Chain Wear Indicator II

The Chain Wear Indicator 2 lets you know exactly what state your bike chain is in. The user-friendly chain wear gauge checks the degree of chain wear and stretch and shows you when it's time to replace the chain. Thanks to the differentiated scale of the degree of wear, it is compatible with all current chains – no matter whether classic single-speed or highly modern 12-speed derailleur chain.

Details:
• Material: CNC milled 6061 aluminium
• Compatible with single-speed as well as 5 - 12-speed derailleur chains
• Wear indicator: 0.25/ 0.5/ 0.7/ 0.8/ 1.0%

Chain replacement recommended at:
• Single-speed: ≤ 1.0
• 5 - 8-speed: ≤ 0.8
• 9 - 10-speed: ≤ 0.7
• 11 - 12-speed: ≤ 0.5
