2018 Tour de France hero Thomas and four-time winner Froome set for break after gruelling season.
Tour de France winners Geraint Thomas and Chris Froome will sit out the Road World Championships in Innsbruck later this month to rest and recuperate.
The British duo skipped the Vuelta a Espana in favour of the Tour of Britain where they are currently competing.
"Froome and G [Thomas] will finish their seasons here. It's good to finish, on not necessarily a form-wise high, but on a morale and psychological boost for next year on a high," Team Sky sports director Brett Lancaster told Cycling Weekly.
Two-time Olympic team pursuit champion Thomas and double time trial bronze medallist Froome were part of the provisional British selection for the road race and individual time trial.
Froome won the Giro d'Italia to complete a full set of Grand Tours in May before Sky team-mate Thomas took Le Tour in July.
In their absence, Alex Dowsett and Tao Geoghegan Hart will probably fill the two spots for Great Britain.
“I think G originally thought about it [riding the worlds], I would have wanted him there in the team time trial but obviously he is burnt out after a massive season and the stress they put themselves under with training and diet etc,” Lancaster continued.
Rio 2016 silver medallist Tom Dumoulin is the favourite to retain his time trial crown.
The Road World Championships in Austria will take place from 23 to 30 September.
