Thinking of switching from a compact 50/34 crank to a 52/36. Ran the calculators at Sheldon's site and I am(and I guess always will be) confounded by gear inches and gain ratios.
The set up is front as above and 10 speed 12/27 rear cassette. I am most concerned that I will have the gearing to get up W. PA hills with a 36 front small ring.
So 34 front and 27 rear is a gear inch of 33.1 and gain ratio of 2.5
36 front and 27 rear is a gear inch of 35.0 and gain ratio of 2.6
At 80 rpm the bigger ring calculation is 8.3 mph and the smaller one is 7.9 mph. All this does not seem like much difference. Is there any real practical difference between the options?
