Aren't allowed by whom? They're certainly legal for USCF racing, and there are enough pictures on cyclingnews with them to make me believe they're legal for UCI.
It is obvious you arent a triathlete.
As far as the helmet goes, yes, it does make a bigger difference than the wheels. Repeating a fact doesn't make the fact true, but merely publicizes it. So thanks for finding one instance of a study..please talk to some triathletes and see what they say.
USAT governs most races of consequence and here is a quote from their rulebook "(g) Except as otherwise determined by the race director in the interest of safety, the front wheel may be of a
different diameter than the rear wheel, but the front wheel must be of spoke construction. The rear wheel may be either spoke or solid construction. Wheel covers shall only be permitted on the rear wheel."
So no... you can not use a disk on the rear. Next time, please know what you are talking about before you are so quick to criticize.
