Anyone use Ratio Tech to run 1x13 on rim brakes

[jimcav]

I’m converting my Kirk from red10 to campy 11 but the current FD and crank ( SR but with TA spec. rings) is giving me fits trying to get good shifting at FD. That got me thinking about doing a 1x13 because I have a set of etap 11 shifters and the Ratio Tech is advertised to work with sram 11 shifters. It is probably too much of an outlay of $ to make it reasonable given that I have 11spd stuff on hand. My orig. goal was to have my modern bikes be 11 so I can easily move wheels around, but I wondered if anyone here had tried the conversion?
Thx
Jim
