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?
