Hi, i am going to try and build a mountain bike, i have brought the frame and i am confused what rear cassette i would need and what type of chain i would need to but on the bike, i am going to use the bike for everyday use on pavements and i sometimes like to go up hills in high gears. The bike is going to have 24 gears, so what chain would i need? and what cassette speed and size would i need?. Many thanks.

Or could i have this http://cgi.ebay.co.uk/Shimano-Chain-and-Cassette-9-Speed_W0QQitemZ350267376966QQcmdZViewItemQQptZUK_sportsleisure_cycling_bikeparts_SR?hash=item518d900546

Would any of these be ok?
 
Unless you want to go real high performance or expensive, an 8 speed 13-28 cassette in the rear, an 8 speed chain and a 3 speed 28-38-48 crankset are the default choices.

The 9 speed above has much better gearing.
