Why We Like The 8-Bit Chainbreaker + Utility Knife Multi-Tool

It's a chainbreaker and utility blade in one, and it's the 8-Bit Chainbreaker + Utility Knife Multi-Tool from Wolf Tooth Components. This is the brand we trust for quality components and bike maintenance needs, and this multi-use tool is cleverly designed for versatile use. It's designed to work on its own or be grouped with other 8-Bit System multi-tools to solve most trailside problems and get us where we need to be.
