After a 10 speed 11-42 cassette for sram gx As anyone tried https://www.ebay.co.uk/itm/144120295886 or https://www.ebay.co.uk/itm/373378099765 at t he moment i’m on sram 10 speed: Cassette (PG1030) 11-36T with a 42 extended ring which a the moment works out at about £80/£90 but the two above £20/£25 i know they wont shift as good or last as long but at them prices i wouldn’t mind changing more often
Thanks for any help…

I’ve used ZTTO stuff and it’s fine. Quite good actually, so at that money it’s a bargain.

Spa Cycles have Shimano and Sunrace 11-42 cassettes in stock sensible prices.
