| For most normal people yes it's necessary to change both. Change just the chain and you'll quickly
| realise why. I've come to the conclusion that unless you've got a really expensive and hard
| wearing cluster, you may as well change them both at the same time and thus get more wear out of
| the chain.
|
| e.g. my chain cost 28 euros and my cluster cost 51 for a grand total of 79 euros. I got around
| 15,000 km out of them. Had I changed the chain every 5,000 km, maybe I could have
| optimistically gotten 30,000 km out of the cluster.
|
| 6 x 28 + 51 = 218 euros = more expensive.
|
| or even every 10,000 km - doubtful whether I'd get 30,000 km out of the cluster though.
|
| 3 x 28 + 51 = 135 euros = cheaper.
|
| or the lazy way:
|
| 2 x 79 = 158 euros. Less resource intensive.
|
| To save even more euros, I could clean the chain a bit more. Don't like to do that unless I can
| avoid it i.e. it rains/hails/snows.

Isn't a Euro a small kangaroo? That's a lot of kangaroos for a chain.
