Reigning Tour de France champion Chris Froome is wary about how often he might make public his cycling physiological data.
Responding to constant speculation and slurs, the two-time Tour winner took the unusual step late last year of submitting to a battery of tests and letting Esquire magazine publish them.
While the consensus is that cycling has made progress since the Lance Armstrong scandal, no-one believes the doping-plagued sport is clean.
Froome insists he does not dope.
But fans constantly abused him during last year's Tour, with one throwing urine in his face.

Froome also notes the more information he reveals about himself, the more his rivals learn.
"The thing is, at the same time you have to remember, the more data you release, the more of an edge you're going to give to your competitors - the more you're going to give away about yourself, your physical capabilities," he said on Tuesday.
"At the end of the day, my job is to race a bike as competitively as I can.
"With that in mind, I'm not saying I'm not going to release any more but as the need comes I will look at each case."
Regardless, Froome is pleased with how the Esquire exercise turned out.
"People are asking for my data and I have nothing to hide, obviously," he said.
"I went and did the tests and offered that data up publicly.
"Not to say every athlete should do the same thing ... it's everyone's personal prerogative.
"I'd like to think people can see that I have nothing to hide, that I have just been open with my data."
