Chain Wear Indicator

Chain stretch is cumulative, and once it hits 0.8%, the chain begins to physically damage your cassette and chainrings. Replacing the chain at this specific threshold prevents that accelerated wear, saving you from having to replace your entire drivetrain prematurely.

While this tool is specifically optimized for SRAM chains, including those with HARD CHROME technology, it is designed to measure standard chain pitch. It will generally function on most standard bicycle chains, though it is engineered with SRAM's specific tolerances in mind.

For the average rider, checking your chain every 500 to 1,000 miles is a good rule of thumb. If you ride in particularly gritty, muddy, or wet conditions, you should check it more frequently, as these environments accelerate chain wear significantly.

Yes, this tool works with SRAM e-bike chains. E-bike drivetrains are under significantly higher torque loads, which can cause chains to stretch faster than on standard bikes, making regular checks with this tool even more critical.

No, the tool measures the elongation of the chain links, which is consistent across different speeds. Regardless of whether you are running an 11-speed or 12-speed setup, the 0.8% wear threshold remains the universal indicator that your chain needs to be replaced.
