>>1580773>not just slapping bullhorns onto the forkI reckon top tube could be in the way of properly tucking in, if the horns are sufficiently low, but you could just cut it off and maybe move the saddle closer to the bb.
Come to think about it, you'd need to move the bb itself backwards so maybe dump it entirely and just attach pedals directly to the hub (igh?).
Fast math says it could potentially give about 70-85% more gains on the aero only and with the right gear ratio and pedalling whilst pushing against the frame it should be possible to double that.
