As someone suggested on the uci webpage are the speedtrap results next to times. Just look it up. Usualy the top speeds are 60-70kphYeah but how fast do riders go in world cups???? As per the OP
I hope you were under the influence dave- as you seem to have agreed with everything I wrote. Zee beer goggles are thick, no?bla bla blabaddy. bla bla... the broken record skips again
in the 90's DH racing was down wide open fire roads... go look at the footage floating around youtube from MSA, Kaprun, Mammoth, etc
and if everyone os wearing the same thing there is no advantage/disadvantage
most of the races this year were decided by large margins... 2 or more seconds between each place. and if you look at the speed trap times the winner of the race more often than not was not even the fastest, and at times a few k behind (that few k of speed you are arguing they would have made up wearing something else)... there goes that theory
the few races were time were super tight (labresse, Bromont, Andorra) aero-dynamics would not make a difference.
when the average speeds are only in the mid to low 20's (most wc's) than pedaling power will gain you more than wearing one outfit over another.
nothing to see mickey... move on
So, if he was going up the hill at say, 40kph, then how can that possibly be an accurate reading.
They have started running those here in socal as well. Not sure if Sanbernardino caounty has any yet, but I have seen at least three of them in riverside county now. From my understanding, its a computerized system. There is a radar at each corner of the vehicle placed at an appropriate angle to measure speed. It uses the vehicles own curent speed Via an average of all four wheels through the ABS system, compares it to at least two of the radar readings, and gives a display. So if you pass him up while he is sitting still, a front and rear radar reading will give the speed of the vehicle passing, if he is driving and you pass, it will calculate the speed by comparision, same if your going the other way.Aussie cop cars have radars mounted on them that are designed to work when mobile. I'm not sure what they calibrate them from, be it the wheels or a second radar pointed at the ground or something, but they're accurate enough to be considered legally binding evidence in court. It's not a guy sitting in the drivers seat holding a radar gun out the window.
I got pulled over with moving radar 8 years ago here in Vermont, it's been around a while.They have started running those here in socal as well.

From what I get its extremly accurate, far more accurate than an officer holding a radar stationary due to all the calculation the computer that is controlling it is doing<current speed, angle of read, comparision between radars, alot more that was listed off when I asked about it>
Really is a pretty cool setup
Looks like we agree, then. I would think the limiting factor is finding a section that's sufficiently long, straight, and smooth, rather than any combination of aerodynamics and rolling resistance, since it takes a long time to reach terminal velocity and steep trails aren't in short supply. In any case, this certainly wouldn't be a typical DH trail, as you said.I said that it'd be hard on regular tracks not enywhere. 6-7 years ago we had a dh cup even at one place that mid track had a ~1km long fireroad and people were going 90+. I just suggested that unless you ride on a pretty unusual track it is highly unlikely because of the rolling resistance etc. Also you may run much higher pressure than most people. It helps greatly.
BTW. crazy high speeds seemed much less sketch on old my old brick that weighted a ton and had a wheelbase of a truck. On my newer bike I'd be probably much more scared.
Yeah, I Was just stating that on dh tires with normal pressures (I run 15-20psi in front) getting to that speed will be much harder than we think. When I was younger and into xc and ocasional road going with crazy speed down smooth roads was easier.Looks like we agree, then.

P.T.W,
The OP's question was answered long ago, which is why we've moved on to assorted ramblings and squabblings.
there is nowhere to hit 50 at MSA... the speed trap is on the fastest part of the track and the speeds were not even close to that.The winning pace at MSA last year was 31 mph, and it was slow in the upper woods in the mud, so I think it's pretty safe to say almost everyone in that race hit 50 at some point.
Not really. Sam's winning run was 23 seconds faster than that. The 3:10 Dan puts down in the vid would have put him around 110th in the semi, not even good enough for the finals.here is a good vid

damn 52 mph on a DH course? i have a hard enough time hitting 45 on my road bike with 53t-12t.
but the max avg. is about 40mph which is about 64km.
its funny sometimes you feel like your doing 40-50 mph but your really only doing about half that!
but dont forget this is the internet. the last DH race i did my avg. was about 77.356km. so i mean my top out must have been near 100km. but im just guessing.
When I pulled out to pass big-ted going down there, I pulled out into a bit which was much rockier than the rest. At about 45mph I got an instant flat. Was a bit of a sketchy moment to say the least, and had me walking/bussing back to Morzine to build a new wheel. Fun daysOn that same fire road from Lindarets to Chatel me and my mates did a slip-streaming affair like the roadies do, and when i pulled out to pass I got my computer up to 52mph. Even with full Dainese, a mx helmet and goggles i was ****ting it!
Yeah that's the one I think.Is that the one that cuts through the bottom section of the French National?
Only place of I can think there is where it comes out and straightlines down to the Mossettes lift.
The one from the Chatel bike park back into the Linderettes valley is pretty hairy, lots of walkers on that normally & a flat hairpin halfway down after a long flat out section. The drainage ditches are pretty lethal on that too.
Anyone tried the one that takes you from Avoriaz (through the hotel complex) down into the valley ending by the Morzine/Avoriaz telecabin? Thats possibly the scariest one of the lot, steep and loose as hell with loads of off camber corners.
The fastest I've gone was 57 according to my computer...... was on the Ribbon trail in Grand Junction, Colorado.What's everyone's fastest speed they have gone off road on a mountain bike?
