Sorry but another in a long list of bike maintenance questions I'm likely to have.
The story so far is I splashed out for a new wheelset. Then it was suggested I get a new cassette for quick and easy swapping of wheels. Made sense so I picked up a 9 speed ultegra 6500 cassette, some tools etc.
I was bragging to a mate about my shiny new purchases that are winging there way here an he says you'll need a new chain as well. I say 'doh' do some googling and it turns out he was right.
So my questions are, what chain should I be on the lookout for (I'm guessing 9 speed shimano, but there are many differing types) and do I need anything in particular to install it. I have no doubt there will be some special tool I need.
Thanks
Andrew
