Crank Brothers Multi-Tool 17

CrankBrothers Multi-17 Tool features both a chain tool and a disc-brake-rotor-friendly Torx T-25 wrench alongside the usual package. The Crank Brothers Multi 17 Tool has mountain bikers first in mind. Nothing besides a flat or a broken bone will stop your ride as quickly as a busted chain, and if you ride hard you're bound to snap a link sometime. The Multi 17 might not be the absolute lightest tool or smallest on the market, but the extra grams are well worth it because if you don't have the right tool when the chips are down, you're dead weight anyway.
