The story behind the name

The 1931 Giro d'Italia was the 19th edition of the Giro d'Italia, a cycling race organized and sponsored by the newspaper La Gazzetta dello Sport. The race began on May 10th in Milan with a stage that stretched 206 km (128 mi) to Mantua, finishing back in Milan on May 31st after a 263 km (163 mi) stage and a total distance covered of 3,012 km (1,872 mi). The race was won by the Francesco Camusso of the Gloria team. Second and third respectively were the Italian riders Luigi Giacobbe and Luigi Marchisio.

Of the 109 riders that began the Giro d'Italia on May 10th, 65 of them made it to the finish in Milan on May 31st. Riders were allowed to ride on their own or as a member of a team.

On the 6th stage the organizing committee decided that grouped riders will leave first and the isolated riders will leave 15 minutes later. Ettore Mein, who has a record of winning 5 stages of the Giro d'Italia, and one stage in the 1934 Tour de France was an isolated rider and closed the 15 minute time gap to win the 256 km (159mi) stage from Naples to Rome. 1931 also introduced the Maglia Rosa which was being worn by race leader Alfredo Binda but during stage 6, due to a crashing near the the Villa Glori hippodrome, Binda was was forced to relinquish the jersey to Michele Mara who then lost the jersey to Luigi Marchisio in next stage.

The Naro 1931 bib shorts are dedicated to the riders on who faced the challenges of stage 6 of the 1931 Giro d'Italia.
