Montauban - British sprint king Mark Cavendish believes Africa will have a Tour de France contender within 10 years.
Grand Tour champions such as Briton Chris Froome, Spain's Alberto Contador and Nairo Quintana of Colombia need strong cardiovascular and endurance capabilities.
These are areas in which east Africans in particular excel in athletics, with Kenyans and Ethiopians dominating from 1500-metres up to the marathon.
With lean physiques and the opportunity to train at altitude, and gain the pulmonary benefits that brings, African riders should be competitive in cycling.
And Cavendish, who rides for African team Dimension Data and who subsequently won his third stage race at the Tour de France, believes it's only a matter of time before they are.
"Within 10 years there can be a great rider for the continent of Africa," he said.
"I won't tell you who, but I think in this team we have the first big rider of black origin in cycling."
Two Eritreans are on the Dimension Data Tour team this year, Daniel Teklehaimanot, 27, and Natnael Berhane, 25.
Both are accomplished climbers, one of the essential components of a Tour champion.
Last year another Eritrean, Merhawi Kudus, 22, also rode the Tour while in May he finished 37th at the Giro d'Italia.
"It's not through a lack of talent that there hasn't been a standout rider yet," added Cavendish.
"Daniel wore the polkadot (climbers) jersey for a few days last year. That was massive for the team, for the continent and for the Qhubeka charity.
"For a black African rider to be a contender, it's not about talent, it's a cultural history thing.
"You have to start somewhere - that's with the guys who are professionals now, then it can filter down to the younger generation.
"We have a feeder team at Dimension Data and the talent is coming through.
"It's incredible, if we can ingrain a cycling lifestyle - something that's not taught but is instinct - into guys, I truly believe in the next 10 years we'll be seeing the continent of Africa being the next dominant force in cycling."
Teklehaimanot won the king of the mountains jersey at the prestigious Criterium du Dauphine both this year and last, and held the polkadot jersey for four days at the 2015 Tour, where he finished 49th.
Kudus was ninth at the Tour of Oman earlier this year and has ridden all three Grand Tours despite being only 22.
Berhane won the Tour of Turkey in 2013 and was fifth in the Tour of Austria earlier this year.
He's completed the Vuelta a Espana twice and is riding his first Tour.
Briton Froome was born in Kenya and grew up in South Africa, benefitting from altitude training from a young age.
He has since won the Tour de France twice and is the favourite to triumph again this year.
