Roglič will not contest the time trial as he's still recovering from an elbow injury sustained in a crash at the Tour de France, where he finished fourth overall, but will lead the road squad on September 30.
"I haven't ridden my TT bike, so I can't really train to get a good result," Roglič said of his decision. "I'll only start when I can fight for a win, so I won't do it."
Bahrain-Merida's Matej Mohorič will also start the road race as one of the Slovenian team's protected riders, having won both the BinckBank Tour and the Deutschland Tour last month, and he and Roglič will be joined on the eight-man road-race squad by Mohorič's Bahrain-Merida teammates Grega Bole, Luka Pibernik and Domen Novak, Katusha-Alpecin's Simon Špilak, Jan Polanc (UAE Team Emirates) and CCC Sprandi Polkowice's Jan Tratnik, with Tratnik also riding the time trial.
"After such a good season, we can go to the Worlds with a really positive mindset, with our heads held high," Roglič said on the Slovenia Cycling website.

Cyclingnews is the world's leader in English-language coverage of professional cycling. Started in 1995 by University of Newcastle professor Bill Mitchell, the site was one of the first to provide breaking news and results over the internet in English. The site was purchased by Knapp Communications in 1999, and owner Gerard Knapp built it into the definitive voice of pro cycling. Since then, major publishing house Future PLC has owned the site and expanded it to include top features, news, results, photos and tech reporting. The site continues to be the most comprehensive and authoritative English voice in professional cycling.
