Cycling news reports that in the next Olympics the women’s RR field will be increased to 90 and the men’s will be reduced to 90.
Hmmmm

Great comeback from Roglic. I was wondering why he did so poorly in RR but apparently his injury was still affecting him right from riding from hotel to start line. Which begs question of Vuelta.

Nice comeback by Dumoulin as well, you can tell the Olympics are special to him. And if Dennis makes his advertised move to JV, all three podium spots will have been from them. Dumoulin meanwhile will be continuing to race but according to his own plan/program, which I don't think will involve GTs.

Van Vleuten also had good redemption from RR as well as from her Rio crash. Finally gold.

Pretty surprised Ganna didn't medal....course was probably too tough for him to win on, but thought a medal would have been a lock.
Just say "NO!" to WCP!!!!

Ganna scorched last year but this year has seemed pretty hit and miss. And yeah, tough course, some proper climbing.

I previously incorrectly speculated that post-Tour fatigue would affect the RR, which it didn't.
But Tour plus hard hot humid RR surely affected the TT.
Speculating some more: if Brandon McNulty had the same form for the TT he had for the RR, (and skipped the RR), could he have medaled?

Also just remembered he is doing track pursuit at Olympics. There was some speculation whether dual focus would affect road TT on hilly course. Perhaps it did and maybe same for Dygert. LSD agreed that Tour affected TT. Those guys carried form in RR but TT was one race too many as van Aert put it. The TTers cannot skip RR though, participation is mandatory although you can softpedal or exit early of course. Or maybe you can skip it but country loses a spot in RR.

Conner Fields' brain injury in the BMX - gives me the chills. Way too close to home. I couldn't do more than scan the CN article. Helmeted head hits pavement. Quick trip to one of that city's best. CT scan. Physical brain injury.

Been there. Only difference - when I did it the scanners had a vowel (probably to cover the much bigger radiation dose they had to give me). CAT scanner. Sounds like he didn't hit as hard as I did but that may be the benefit of a better collapsing helmet.

He has no idea yet what this could mean for him. Mine was the third biggest event of my life. (Birth, that and the second biggest hasn't happened yet.) Only in recent years has my early days begun to belong to me; not be just a story someone else lived and that I read about. I still run into situations that bring back entire chapters of my life that were completely buried until that trigger happened. (That night in bed I will be flooded with memories that for 44 years didn't exist.)

I wish him good support (and perhaps a real friend who will tell him what my best friend told me; that friends and family were not going to understand, that this would be far harder than I could possibly imagine and that she knew I would make it; she'd been through a very different but just as serious an accident.)

I hope he enjoys a fast and complete recovery. Tangent: impressive to me that BMX has grown so much that it's an olympic sport. It's easy to semi-dismiss it - the motocross racing it's derived from is less contrived, requires far more creativity, and top motocross racers are very fit, top notch athletes. But here BMX is on the big stage, on the same level as rhythmic gymnastics, half court basketball, and fat folks shooting guns and arrows and riding horses.

Fluid dynamics! The Danish pursuit team has been spotted with kinesiology tape strips down the front of their shins, clearly placed to trip the laminar flow to turbulent. The latest controversy.

For the past 45 years I've wondered why bike racers don't simple shave their legs in a Mohawk style with an unshaven or bristle strip down the front. (After all, shaving started as injury minimizer/clean-up facilitator and how often do we get road rash on our shins?)

Tripping the fluid flow to turbulent is not a new idea at all. I went to school for naval architecture in the early '70s. They'd been gluing sand to the first inches of ship models for towing tank testing for 70 years when I got there. The bible of aircraft wing design when I was there, "Theory of Wind Sections" by Abbott and Von Doenhoff talks about laminar flow peeling off wing sections early and and forming large turbulent wake so that despite the far lower laminar flow surface drag while it is attached, the net sum is far worse than if all the flow is turbulent. (There are wing sections designed to maintain laminar flow for most of the sections length that do best and where you go out of your way to make the front very smooth but we humans are far, far from that ideal. Maybe some birds, fish or whales/dolphins.)

When I've mentioned this to fellow cyclists, I've always been laughed at. Now I could start a trend if only I hadn't barked my shins so many times I'd have trouble growing sufficient turbulence trippers. It is time to shave 'em so I might give it a try but I doubt either the wind or adoring masses will notice.

And another broken CF stem/handlebar. A high profile face plant. (The Aussie team pursuit. Good thing is that he was on the back at the time. Got up and did the re-ride a half hour later.)

Printed Ti, not carbon from what I read.

So I saw elsewhere. Is there a black finish for ti? Also,what is a base bar?

From CyclingNews:

"For the Team Pursuit, the bike is fitted with an integrated aero cockpit. This cockpit consists of a one-piece carbon fibre base bar complete with an integrated stem, and on top, custom moulded carbon fibre aero extensions are fitted using aero spacers. The break appears to have occurred halfway along the stem area of the integrated base bar, with a clean break at the junction just after the stem area meets the handlebar."

That sure sounds to me like a CF failure. Now there was a lot of talk about a 3d printed ti cover but it seems to me from what I read that it wasn't the failure.

Looking at bike set ups the base bar is the bar extensions that sit below the TT bars. Presumably just used to get up to speed before hitting TT position.

Printed Ti, that’s interesting. An upgrade from stock carbon version it reads like.

Btw that kinesiology tape use, marginal gains hahaha. It seems to work. Basically it circumvents the UCI rule on sock height with aero socks supposed giving a 2W advantage.
