I find it amusing when people bash on the 4130's not lasting long, I've had my BB transferred from 3 frameset now (close to 25k miles) in order to run a bb30 quarq on bb86 frames.
True BB30 is "4230" so you are "loosing" 1mm total, 0.5mm per each side...
Also running 4130's on my mtb and it's been solid. The only pro of 24mm spindles is that they should fit every frame
