I rented a bike with a 34 front/34 rear combo in San Francisco. That combo came in handy with those hills. It was a 105 11sp setup but since it was a rental I didn't pay attention to the derailleur, all I know is it worked well as the bike was a practically new Spec Roubaix. As others are saying you can't really put a 34 on a 52, that's just too big a shift, but why would you not want to go 50/34 in front? Combined with an 11t rear that is plenty high. Honestly, I never get why people think they need such high gearing but fully understand the low gearing. And in reviewing this thread I didn't see it stated that you need the high gear anyway, just that sticking a 34 in place of the 36 is the cheapest option. It will never be as cheap or easy as you want it to be unfortunately.
