He's a clone of Almeida on the climbs, but more explosive.
He's very good, but with these characteristics, I see him more as a rider for tough classics and one-week races. For the Tour, I think Seixas will be a more dangerous contender in the future. And we'll see if Lipowitz.
Del Toro is an improved Ayuso; they both resemble Valverde. They're going to struggle to win a Tour and Giro against good climbers.
But they're going to win many races (they need to improve on Monument-distance races; Valverde was very good at that).
