Gearing choice. I don't run into any shifting problems with either chainring (34 or 36). For the type of terrain we have here in Austin I find the 50/36 11/23 set up to work the best for me. FWIW I made the decision to go to a compact after doing a test with my coach and we determined that I make my best and most efficient power between 90-105 rpm. Below or above those numbers I get less efficient and make less power.
