The 8-Wolf Tooth Components 8-Bit Chainbreaker + Utility Knife Multi-Tool is a compact, four-in-one trail essential built for quick fixes and smart storage. It combines a chainbreaker, a retractable utility knife, a tire plug inserter, and a 16mm crank bolt tool-all housed in a slim aluminum body designed for durability and ease of use. The chain tool is activated by a removable 3mm L-hex key, which also doubles as the tire plug inserter. The multi-tool&';s handles slide open to reveal internal storage for tire plugs, a valve core, and spare blades, keeping everything protected and organized. The 16mm hex head adds extra utility for tightening crankarms when you&';re out on the trail. Part of the modular 8-Bit System, this tool can be used alone or paired with other 8-Bit tools via its magnetic nesting system. Like all Wolf Tooth tools, it&';s machined in the USA from high-grade aluminum and designed to be lightweight, tough, and jersey-pocket ready.
