The Ultralight Pack Wrench and compatible inserts are designed to provide a bike tool solution that is compact and lightweight enough to carry with you on the road but still be durable enough for everyday use. The aluminum wrench has magnets that hold the nickel-plated steel inserts in place. The wrench has splines for bottom brackets and centerlock rotors and the four included inserts cover most common bike applications.
