The peloton just happened to be riding fast comme par magie eh.

I already said it was also the DS's fault as well for the usual 'tactic' of teams wanting to be at the front for the descent.

So it's a combination of factors. The interest sprint teams had in the stage was also one of them.

On the descent where the crash ocurred, they were riding in clumps of two or three riders on a non-technical descent. If they were pushing the descent they would be in single file. Anyway, lets hope stage six is dry.

You’re not really suggesting that? DS’s are not different from coaches/managers in many other sports who feel the need to inject themselves into the action to justify their existence. Give them an opportunity to assume more control—or in this case handed a giant loudspeaker that is the race radio—they will take it.
Patrick likes to run in front of the parade, too.

I will make some popcorn for anything definitive about which brake types are better for raining or after rain conditions!!
Used both and I have not ridden medium to high end Campy or Sram in rainy or really wet conditions but I can say from my personal dats set that Ultegra and DuraAce rim and disc brakes have worked flawless in zero visibility raining and riding w tons of standing water on the ground!!
Having raced in heinous conditions with both of those rim brakes I would agree it lessens the panic effect that locks wheels. After that; if you don't have brake pads/rims that respond and tires that don't hydroplane it doesn't really matter.
It also doesn't matter what you're riding when a wall of bike parts are in your grill. Yer headin' fer the ditch, Cowpoke!

some strange comments on here re aquaplaning and bike handling.

aquaplaning is when the width of a tyre forces a wall of water in front of it. if the treads cannot shed this water (F1 tyres have specific litre/mi or eq rating), then the tyre/wheel starts to ride up over this wave / wall. the tyre lifts, you lose traction and all bets are off. i have done it on a car and a motorbike. on a car its a strange lifting floating feeling, on a motorbike its bloody terrifying. the onlly thing to do is pray.

The likelihood of aquaplaning is a function of speed, water, tyre width, contact shape, tyre shape, vehicle weight etc. for any given set of badly wet conditions then speed and tyre width are critical. bicycles have very narrow tyres and therefore it is exceptionally unikely for a bicycle to aquaplane.

in F1 and motogp, and indeed for anyone trying to go fast on the road, yes, you do the majority of braking and accelerating in a straight line, but you still brake up to the apex, and then start to apply the throttle immediately after the apex, so on a bike, you are cranked over both braking and accelerating - both in the dry and in the wet - just very carefully. in fact, at the top of motocycling, you have to chuck the bike over whilst hard on the brakes since the forks are still compressed giving you a steeper steering head angle and faster steering.

to me it looked like fresh tarmac with some standing water and raised white lines. fresh tarmac can still exude some chemicals and at the scale of a bicycle tyre a raised white line raises signficant changes in camber and grip such that crashes are really hard to avoid.
 
would be interesting to know what this is about :D

Look at the spectators video of the crash. The speed of the riders was very high (the riders themselfes spoke about 60/70 km/hour. Definitely the speed of the riders in that downhill was way to high taking into account the rain that only fell on dry smooth asphalt (with dust, oil....). One rider using his brakes, even straight ahead, can cause a crash and a domino-effect. Other riders gonna use their brakes in a reflex. An announced disaster.
 
CdD Facebook website has the signing in from 11.35 CET so I'm watching to see the state of the poor guys from yesterday. I'm guessing the local chemists had a run on bandaids and gauze.
No news is good news they say (whoever they is) so far only the 2 Visma DNF's & Menten from yesterday not starting today.
 
Yes and faster, I was outside of Tucson in an out and back ride going up Mt Lemon sky opened up. Been on Mt .Palomar and on Banner Grade in similar conditions, big difference was I didn't need to get a wheel. If you get gapped in a pro race,rain or no rain, get crushed in a cross wind and you lose contact your day is over, maybe your race if you miss the time cut.
Me riding around with friends and giving each other distance and a huge difference.. Designated regrouping points.... In bike racing it's opposite, if someone loses contact with you they don't want to see you again, that the goal. So bike is the same, speeds, conditions are the same, difference is drafting, tailgating in the rain on purpose as a point of survival. Nothing Remco or Roglic can be taken seriously, because both riders are never scared, never go to a race, sun,rain, whatever, they are never thinking that they are getting dropped. Lots of these guys are holding on for dear life.
I have zero idea how a race or the UCI could come up with some safe following distance rules when conditions turn to schit. I know for sure that if I am some water carrying grunt and it's pouring, I am keeping the wheel in front of me and willing to follow a little close to make it, make next selection.
I consider myself a below average bike handler and my main point is equipment has little or nothing to do with these situations, surprised not to hear some tin foil talking about hookless rims before people hit the pavement, people were still midair as disc brakes were the cause!!
I'm specifically talking about the guys in the back that crashed when they were trying to brake. They had a gap to the rider infront of them and they still fell.

At that speed, with thin tyres and combined with an unnecessarily strong braking-force (disc) on wet surface the chances for a slip & slide are good.
