Aero Road Jerseys - Who's In?
Looks like aero road jerseys are making a big showing at the TDF. Who's ready to look like a tri geek to save 12 watts at 40kph?
"Castelli claims that the new jersey is 12 watts faster than the old version at 40 kph; that’s 12 watts faster than a piece of kit that was already at the top of the aero game. How much can be gained over a traditional, flappy jersey? “In the range of 32 watts at 50 kph,” said Castelli brand manager Steven Smith."
