The Park Tool IB-3 Multi-Tool is a comprehensive bike tool to take with you, combining our award-winning I-beam design with a full range of 15 emergency tools. The IB-3 includes virtually every tool you might need for most trailside repairs. It includes eight hex keys, a T25 Torx-compatible driver, and a flat-head screwdriver for on-the-fly adjustment of brakes, handlebars, saddle, or derailleurs. The integrated chain breaker is useful for emergency chain repairs and can also be used for complete chain removal and installation. The composite-coated tire lever can be a lifesaver when dealing with a flat tire and includes integrated spoke keys for triage of loose or broken spokes.
