Most Innovative Race Gear

Castelli T1 Stealth Top

What a swim skin is to the swim leg, the Castelli T1 Stealth Top is to the bike leg. This long sleeve top is designed to be worn over a tri kit while riding to reduce aerodynamic drag and block the sun, then taken off for the run. Covering the arms with certain fabrics can reduce wind drag and the textured material covering the shoulders and back is intended to help delay passing air from fluttering off the back of the rider, which would reduce resistance. Tri clothing makers such as Pearl Izumi and Castelli have developed suits specifically to keep cycling drag low, but this is the first additional piece of race gear created to be worn just during the bike. Castelli claims the T1 Stealth Top is worth substantial time savings compared to riding in a tri suit.
