I've got the same Chorus pre-2015 groupset as the OP. It has a short cage Chorus RD. Currently limited to running 28T cassette.
Am I right to think if I want to do this incrementally, instead of buying a new crankset ..
1. Install a Roadlink + chain length .. which should increase ability to handle up to 32T cassette
2. Install a Roadlink + modify to Medium cage + chain length .. which should increase it to support 36T ?
