The travesties that the bike industry has unloaded on us are ongoing. BB's are a case in point. In their initial mindset of advancement was to change the interface design to a spline like cassettes. Seems reasonable, but wait, the BB axial has far more non-axial stress than a cassette, so the BB interface had better mesh well. However, that didn’t do much for weight reduction and was no better than square tapers, so was cast aside (octa-stuff). Next, let’s try a large open tube in place of the solid BB axle. Great, but now the bearing won’t fit. Let’s “try” putting the bearing external like the headset. And, headsets are now press fit, so let “try” that with BB’s. Oops, so surprised, BB’s have far more non-axial stress than headsets, so with small bearings the BB’s have short life or the BB is not rigidly held to the bike, so it creaks and wears. More space in needed and so another new standard is born ****T47****Haaa Raaa. Maybe they have finally made an advancement. I’m fine with square taper until the dust settles.
