Birzman 链条量规 silver

Chain wear is not obvious, but it has a negative effect on the durability of the sprockets and chainrings, so that these too have to be replaced sooner. With the Birzman Chain Wear Indicator, chain wear can be determined quickly and reliably so that the chain can be replaced in good time. The chain wear gauge shows a chain elongation of 0.5, 0.7 and 1.0%. Compatible with 1 to 12 speed chains.
