You may have seen some rumors out there, but now it's finally official and time to celebrate. Castelli will be outfitting the most successful WorldTour team, Quick-Step Alpha Vinyl, with our entire arsenal of racing and training clothing.

Castelli will bring its aerodynamics expertise for road races, time trials, and track racing. The TT specialists have already been fitted with custom suits and will be testing in the wind tunnel in January to refine the performance further. For Quick-Step Alpha Vinyl, the top sprinting team in the pro peloton, Castelli is creating a race suit specifically for the high speeds of mass sprints.

We have long admired the Quick-Step Alpha Vinyl Team's meticulous approach to pushing the technological limits of the equipment, the same approach we take with clothing. And as always, every innovative product created with Quick-Step Alpha Vinyl will eventually trickle down into the standard Castelli collection, and the Servizio Corse custom team wear program.
