Details

• Accurate measurement of chain wear: Don’t let a worn-out bike chain ruin your ride. With this bike chain tension gauge, you can quickly and accurately measure chain stretch and decide in good time when the chain needs replacing – for smooth and reliable gear changes.
• Compatible with 7–12-speed bicycle chains: This chain stretch gauge reliably measures whether your bicycle chain has reached a stretch of 0.75% or 1.0%. Compatible with chains from Shimano, SRAM, Campagnolo, KMC and other brands – ideal for modern road bikes, MTBs and hybrid bikes.
• Easy to use: Simply place the Chain Checker on a link of the bicycle chain. If the tool lies completely flat on the chain, the chain should be replaced. If the tool stands slightly upright at the 0.75% end, the chain can still be used.
• Robust professional quality & compact design: This precision laser-cut bicycle tool is made from durable, high-quality material and has been designed to last. Thanks to its compact size, it is easy to carry and perfect for the workshop or tool bag. Length: 140 mm | Weight: 32.8 g.
• Protects the cassette and chainrings: A heavily worn chain can cause expensive components such as the cassette and chainrings to wear out more quickly. Regular checks using a chain tensioner prevent shifting problems and save money in the long run, as only the chain needs to be replaced in good time.
