Some Sky riders. Froome, Thomas, maybe Kyrianka (can’t spell that). Most are just using the regular bars, but ya they are impressive! I like how they flatten the backs to fit tightly against the forearms.
So many people obsess about a couple of inches of exposed brake or shift cable and then have even more round aerobar tubing hanging out in the wind.
that is interesting how the flattened the top of those extensions.
do you really think the round extensions pressed closely to a rider’s forearms are creating more drag than the Sky bars above?
Thomas uses pretty flat bars, but if you look at the edges they look contoured. My round bar comment is mostly about all the people running J bends and holding the tops.
just easier to print and lighter.

Those are gorgeous.
No hardware. I wish I could buy a set.
I wonder if anyone has studied how the pads interface with forearms in the tunnel.

You could totally buy a set. You just wouldn’t want to pay the price.
I seem to remember Simon Smart saying something about his pads/cradles were usually worth 2 watts, so someone has looked at the effect.

I think the problem is that when riders get into their truly preferred aero positions, conventional round extensions are rarely pressed closely to the riders forearms.
It appears that 3D printing has done several things here that simple metal extrusion can not easily do. In this case, 3D printing can make for extensions that have serious contortions which means the forearms and extensions can be so close together that they act as a single aero object. Plus, 3D printing allows the cross section of the extension to vary radically (from a sharp semi-circle to a roundish comfortable handle). Pretty cool.
It’s like the Crux design GB helmets… sure they’ll make you one, but there’s a reason no other country at the Olympics was using them despite them being “available.”

Yes. Maybe not those pads specifically.

I’m sure I’m late to the party, but I suddenly realized what a weird interface it is, and that it could probably be much better.
I suppose it would be tough to get stock solutions for different arms.
Just watched the stage. The aerobar extensions seem to completely disappear under Froome’s arms.

I’m sensing a business opportunity here. I don’t think the printing would be the difficult part, it would be get the optimal measurements to hide the extensions from the wind, etc. Oh and the cockpit wouldn’t be adjustable but who cares!
3D scan of rider. Then model the bars to fit! Then print. Then machine, polish and paint. Would be very expensive. I made 3d printed engine pistons that cost $9k each. Granted out machining was much much more complicated and precise than what would be needed here… But I did not have to scan anything first. The $9k does not include my time to design them.

I have a 3d printer… but it’s for ABS and other plastics… a Ti printer is another ball game all together… we are taking lots of $
Guess I’ll have to fabricate mine by using two sections of gooseneck (like on 1980s microphone stands) and have a friend bend those into place hidden from the wind. Then I’ll cast those with bronze just like I used to do in sculpture class, lol.

Titanium powder needs some extra precautions too, so I’m guessing some places wouldn’t want to deal with it at all.
Holy $&@!
THose are gorgeous

Yes.
And… I wish you could share.
