The f-tool is a new option in the Crank Brothers range, and it offers a very slim and minimalist aesthetic for those riders who prefer less bulk. Each F series comes with hex wrenches: 2, 2.5, 3, 4, 5, 6, 8, screwdrivers: Phillips #2, flathead #1, spoke wrenches: 0, 1, 2, 3 and Torx t-25. The F10+ comes with the aluminum case and the F15 includes the case and also has a chain breaker. All are made from stainless steel construction for a durable and lasting multi-tool.
