Titan Chain Wear Indicator
Stay ahead of the game with the Titan Chain Wear Indicator. Poor shift quality and premature wear can be associated with a worn chain. A Chain Wear Indicator informs you that your chain has stretched beyond the manufacturer's recommended specs. Replace it before it reaches that point with the Chain Wear Indicator. This tool is very intuitive; you place one end in a link and then try to see if the other end slips in another link. If both ends fit the chain has stretched and needs to be replaced.
Good cheap way to check your chain wear rather spend money on this and chain than new cogs
This is easy to use comes with instructions and can save your Cassette and front chain rings from an early demise due to riding a stretched out chain. It's a must have for someone who puts in a lot of miles.
This is a must have tool if you are in to bikes, its cheap and accurate.
Easy to use and doesn't take up much space. Now I don't have to wonder when it's time for a new chain.
Gadget takes the guesswork out of chain wear; simple to use go-no-go style fits just about anywhere & with no moving parts it's pretty hard to make it wear out. Also easy to clean after checking that nasty chain prior to cleaning (a waste of time if the chain is dead anyway).
For the price very worth having. With drivetrain being so important. This neat little tool is used in seconds. I thought of changing my chain sooner. But now I feel confident when to with this.
