8 or 9 speed Shimano 12-21 or 12-23 (ideally) cassette

[Slimtim]

I am looking for a cassette to help with a TTing go faster experiment.

8 speed ideally but 9 speed also OK.

Don't want to spend the earth due to the experimental nature of my plan!

I have a shimano 9 speed 12-23 you can have for £10 posted, been used but plenty of life left.

That sounds great. I have dopped you a PM ref payment.
