The descent of the Col de Crostis on the 14th stage on May 21 has never been previously used in the Giro and is partially unpaved. Riders are concerned that there are no crash barriers, just ski netting.
Race director Angelo Zomegnan told Gazzetta dello Sport on Wednesday: "I understand after Wouter Weylandt's death that riders are worried about the descent of the Crostis."
Zomegnan said officials would be sent to check the sector, and that "our priority is that riders can participate in total security."
Weylandt died Monday after he crashed during a descent on the fourth stage of the Giro.
