This device lets you know instantly when it’s time to replace the chain – before the worn chain accelerates the wear on your (more-expensive-than-a-chain) chainrings and cogs.
- The CC-3.2 lets you know when the chain has ‘stretched’ by 0.5% and 0.75% – the point when most chain manufacturers suggest replacement.
- If the 0.75% side fits into the chain, the chain is worn to 3/4 of 1%, so the chain should be replaced soon.
- The updated CC-3.2 is longer, more accurate and features permanent measurement markings.
- Very simple to use – you can check your chain in literally one second with the CC3.2.
- Made from precision, laser cut steel.
- Fits all 1/2-inch-pitch chains, including 10-speed chains.
