Thank you for your reply, yes I do need the gears as I live in gloucestershire!
I will look into Shram 12-26 teeth.
I use a SRAM PG850 12-26 for cyclo-cross and they are well-made, light cassettes that work well. Something similar but cheaper from Sunrace is available from a few eBay sellers; it's a little bit heavier and the plated finish isn't as shiny as the SRAM stuff but otherwise a nicely-engineered budget cassette that shifts well:http://www.ebay.co.uk/itm/SUNRACE-8-SPE ... 5657a443d4
(I've got the 11-23 version on my road bike)
