Ice Toolz 15mm Pedal Wrench With Ergonomic Handle This pedal spanner's textured, vinyl-coated ergonomic handle does indeed offer a more comfortable hand hold and better grip. The wrench is made in CrMo steel for longevity. Fits almost any conventional pedal - as long as it has 15mm flats were it meets the crank arm. The Ice Toolz 15mm Pedal Wrench's off-set design offers more leverage than a conventional straight spanner. We've learned to appreciate Ice Toolz quality over many years. With its impressively deep 15mm jaws this pedal spanner should last a lifetime of home wrenching.
