The chain on your bike slowly wears out as you build up the miles by getting stretched longer and longer. A chain wear tool is a quick and handy device that will tell you when your chain needs replacing. If left for too long a stretched chain will begin to wear out your chainrings and could result in poor performance from gear changes and even be potentially dangerous if the chain 'slips'. A worn chain can skip over the top of the cogs to cause 'skipping' or 'slipping' gears.
The Ribble R-CWT is designed to give you an instant and accurate guide to indicate how much your chain has worn.
Simply by seeing if the tool drops into your chain or not (no pressure is required so don't push it in further than it drops), you can tell if the chain (0.75 on the tool), or both the chain and cassette needs replacing (1.0 on the tool). This is a small toolbox esential that could save you money in the long term. Keep replacing your chain regularly and it should work with your existing cassette, but leave it too long and the stretched chain will have caused excessive wear to the cassette and both chain and cassette will need replacing.
NB when measuring ensure that a Power, Master or Quick link is not included in the section of chain being measured.

Must have in your toolbox
I already had a chain wear tool, but you can get some movement on it, giving different readings.
This is very simple to use to check your chain wear, no ambiguity.
Tells to you whether your chain:
a. Is okay
b. Needs replacing
c. You've left it too long and may need to replace your cassette and chain rings.

This was another piece of kit I needed but have never quite got to. If you are thinking of getting into doing your maintenance yourself then this is a really important piece for the work bench
