ive just used the chain checker tool and i need a new chain ive had bike for a yr now and done about 2600 miles,do most chains need replacing about now then, and do i just need to put the chain on and dont need to alter anything
If you change the chain regularly then a new cassette is not necessary. I have a Sram cassette that is over 3 years old and I have changed the chain 3 times with no gear slipping problems.
Just to add. Roughly how often should you change your chain? Mine's probably well over due.
When it's worn and before it starts to wear your cassette/chainrings.
(my last change wasn't done on any scientific grounds, i just thought, that feels/looks (nudged it/prodded it (with my fingers!) round the chainring) worn and decided it to change it. Felt much much better afterwards.
Andy. Do you mean your old chain is not slipping yet. If the old one starts slipping you are way past needing a new one and will definately need a new cassette. If you have fitted a new one and it is not slipping you are OK.
If your chain checker is just up to the renew mark I would do so as you will probably get away with the cassette. Then ride in the gears you use most and see if it works OK. It may make a little more noise than before but if it shows no sign of slipping then go with it. The noise will settle down. I usually get 3 to 4 chains to 1 cassette. I use Dura-ace chains with Ultegra cassettes as I find that they last longer and have been cost effective in the long run. My last cassette did about 11000 miles on my summer bike followed by 3000 on the winter one. Probably 5 chains.

no, he might not, Andy, inspect the teeth on your cassette as per this http://www.sheldonbrown.com/chains.html
