Cyclocross and Gravelbiking (Recreational) This has to be the most physically intense sport ever invented. It's high speed bicycle racing on a short off road course or riding the off pavement rides on gravel like :The Dirty Kanza". We also have a dedicated Racing forum for the Cyclocross Hard Core Racers.

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.

When I looked into this back in January the only option I found was to use an Ultegra 46t ring, which is $115 dollars or so.

I just pulled the 4700 crankset, sold it for $50 and got a Shimano non-series RS500 46/36 with 5-bolt 110bcd for $72 from Merlin Cycles. Not sure if this is helpful

Pretty sure that ring is only for FSA cranks but that adapter is interesting, never seen that before.
