SRAM PG970 MTB 9 Speed Cassette

Its a snap for this Powerchain

Advantages: Cheap, shifts well, excellent joining link
Disadvantages: Can suffer chain breakages

-snap-snap Derailleur systems have over the years added more and more gears to the clusters. A few years ago 8 speed was cutting edge. Now 9 speed 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. 9 speed and above needed thinner cogs, and ever narrower chains.

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 ...
