Velo CT Wear Gauge
The Renold Velo CT wear gauge has been specifically designed to accurately measure chain elongation without the need to remove it. To avoid problems with running, the chain should be replaced before elongation reaches 1%.
The wear gauge itself has a unique serialisation number commemorating the 138 years that have passed since Hans Renold himself patented the bush roller chain design we know today.
This assessment of chain elongation has now been made quick and easy with the Renold Velo CT wear gauge and this simple maintenance step can improve efficiency and performance by replacing your chain when it is required!
