A developing climber joins Tom Pidcock at Pinarello
Castellón is not as much of a big name as Berwick, a former World Tour rider, but has been developing steadily in the ProTeam ranks. The 23-year old is a product of the Spanish team's development ranks, and last year finished in the Top10 of the Tour de Hongrie, Tour of Slovenia and La Route d'Occitanie in quick succession.
This year, his level has gone up a notch, with Castellón riding to 11th place at the Tour Auvergne-Rhône Alpes, which featured plenty Tour de France contenders. Despite this, he was not selected for the team's maiden Tour de France participation.
“What we particularly like is his racing instinct. He wants to attack, be involved and discover where his limits are. At 23, there is still plenty of room for development, and we believe our Team environment can give him the tools and support to take that next step".
“We are bringing together riders from different countries, backgrounds and cycling cultures, while giving each of them access to the innovation and individual performance development that define this Team. Jan fits that philosophy extremely well.”

Jan Castellon wants to become a serious GC contender
Castellon joins reigning national champion Marcel Camprubi as the second confirmed Spaniard in the team's ranks for the upcoming season, with the team now having eight confirmed signings. Castellón sits amongst big names such as Mauro Schmid, Tom Crabbe and Netcompany INEOS rider Andrew August.
“I feel this is the right moment to take another step in my career. Over the last two seasons I have seen that I can perform consistently in professional stage races and fight for general classifications," the Caja Rural rider added.
“I like to race aggressively. I want people to see a rider who attacks, who is always trying to win and who takes his opportunities. That mentality fits very well with Race Sharp".
Whilst the Swiss team remains in the sport's second division, a promotion is likely within the coming years as the team is performing above several World Tour-level teams. Besides, its constant performances allow it to have guaranteed wildcards for all races they so desire, and so opportunities will grow for the Spaniard, who wants to become a stronger contender for the overall classification battles.
“I want to keep developing as a GC rider, but also improve in one-day races. Looking further ahead, making my Grand Tour debut is another step I would really like to take.”
