ROHLOFF HG-Check P-16T Wear Indicator for Shimano Hyperglide Sprockets
The ROHLOFF HG-Check P-16T is a wear indicator designed to assess the condition of Shimano Hyperglide sprockets. It helps prevent chain slippage during rides, especially before races or chain replacements. The tool is used by placing it on each sprocket and checking if the measuring roller moves freely into the tooth gap. If resistance is felt or the roller hits the tooth tip, the sprocket is worn and should be replaced. The manual includes instructions for use with 12-21 tooth and 11/12-speed cassettes, with different handling methods for each.
The device is compatible with Rohloff 9-speed or Shimano 10-speed chains, suitable for up to 10-speed or 11/12-speed cassettes respectively. It includes a handle and measuring roller, and users must clean sprockets before testing. The manual is multilingual, with instructions in German, English, and French. This manual is written in German.
