The hardest stage of the Vuelta thus far. The mountains were back after the sprints of Stage 8. The Alto de Velefique climb would be the last one which was 13.4km, before that three other minor ones.Damiano Caruso of Bahrain Victorius attacked the final 70km of the race to win solo ahead of Primoz Roglic who made sure to finish ahead of his GC contender Enric Mas to consolidate first his GC lead. Safety is now priority for the Vuelta organizers at long last. Check out the bloke in the reflectors signaling for the riders to slow down with 32KM TO GO on the dangerous sharp curve. The heat was an unbearably humid 30 degrees Celsius. I reckon it had a part to play the the chain being blown as you can see in the clip. Hot conditions affect the lubrication on it, the lubricants become what is called viscous(watery) so they seize to become effective to limit the friction as you paddle.
