Changing a cassette

Chewy Cheeks

I need to change rear cassettes, from one wheel to another.

Happy to be directed to a good website.

I am not a fettler so I need simple instructions.

Thanks

It's a straightforward job, but you will need a couple of special tools: a chain whip and a lockring tool. The chain whip holds the cassette in place while you take the lockring off with the lockring tool and a big spanner (you want to turn the lockring the same way the cassette spins). Once the lockring's off the cassette should just slide off.

It might need a bit of grunt to shift the lockring, and watch your knuckles!
