I need to switch out my 7-speed cassette. My LBS has a 13x30 SRAM and a 12x32 Shimano cassettes in stock. I need to decide which one or have him order something else.
I'm familiar with the quality of Shimano but know nothing about SRAM cassettes. I do have an SRAM chain. Anyone have any issues with SRAM cassettes?
How about the difference between 12 or 13 teeth? I know it depends on the front ring but is there a significant difference independent of which ring you're on?
It depends on how fast you like going. If you have some hills or like to fly on the flats, you might spin out with a 13. You got to be going really fast to do that but I've come close to wishing I had an 11 on some downhills.
