Pirelli P Zero Race RS (Non-Tubeless) – Performance vs TLR?

GCN just did a video on it, promoting the benefits of the Non tubeless P Zero and TPU tubes. Only to finish saying that for the Fred Whitton he stayed tubeless, a p’ture would cost him a lot of time, the better rolling of tubeless would save him minutes whereas the lighter set up would only save him 12s.
