The UNIOR Sprocket Wear Indicator 2023: BLACK HG-IG is a precision tool designed to accurately assess the condition of rear sprockets ranging from 12 to 21 teeth. Crafted from premium flex plus carbon steel with a chrome-plated finish adhering to ISO 1456:2009 standards, this tool ensures durability and reliable performance in any workshop setting. Its compact dimensions make it easy to handle while delivering precise measurements critical for maintaining optimal drivetrain performance.
Using the indicator is straightforward and efficient. By placing the chain on the sprocket and positioning the tool’s round end between two teeth on the upper sprocket side, you can apply a controlled force of 100 N (10 kg) to simulate sprocket rotation. This method reveals whether the sprocket is still in good condition or showing signs of wear that could affect chain engagement and overall bike functionality. Early detection of sprocket wear helps prevent further drivetrain damage and ensures smooth, safe riding experiences.
Ideal for both professional mechanics and cycling enthusiasts, the UNIOR Sprocket Wear Indicator supports maintenance of HG and IG sprockets with precision. Its robust construction combined with user-friendly design makes it an indispensable addition to any workshop toolkit, providing confidence in sprocket condition assessments and timely replacements.
How do I know when to replace my sprocket?
If the last chain link gets stuck on the tip of the neighboring tooth or requires force to skip onto the cog, it indicates wear and the sprocket should be replaced. If the chain falls off when force is applied, replacement is urgent.
Is this tool compatible with all sprocket types?
This indicator is designed specifically for HG and IG sprockets with 12 to 21 teeth, ensuring accurate wear assessment within these specifications.
