Need to replace my chain and cassette. HELP
For the past couple of rides i've had a bit of noise coming from the cassette whilst pedalling, i've adjusted the derrailers and had little improvement. think the cassette and chain need replacing.
I have no idea what i'm doing.
Here's the spec of the bike: http://www.evanscycles.com/products/genesis/aether-20-2011-road-bike-ec0...
I assume its a 9 speed chain and cassette i need so im considering an ultegra cassette and tiagra chain. i think. What tools do i need to complete this? Am i making the correct assumptions?
Ill be fine doing the work, i can just find a how-to video somewhere. I think GCN posted on a while ago.
Cheers in advance!
