Froome, who is targeting a record-equalling fifth Tour title, and defending champion Thomas will take to the start line in Brussels on July 6. Bernal, who enjoyed a revelatory first season at WorldTour level, will lead the team at the Giro, starting in Bologna on May 11.
Explaining his decision to target the Tour, Froome said: "It’s been a hard decision to figure out exactly what to do in 2019 and figure out which Grand Tours to focus on, especially having won the Giro last year and having had such an amazing time out there with the team – but for 2019, my number one objective is going to be the Tour de France.
"It was definitely a difficult decision not to go back to the Giro d’Italia and defend the maglia rosa. I’ve got some amazing memories from last year, but I think, with the Tour de France as my main objective, it’s probably better that I skip the Giro d’Italia in 2019.
"I’m getting to the point in my career now where I’m starting to think about what kind of legacy I want to leave behind and if I am able to win the Tour de France for a fifth time and join that very elite group of bike riders - only four other people have ever done that - it would just be incredible."
