I'm not a Luddite; I recognise the benefit of the big BB axle, and I recognise the benefit of increasing the shell diameter to fit this big axle's bearings inside the shell, as well as the corollary benefit to frame structure of the bigger BB shell. BB30 is a good thing. I'm simply pointing out that BB386 is a retrograde step which is being introduced for logistical convenience, not improved performance.
Yes, you can maintain a sensible Q-factor with BB386, but if you do, the 'freeboard' between the Q and the outside of the bearing is 9mm less with BB386 than BB30. This is the space into which you have to squeeze both your medial malleolus and the thickness of the crank, all in a gap which is just 39mm wide with BB30. Cutting that by a quarter just to reduce inventory seems like one of the more idiotic ideas presented as 'progress'.
