About Castelli
At the front since 1876.
Castelli has been at the front of cycling apparel since 1876, founded in Milan as the original maker of pro race kit. From the first cycling jerseys to today's WorldTour-proven aero garments, the brand has spent nearly 150 years putting innovation onto the backs of the fastest riders in the world.
Castelli outfitted the first organised cycling teams in Italy and has been a constant presence in the pro peloton ever since. The Scorpion logo appears on more WorldTour podiums than almost any other apparel mark.
