Overview
Does the Crankbrothers F15 have everything you need for a road or gravel ride?
Yes, and it covers trail rides too. The F15 packs 15 tools into a slim magnetic case that weighs just 164g: hex wrenches from 2mm to 8mm, a T-25 Torx, Phillips and flat screwdrivers, four spoke wrenches, a chain breaker compatible with 8 through 12-speed drivetrains, and a built-in bottle opener. The magnetized case holds every tool securely in place and doubles as a handle, so you get real leverage when you need it, not the wobbly grip you get from a traditional folding multi-tool.
At 84mm x 40mm x 16mm, it disappears into a jersey pocket or saddle bag without a trace. The minimalist profile is intentional . Crankbrothers designed the F15 for riders who want maximum capability with zero bulk. If you have ever cracked a spoke, broken a chain, or needed to dial in a saddle mid-ride, this is the tool that handles all of it without making you carry something that feels like a brick.
