/ What's the steepest gradient for a road bike?
In light of the recent race:
Both these things tend to start happening at around 25-30%. If there was more friction from a thicker back tyre or a really grippy road you could stand up, lean forward and then the limiting factor would be your gears and leg power.
I would imagine my limits are around 25% on a fairly slick wet road, with normal winter tyres on a road bike. 30-35% sustained in good conditions with normal tyres. I don't have a clue about if I was to change the gearing and stick on a mountain bike tyre on the back - short sections of 50% perhaps?
It would be pretty tough to find out though because you would have to first build a new road or ramp to test it. Steepest at the moment is thought to be Baldwin Street at 35%.
He ignores at the end how the amount of weight and therefore friction, going through the back wheel changes as the riders weight goes forward. From my experience this is the limiting factor so fairly useless piece of work! Still, an interesting read.
No chance 80%.. even in the dry..
But there were riders pushing their bikes at 27% in the Tirreno-Adriatic?

Bicycle geometry as opposed to theoretical power levels would be more relevant on really steep inclines. It would probably be possible to design a bike where your weight distribution and position would be such that it'd be easier to cycle up steeper inclines. Though it would probably be very inefficient elsewhere and a dog to cycle on longer flat sections. Or in simple terms power means nothing without having the ability to transmit it.
Steepest in the two 100 climbs book :]
Or going down................?

I reckon it was about VS
