The Shimano Carrier Unit Gear Align Tool is a purpose-built workshop tool designed to help mechanics and home tinkerers precisely align gear-related carrier units in Shimano systems. By providing a stable, accurate reference, this tool makes it easier to diagnose and correct alignment issues that can cause poor shifting, noise, or premature wear. Its robust construction is made to withstand repeated use in busy workshops, while the carefully shaped interfaces are engineered to fit Shimano components securely and consistently.
Ideal for professional mechanics, shop technicians, and advanced home users, the Carrier Unit Gear Align Tool helps ensure that drivetrain components are correctly positioned relative to each other. This leads to smoother gear changes, better overall performance, and reduced risk of damage to expensive parts. Because it is designed specifically around Shimano standards, it integrates naturally into existing service procedures and complements other Shimano service tools. Whether you are building up a new bike, servicing an e-bike drive unit, or troubleshooting shifting problems, this tool adds precision and confidence to your workflow.
