Aluminum Alloy Single-Chainring Wear Tool CNC Machined Anodized Blue

Made from aluminum alloy, this bike tool combines a lightweight feel with a rigid structure for everyday workshop use. Designed as a chainring gauge, it serves as a bike chainring measurement tool for checking single-chainring wear and comparing chain profile. The compact flat plate shape, cutout openings, and multiple mounting holes make this single-chainring wear tool easy to handle and practical to position. CNC machining and anodized blue finishing give this chainring wear checker a clean, precisely cut surface with a clear printed model-328 model marking. Built to help assess chainring condition quickly, this tool supports routine wear checks so riders can inspect parts before performance drops.
