This is a FIRST! I've never seen this before!

TWO discs at the Italian National TT Championships!!

Not so much - Cioni and others used 2 disks in the Prologue for the Giro.

More interesting was the stuff on the front wheels of the Saunier-Duval bikes…

Anyone know what’s going on here?

If it is still that will work, I have one that I haven’t used in about 10 years if you would like to try it. We always have wind in Hawaii so it is moot. Occasionally you will see one at a TT event. Pretty scary driving in a crosswind.

Looks like they need to be re-indexed.

(cool!)

No way I could get a day without wind on the east coast of Florida. There’s always wind here!

Some hack by the name of Moser used dual discs 20-something years ago…

OH…should have been more careful…I’ve always known about front dics, but I’ve never seen them at any of the major races. They are pretty damn hairy in a wind.

My guess would be it is a way to increase the surface area 1) cheaply AND/OR 2) without greatly increasing the torgue the wheel subjected to in cross winds (since a deeper section wheel has more of the surface area away from the pivot point).

It would seem that it would not be as beneficial as a deep section wheel, since the purpose of the deep section is to delay separation off the leading edge, but it certainly seems like it should help at least a little in a cross wind and is also gotta be cheap. Kinda like a 1/4-CH-aerocover …

TDF 1989…2 discs…but definitely missing the aerobars :wink:

What about Steve Hegg?? He used a double-disc at the 96’ olympics(road ITT)…

Hey, he matches the fountain.
Ugly.

It was the saddlesores, man…the SADDLESORES!!! NOT those silly contraptions that yank had on his bike.

I’m a little more concerned about the attire of this spectator…

Discs front and rear where popular before the UCI banned the use of different size wheels between the front and back. If the course is oriented such that quartering tailwinds were the norm, the dual discs would probably help quite a bit but if the winds shifted, ooh boy. I had a competitor take a nasty spill in front of me during an ITT in a stage race back in 87 or 88. The course was point to point and for the most part lined by trees and we were sort of enjoying a quartering tailwind and were moving along easily about 29-30 mph with him 45-seconds up the road when he passed by a large break in the treeline and immediately got tossed like a rag doll by the sudden side loads from the wind gust! My bike, a Tomasinni with a 700c disc in back and a 26" radial up front was a little less of a problem but when I hit the gap in the trees, I thought a large semi tractor/trailer had passed as I instantly swerved 5-6 feet. I can’t remember who it was elected to gamble on the use of dual disc wheels in the Tour a couple years ago - want to say it was either Rumsas (before his suspension) or Botero - regardless the rider had to switch bikes because the winds/gusts were defeating any performance adavantage offered by the discs.

On weight weenies they’re saying it’s a solar panel for their magnetic, frictionless bearings.

French women tend to dress provocatively.

dude…thats just wrong putting that here. We don’t need to be subject to that fashion horror again.

Yup, also note the aerohelmet and the natural arrangement of the vortex generators… begs the thought, should we leave a 5-8 mm strip of stubble about a third the way back on our shins to function as a vortex generator?
