Sram 10-42 Cassette with Shimano Di2????
I'm running SRAM force 1 mechanical 1x on the road and it's perfect for where and how I ride. 42 up front and 10-42 rear. That gives me the range I need at 27" to 113". I'm trying to figure out how to make this work electronically. The new Shimano 11 speed GRX Di2 is almost there but the cassettes all start with an 11T cog and this won't give me the top end at only 103 gear inches. Not interested in running the Sram 50T MTB cassette. The new SRAM AXS is all cross compatible but the road cassette tops out at 33T and then you jump to the MTB 50T. I don't believe the 12 speed AXS chain, derailleur etc will work with the 11 speed 10-42 cassette. Only thing that seems possible is going Frankenstein and seeing if the Di2 can be programmed to work on the SRAM 10-42. They claim 11T is smallest cog it will accommodate. Any experience actually running this setup? And SRAM, lots of people really love your 10-42, where is the AXS compatibility???
