It contacts the chain in three places, eliminating guesswork. Compatible with 5 to 13-speed and single-speed chains, it indicates wear at 0.5%, 0.75%, and 1.0%, matching manufacturer replacement recommendations. - Measures bicycle chain wear accurately, preventing expensive drivetrain damage - Laser-cut design contacts the chain at three points, providing quick and precise wear measurement - Compatible with 5 to 13-speed derailleur chains and single-speed chains - Indicates chain wear at 0.5%, 0.75%, and 1.0%, aligning with manufacturer recommendations for replacement

The updated CC-3.2 is longer, more accurate and features permanent measurement markings.
