I think the titanium 3D printing technology is sufficiently advanced already to produce reliable parts. I know they have one at the CSIR here in Pretoria and I remember going to a talk about 3 years ago where they seemed to be getting good results. If I remember correctly, they were trying to print aircraft parts at the time, and seemed happy with the output they were getting. And that's at a state owned company in South Africa... I would expect that a specialist commercial company overseas could potentially be far ahead of us, and also would have proper quality control of printed items to ensure that wall thicknesses are correct and that layers have fused correctly etc.Ā 

Ā 

The over tightened bolt sounds plausible to me though. I mean even on carbon fibre, which is something we all trust without thinking, overtightening a bolt can cause catastrophic failure. Also, if there was an inherent problem with the bars, you'd expect that there would be more problems with them failing seen as the entire team has been training on them for months. 1 failure in a race points more towards an isolated problem rather than a problem with the component design or manufacturing itself.Ā 

#D printing of Metals for structural parts is still highly experimental. These bars were requested by the Australian cycling federation. Not many were made hence Bastion pulled the product from their site within minutes of the public failure.

Yes it might very well be an isolated failure but that could very well be due to inconsistent wall thickness. Printing a frame lug vs a thin walled highly loaded loaded part are two different engineering challenges. I'm sure that since the failure was so highly publicized a failure report will be made available once the investigation into the failure is concluded. It shoudn't take more than a few daysĀ  so we'll know soon enoughĀ

was mental. the Dane wasn't looking and wasn't expecting a laggard to be in the way. but still, chasing rider needs to pass safely. curious that the GB men's pursuit isn't so strong with the rest of their track team being so good

I was just watching this and wondering if dropped or slower riders have a responsibility to move clear of the racing line?

You can see other riders floating at the top of the track or on the inside.

But ja you would think even at WR effort through the red haze the Danish riders would have seen him in timeĀ

The 4th rider has to get out the way but the 3rd rider is still active(time taken on 3rd rider). The losing team holds the line and the winning team has to overtake them. Totally the Danes fault.

The decision to let them contest the final is correct though.

why did both teams not get a DNF? or at least the time of their 3rd riders, presuming they were still circulating? the danes were always going to win the race, and it's right that there's a gold/silver race tomorrow. after the tape-saga, GB reached into he cupboard to get out the axes to grind, but we all know how their axes stand up against viking axes

Ā 

I was thrilled to see Netherlands get team sprint gold.

My first reaction was that when the GB rider got up and finished that GB would go through but the commisaires decided that DK already won when they caught GBĀ (1m behind the rear rider is a catch apparently) so DK goes through.

That was really impressive.Ā  No 3D printed Ti on those bikes I presume!

Its very hard to look very far down the track with those helmets and the rider in optimum position. The Dane is also looking down at the wrong moment so there's that

I thought that was a rule anyway, but it makes perfect sense. it's the ultimate PK...

Apparently the Danish rider thought he'd crashed into the circulating GB rider, hence hisĀ being angry.

Ā 

denmark vs ganna for gold... should be excellent

to be fair, he wasn't expecting the GBĀ rider to get dropped. fortunately, the speed differential wasn't that big, so just a slip-n-slide
