Tour de France leader Chris Froome is uncertain if Team Sky disclosing performance data from his much-discussed win at La Pierre-Saint-Martin will convince everyone of the legitimacy of his performances.

The 30-year-old Team Sky leader has an advantage of three minutes and 10 seconds from Movistar rider Nairo Quintana with five stages remaining, four of them in the Alps where the yellow jersey will be won. The race finishes in Paris on Sunday.

The 2013 champion has been subjected to innuendo and interrogations over his dominant win in the first Pyrenees stage last Tuesday, with host broadcaster France 2 among those to seek expert analysis, but he insists he races clean.

The clamour for Froome's actual figures led to Team Sky principal Sir Dave Brailsford inviting head of performance Tim Kerrison to reveal the real numbers behind the display on the race's second rest day.

Froome said: "I'm not sure if numbers are going to fix everything, but certainly I feel as a team and myself, we're definitely trying to be as open and transparent as possible.

"We've been asked more questions than any other team. I've been asked more questions than any other GC (general classification) contender. I'd like to think we're answering those questions.

"I really am focused on the racing side of things. I've worked too long to let anything throw me off. That's all just happening on the side."

Brailsford insisted performance data would not be released every time Froome beat the field and expects the furore not to detract from the Kenya-born Briton's desire to win the yellow jersey this week.

Brailsford added: "We're here to race and racing's a human endeavour. It's not a set of numbers on a spreadsheet, it's not a power meter. It's about racing.

"There's a human aspect to it. That's why we all love bike racing. And we're going to go out and try to win this bike race.

"I'm sure if Chris feels that he can attack and he could go and leave everybody behind, it would be a travesty, I think, if he had any doubt in his mind thinking 'oh, I better not'. And he know he won't.

"That's what we should do: continue to race in a clean and pure fashion."
