Chris Froome; Doping?

<< < (3/6) > >>

Narcoleptic Insomniac:
Then they should have a doped category and non-doped category. I'd watch that.

amishrob:
there's a very vocal twitter 'group' who are accusing everyone, based on very loose 'facts'. they were posting round a picture of valverde using an inhaler before an attack the other day. it's naive to think sky aren't using some grey areas though. i met the team yesterday (walked past, didn't want anyone to talk to me as i'm forced to wear team sky t-shirts) and they seem like nice guys mostly.

MilkyWilky:
Very obvious chem-trails above the tour. Everyone's doped.

Allah:
Nice to see some intelligent threads on BG over the last few weeks.

Hey G, excuse my ignorance but what are elliptical rings? Oval chainrings? What advantages do these offer and if there is a significant difference why don't we use them in everyday cycling (or BMX for that matter)?

Kinchy:
They supposedly utilise power at different points of the pedal stroke, so when you put out more power on the down stroke the chainring provides a slightly different gear ratio to what it would when your foot comes across the top. Different oval chainrings work in different ways, so some make the most of the down stroke power, and some even the output out over the whole stroke.

Or something like that.
