Completely unscientific question...
I have a 42 front 10-42 rear setup on my gravel bike... for the last couple years I'm trying to convince myself to pull the trigger on a road bike with 52/36 front 11-30 rear setup.
For a recreational and never will be competitive rider, is there any reason to let this stupid thought win out?
It would certainly give me more top-end but would the gearing be any easier/more efficient to pedal? I have absolutely no mathematic principles to apply to it but I just feel like having more teeth up front (52 vs 42) would be more efficient since that force is pretty direct compared to having less in the back (11 vs 10) which takes more indirect force to spin.
To answer the obvious--no I will not change my gravel bike gearing and no I won't want to sell it to switch over--I'd want to keep both bikes. It actually came stock with a 50/34 11/36 setup but there's something in my head that wanted to stick with a simple single ring setup.
There's also something in my head that really wants to go with a di2 setup and is trying to win over the other half of my brain that reasonably doesn't want to drop 4 grand to get me there to do essentially the same type of riding anyway (I primarily use my gravel bike as a road bike).
