According to Velon data Tiberi was riding 610w for 69 seconds during that first del Toro attack. Thats almost 10w/kg for Tiberi, so quite impressive.Yeah, it was not a high peak, but a 60s attack. If he did that intentionally, it was smart. He needed to cook Tiberi. If he gaps him immediately, they just do a 1 vs 1 TT in which case the final gap might not have been big enough.
