Pack Wrench

Wolf Tooth's Pack Wrench is an innovative bike tool that has a 1in hex driver on one side, a standard external bottom bracket wrench on the other, and is compatible with a multitude of other tool inserts that lock into place magnetically. The ultralight aluminum construction is specifically designed for traveling with your bike for mobile wrenching or tossed into a pack for trailside repairs, but is sturdy enough to be your go-to tool at home as well. No inserts are included, but Wolf Tooth makes a number of useful ones that cover a fairly broad range of road and mountain bike applications. To ensure quality and longevity over many years of use, Wolf Tooth designs and manufactures the tool in Minneapolis, MN, USA.
