this is just mimicking modern TT position on a road bike (“praying mantis TT position”)
with this fast position, you minimize the gap between your arms and your head/chest, specially with a ridiculous helmet like this, you end up with virtually no gap.
so yes, if you create something like this on your roadbike, you might be faster in a solo breakaway. but your will probably take out half the peloton if you crash
