I've just ordered new cassettes as well a SRAM 1130 11-36 for the GT Grade and a SRAM 1030 11-36 for the BMC Alpenchallenge. They are reportedly compatable with Shimano. I've also ordered a 48t chainring for the GT Grade. That will give me identical gearing for both bikes apart for the little ring on the BMC.
GT Grade
48/36 11-36
BMC AC02
48/36/26 11-36
I'm not sure what bike I'll be using. But if I don't have the gearing for the hills I am seriously in trouble
TB,. SRAM work with Shimano no problems. Your triple setup has the same gear inches as my bike on the easiest gearing. It allows me spin up 20+% hills.
