How about BB30?

We do offer a pressfit BB30 shell but we always remind people that it takes away from the overall stiffness of the BB area of the frame. The cranks are a larger diameter, but you don’t increase the stiffness of the frame at all. Also, a threaded BB has more purchase and creates a wider platform for the cranks, not to mention gives you the option of changing systems if you would like to do so in a few years. Remember, the frame will last a lifetime, technology doesn’t. — Kent Eriksen, Kent Eriksen Cycles – FAQ’S
