Pedal strike is a problem if the rider panics when it happens. Pre-priming panic is a very bad idea.

The strike lasts what --0.01 second? We're talking about the bottom 2 degrees of crank rotation while the crank is moving at 100rpm. The bike does not have time to get off the ground. Neither is the bike a perfectly rigid system. And it is not like the crank buries itself a centimeter in the pavement, creating a new little pothole. All that happens is 1 millimeter of pedal scrapes for a moment.

The old test for low bottom bracket was to walk the bike around a bit and if the toeclips clattered on the ground a lot that was a nice low bike. The toeclip clatter is much worse with fixed gear. The flip side is low BB gets you through corners much faster. Yes, you must keep your inside pedal up, still that corner is way faster. The entire bike is more aero, just plain closer to the ground. Going from a high bike to a low bike the change in drafting is quite dramatic. Not only do you get a better draft off everyone, in a race situation you are denying draft to followers. No one will ever know any of this unless they ride old bikes. Real old bikes. Bikes with 9 and 10cm frame drop. Absolute conformity is the order of the day now and these bikes will not be built again. Even custom builders would be mostly unwilling. Absolute conformity enforced by errant nonsense and lots of screaming about non-existent danger danger is why I am old and grouchy.
