Description

The Castelli BTW speedsuit short sleeve 2024 is a road speed suit that offers all the aero performance of a TT suit with the comfort, functionality, and moisture management needed for the road.

More than ten years of development on the roads of the WorldTour and in the wind tunnel.

Like every Castelli speed suit, the San Remo BTW opens completely along the front. This is useful for ventilation but also makes it easy to take bathroom breaks.

It also has three full-size rear pockets for storage and uses the Progetto X2 Air chamois. For extra aerodynamic benefits, you can combine this suit with the Bolero SS base layer.

Please note: keep in mind that Castelli clothing runs smaller than normal.
