I am working on a new gravel build and was going to make it a 1X mullet but I am really not a 1X fan for gravel - I know that is a sensitive subject but I am definitely building this bike 2X. I ride a lot of road to get to my gravel and this build is being designed for both.
I think the below list will work but I'm concerned about the AXS cassette and chain compatibility:
- Easton 36/40 Chainrings
AXS Force 10-36 Cassette
KMC X12 Chain???
SRAM X0 10 Speed Rear Derailleur
SRAM Force 11 Speed Road Shifters with Ratio 12 Speed Upgrade Kit
I called Easton and their 2X chainrings are not flattop compatible so my first concern is running a standard 12 speed chain - like the KMC X12 - on the AXS cassette. I have heard there has been some success with this but hoping for additional feedback - anyone have any success or failure with this?
If the chain is indeed compatible I am thinking of installing the Ratio 12 speed upgrade kit and using a long cage 10 speed SRAM XO rear derailleur (with exact actuation) that I currently have. Ratio kit is here if anyone is interested. Black Water Cyclist on YouTube has had come success with this but that just one source, albeit a pretty good one...
Any feedback on what I have planned would be much appreciated.
