Saunier Duval-Prodir riders will carry a bit less weight over the big climbs than other teams, since their innovative Castelli Superleggera jerseys weigh a mere 70 grams (in size L), less than half the weight of a traditional cycling jersey when dry.

And a soaked Superleggera jersey (due to perspiration or rain) weighs only 140 grams, compared to 400 grams for a standard team jersey. Castelli claims that a Superleggera jersey would provide a one-minute advantage over the course of a five-hour mountain stage.

Keep an eye on those jerseys in coming weeks.
