Italian cycling clothing manufacturer Castelli has struck a deal with Amaury Sport Organisation (ASO), the body behind the iconic Tour de France (TDF) and a host of other prestigious road cycling events.

Through the tie-up, Castelli becomes the technical clothing partner of all races and challenges organized by ASO through the 2027 European cycling season.

The agreement entails Castelli producing and designing all classification jerseys worn during events such as the TDF and Tour de France Femmes.

Castelli has produced these jerseys for the TDF before, specifically, between 1989 and 1994.

In total, 27 races organized by the ASO are included in this agreement. Castelli has also had a similar tie-up with the Giro d'Italia over the last decade.

The 2027 Tour de France will begin in the UK on July 2 and end in Paris on July 25.
