Birzman's Chain Wear Indicator is a really simple way of telling whether any chain from singlespeed to 12-speed should be changed, and it doubles up as a chain hook to help hold your chain during assembly or repair. 

Your chain will gradually wear. What difference does it make? Worn chains can skip, shift poorly and sometimes break – which can be dangerous. A worn chain will also wear sprockets more quickly than usual, so changing it in good time will save you money in the long run.

You can check for chain wear with a ruler but it's easier with a chain wear indicator. Birzman's is CNC machined from stainless steel and has a hook at one end that slots in next to a link pin.

There are three indicator prongs at the other end. If none of them falls into a gap between rollers (as in our photo) and is visible out of the bottom, your chain isn't 0.5% longer than its original length. The chain in our picture is one ride old, so that makes sense.

If the tallest prong drops through, chain length has increased by 0.5%.

If the middle prong drops through, chain length has increased by 0.75%.

If the shortest prong drops through, chain length has increased by 1%.

The figures are marked on the chain wear indicator; you don't have to remember them!

> Find out when you should replace your chain

Different chains need replacing after different amounts of wear, hence the three prongs.

If you're using an 11-speed or 12-speed chain, for example, you should replace it when it is 0.5% more than its original length.

If you're using a singlespeed chain, you need to replace it when it gets to the 1% mark.

> Beginner’s guide to bike tools

Measuring less than 14cm nose to tail, it's a bit shorter than a Park Tool CC3.2 Chain Checker that I have here (17.5cm), but that's probably not an issue either way. The Park Tool device has similar 0.5% and 0.75% indicators, but there's no 1% marker.

One other feature that the Birzman Chain Wear Indicator boasts is a chain hook. Say you're putting a new chain on your bike: you can use it to hold the ends of the chain in position without the links that you need to work on being pulled away from one another. A bent spoke can do something similar, but it's not nearly as posh. It's a simple job that the Birzman tool does well.

A chain wear indicator is the sort of thing that you'll buy once and only need to replace if you lose it or someone comes out with a new chain standard. The Park Tool CC3.2 Chain Checker that I mentioned earlier retails at £9.99 while Topeak's Chain Hook and Wear Indicator is £6.99, so Birzman's is a good price.

Overall, the Birzman Chain Wear Indicator does its job well across a whole range of different chain sizes, and the integrated chain hook is a handy little bonus.

Verdict

Simple tool that measures the amount of wear across a range of different chains, with an integrated chain hook thrown in
