Looks as if something failed on his time-trial bike, but what? His disc wheel?

I'm guessing a wind gust.

My money's on a bike failure of some sort.

Ouch

That will be a memorable 19th place finish. Sure looks like something failed to me.

Glad he seems to be okay considering.

I am leaning more towards equipment failure and less towards wind gust.
Though what the failure was I haven't figured out yet

upd: While on the course he sits on the nose of the saddle, but that's nothing unusual.

He lost grip on the sand. From the horse’s mouth.

Well, a small cloud of sand was kicked up when he slid on the pavement. But it's curious that he slipped on the finishing straight, and not in the previous corners, where he was leaning his bike pretty aggressively.

No way is that a slip on the sand, I say the free hub pawls broke. Pro's are unlikely to talk about equipment failures of continuing sponsors.

Gravity. It'll get you everytime.

Dont buy the sand either.
Thats not a bad guess. Looks plausible to me.

slipping would seem to show a gradual or sliding motion in the video.....but it looks like it was more of what I call a "snap-failure". Something seems like it snapped and as a result, his weight shifted dramatically. At first I thought it could've been his seatpost or something in the rear drivetrain but seatpost is still there when he hits the ground.

Per the post above, no team is going to dump on their sponsor over an equipment failure and I'm guessing Tiberi didn't hang out to inspect his own bike to know what caused it either.

First sign of trouble I can detect is the left foot/leg freewheeling, sudden drop from 12:00 to 6:00. Could also have been a broken rear derailleur, tension, causing the chain to skip on the cassette cog.

Michael Maddox · #13 02-23-2021, 04:38 PM

It does look like his leg shifted forward quickly which might be DUE to the slip or might have CAUSED the slip. Hard to tell.

LOTS of stuff bouncing down the road after he went down, but the bars seem intact. What WAS all that?

bicycletricycle · #14 02-23-2021, 05:05 PM

I think a loss of traction that caused the wheel to step out and then suddenly re grip makes sense. I guess sand plus wind plus some weight transfer to the front could do that?

veloduffer · #15 02-23-2021, 05:17 PM

If I recall, sand in the Middle East is very smooth and can be slippery (think of the dust on the Paris Roubaix cobbles). For construction in the Middle East, sand is imported because the local sand isn’t granular and rough enough.

So it could have been a combination of sand and wind for the rider to lose control.
