That was down the most mountainous stage, non? I remember the commentators saying that they were doing about 80kph and couldn't pedal any faster.. unless they had shorter gearing for the grueling climb beforehand...Bodin said:
I don't know whether to believe 100kph on a roadie, but that's amazing!

No, I was referring to the first week when they were traversing across France into Germany on flat stages with a massive tailwind the whole way and were still averaging below 60kph.
I was actually being quite polite in my previous post, but to be honest now, I don't believe any group of cyclists in the world could average 85kph on the flats for 10 kilometres, regardless of how strong the tailwind was.
Most people struggle to hit 85kph down a hill, so I'm prepared to be proven wrong, but I don't think I'm unjustified in being a Doubting Thomas on this claim.

I remember in yr 8 when I was working for a chemist making deliveries hitting 67km/h with a big tailwind, never really got over 60 after that day, and overtaking a schoolbus on the inside lane. I didnt wipe the max speed on my speedo for a long time after that.
Lately on a mates road bike i got 75ish down a rough country road and about 500m from my house i regularly hit 55km/h down a dirt trail, which I reckon is damn fast let alone these guys hitting 80+.

Braking distance...
Now here's an idea..
While this might simply be a product of my top speed 'achievement' being only 67ks (down Cootha on the road), how many of you have seen how quickly you can stop from a speed like this...
So why not try winding it up to v-max, then hitting the stoppers, chest on the seat, rear wheel just touching the ground...those dinner-platter disc brakes have gotta be good for something right?
P.S. for *extra-fun*, try it in the wet....

Be very careful doing that... the centre of mass of a bike/rider in a normal position is such that on dry asphalt you physically can't lock the front wheel before going over the bars. If you get that far over the back (yes I've tried) you most definitely can lock the front wheel, and front wheel lockage at high speed = crash, no two ways about it (unless you are EXTREMELY lucky).benxc said:Now here's an idea..

Surprisingly quickly actually. I was hitting 80ks down the last section of fire trail at Mt. Stanley and theres 90 degree turn onto singletrack right after you hit the max speed part of it. I was pulling up to make the corner no probs , actually braking later with each run. I'm guessing my speed around the corner to be around 15ks , so judging by that ,to come to a dead stop from 80 would take about 30 - 40 metres? Maybe less?benxc said:
That fire trail is awesome , its 2 - 3 metrs wide but littered with football sized rocks and only a singletrack width of clean line down it. At 80 , you can't hear anything for the wind noise and vision gets blurry , making it even harder to stay on the clean line. Friggin fun , but !

I'v hit 90 km an hour on a hardtail with 80 - 100 mm of front travel down a dirt road/fire road. It was crazy, your eyes stream and all you can do is hold on and hope to god you don't slide out.

85kph down bayview heights hill in Cairns on my patriot. I just got new brake pads so I had to bed them in. The guy following me in his ute said he got to 85kph and had to back off...So what speed I really hit was a mystery. Towards the bottom of the hill they have these speed bump things, about 4m long with an up and down ramp...hard to explain. But i was hitting those at 80kph and airing massive.
