46T option for a Tiagra 4700 2x10
Do you have any suggestions for 46T big ring that fits a Tiagra 4700 2x10. 4 bolt 110.
My ultimate goal is an odd ball 46/34 with 165 arms. I have a 4700 50/34 165 now. I can and have been using the existing 50 but a 46 would be a nice tweak and better for what I do.
The FC-CX50 crankset and swapping the inner to a 34 was not a viable option because the lack of 165.
