The F-tools from Crankbrothers are a compact multi-tool set that sets a new standard. With a thin and lightweight body, these tools are perfect for keeping you going on the trail. The F-tools have a magnetic case that not only secures the tools but also provides a larger handle and extra leverage. This makes them easy to use and gives you the power you need. The set includes a range of hex wrenches in sizes #2, 2.5, 3, 4, 5, 6, and 8. There is also a Torx wrench in size T-25 and screwdrivers in both Phillips #2 and flat #1. For wheel maintenance, the F-tools come with spoke wrenches in sizes #0, 1, 2, and 3. There is also a chain tool that is compatible with 8, 9, 10, 11, and 12-speed chains. And for those well-deserved breaks, there is even a handy bottle opener included. With a warranty of 5 years, you can be sure that these tools are built to last. And weighing just 164g, they won't weigh you down on your adventures.
