This unusual disassembling design actually works pretty well and saves precious grams for weight-conscious riders, coming in under 100 grams while featuring two tire irons, allen, screwdriver, torx bits, and a bit-holder. Since you can use each individual bit without dealing with the whole system, it's a little easier to use than a classic bike multi-tool.
