A magnetic aluminum case holds the Crank Brothers F15 together and transforms how you use a multi-tool. The three-piece design splits the folding tool body, chain breaker, and spoke wrench into separate components that snap into the brushed case via magnets. When you need to use a hex key or break a chain, the case becomes a handle that delivers leverage you can't get from a traditional multi-tool. This means you can actually remove pedals or cranks trailside without resorting to pliers or compromising your grip.

The hex key selection covers 2mm through 8mm in seven sizes, plus a T-25 Torx bit, Phillips #2, and flathead #1 screwdriver. The 8mm hex is hollowed out to shed weight while maintaining strength for pedal and crank bolts. Each bit fits precisely in fasteners without the slop that rounds bolt heads, and the SCM435 stainless steel construction resists wear from repeated use. The chain tool handles 8-speed through 12-speed chains for breaking purposes, with the forged steel body providing rigidity that prevents flex when you're pushing pins out. Four spoke wrench sizes (#0, 1, 2, 3) sit on the opposite end of the chain tool component.

The compact dimensions measure 84mm long by 40mm wide by 16mm thick when fully assembled. This slim profile slides into jersey pockets or frame bags without creating bulk, and the rounded edges prevent snagging on fabric. You can separate the folding tool body from the case for weight-conscious rides where you only need hex keys, leaving the chain tool and case behind. The strong magnets keep components locked together during rough riding, but release easily when you need to access a specific tool.... Read More
