Derailleur systems have over the years added more and more gears to the clusters. A few years ago 8 speed was cutting edge. Now 9speed is standard for mountain bikes, and road bikes have hit 11 speed. Initially extra gears were accommodated simply by adding more cogs to the cluster. Making the wheels wider and dishing them more squeezed on another gear. 9speed and above needed thinner cogs, and ever narrower chains.
If you read the reviews on 8 speed chains, there are virtually no complaints about chains snapping. Read the reviews for 9speed chains used on mountain bikes and you get problems with chains snapping. They typically break under low pedalling pressure, and after the chain has been in use for a few months. I have not read a satisfactory explanation as to how a chain could snap like that. You can not break a chain simply by ...
OK, let's start by clearing up one thing here which I bet at least 90% of the people reading this review will be asking: What's a cassette?
Well, a cassette is one of those incredibly boring things on a bike that doesn't look posh, and which your average bike owner would probably never even think about buying. So, take a look at the back wheel of any geared mountain bike or road bike. See that set of between five and nine cogs? That's a sprocket cluster or cassette.
So, why would anyone buy such a thing? Simple. A bike in regular use gradually deteriorates, and the drivetrain (front and rear cogs and chain) is no exception. The chain stretches, and this causes the teeth on the cassette to wear down. This eventually leads to the chain jumping under load, and until I could manage to get the money together to buy a new ...
