I don't think I'd be losing much if anything at all, especially if I can crosschain fully, something pretty easily achievable with medium cages:
(this is for an all road bike...meaning gravel and **** too...)
You are comparing a 46 to a 52. That's not what we are talking about. You could easily go with a 50/34. The difference between a 50x11 and 52x11 at 90rpm is 1.3mph. I rounded down. To reach the same speed compared to the 52x11 @90rpm=33.2mph with the 50x11 is 94rpm. If you can't hold 4rpm faster then that's your own issue. Then you could run an 11-28, get almost the same low gear, and gain back 1 extra cog in the middle.
