Cyclo Chain Wear Indicator
This tool is something that I have never used before. It's interesting having a tool that indicates chain wear rather than judging it by time or season. The instructions included clearly explained how to use the tool and were useful as it would have taken some time to figure out exactly how to use it. The tool is simple to use. It is double sided indicating different degrees of wear (or non wear). It is slightly sharp around the edges so gentle handling is a must!
At £5.99 it is good value for money: a one time investment.
Personally I don't see the need for this tool as I tend to just replace my chain every now and again when I see evidence of wear. My drive train tends to be in the middle of the range so the cost is not so great that I feel that I need to monitor wear that closely.
For those who will use it I think this product does what it says. It seems a bit basic but it isn't necessarily a bad thing as it functions fine. It is however quite sharp on its edges and I'm sure smoother sides wouldn't go a miss.
Overall I would say for that someone who is likely to use this product I would give it a 6/10.
