The Crank Brothers Multi 17 tool is well constructed and very high quality. It is possibly the best multi tool ever made and an Excel Sports staff favorite. It features 17 of the most important hardened-steel tools required to fix almost any trail or roadside mechanical or needed adjustment - including an ingenious chain tool that works for 8, 9, or 10-speed chains. The Multi 17 has a flat profile with no protrusions and fits into the smallest packs. Works great for road or mountain. Makes a great gift.
