Anyone here running old Di2 FD with new GRX RD combo? I have the pre-Ultegra shit on the Kinesis and it runs 34x42T without Wolftooth but to get lower gearing without changing the cranks I reckon I'd need a WT or maybe look at replacing the stuff with GRX bits. No idea if adding a WT to the mix would allow me to run a 46T MTB cassette though. Thoughts?
