A road cassette surely? Why would you need a 32 on a 4x bike?
Get some sort of 11/25 road cassette, like an ultegra or eve durace if its in your budget.
Thanks. Think I will go for the 11-34 XT cassette. I'm running a 36t/26t up front so loosing another 2t off the rear will be too much.
No one recommending SRAM or any others?
