I don't have much use for my 50x12 and a 34x27 would help with climbing. So, a couple questions.....does anyone make a 13x 27? Will a Shimano cassette work with my SRAM setup?
As noted in prior posts, there are numerous options for cassettes with a low cog of 27 or more. However, you need to check the capacity of you current RD. If you go from 25 to 27,or more, you may need a different RD. Since you have SRAM, I recomment their WiFLi (
