In 2014, Štybar won the World Cyclo-cross championships for a third time in an intense battle with defending world champion Sven Nys.
In trying to defend his title in the 2014 Eneco Tour, Stybar crashed into the steel barriers in the fourth stage near the finish line and had to undergo hospitalization. He broke and lost his front upper teeth in the crash. Upon his return, he complained to the UCI that the same dangerous barriers were used in the Grand Prix Cycliste de Québec. His first victory upon his return was Binche–Chimay–Binche, where he attacked inside two kilometers to go on a small cobbled climb after being led out by his teammate Niki Terpstra at the foot of the rise. Štybar had time to celebrate, coming in 2 seconds before John Degenkolb and the charging sprinters.
