What would be a good touring cassette.
I have a Trek FX 7300 and it has a 11-30 cassette and the chain rings are 48/38/28. I want to change the cassette out to either 11-32 or a 11-34. Which one would give me a noticeable difference. Also I was told that the Shimano cassette was better than the Sram because the Shimano doesn't wear out as fast. Thanks for any replys,George
