CONTEC Chain wear indicator TFP-Wear Detector

In the worst case scenario, an unnoticed worn chain can ruin your cassette and chain rings. That's why the CONTEC chain wear indicator "TFP-Wear Detector" made of robust steel is exactly the right companion for your regular maintenance.

It reliably measures all chain wear for 1-13-speed chains. This also includes SRAM T-Type, Flattop and SHIMANO XTR 12-speed chains.
The integrated chain hook is your helping hand to make it easier to connect open chains. You can see when you should replace your chains in our list:

- 1-speed chains: Replace at 1% elongation
- 5-10-speed chains: Replace at 0.75% elongation
- 11-13-speed chains: Replace at 0.5 % elongation.
