fulcrum and give it heck.

You’d better have that bicycle on solid ground if you’re going to use a pipe or it'll be too unstable.
