On first look it seems like the Argon base bar. After a closer look it seems like the Bastion one.

https://www.cyclingnews.com/news/austra ... rts-claim/
That article is both wrong and based on nothing, the base bar is an Argon part. The author would know that if they'd even seen the inside of something bastion have made.

What was on their website were the base bar risers that went with the printed aerobars they make.
Fair enough!
Sure about that? full honeycomb structure would surely be too heavy

I am not sure. However we know the Hope track bike has 3D printed titanium bars and fork top sections and the GB team certainly keeps an eye on weight.

3D printed Ti has a very characteristic structure inside due to the scafold used for printing. You can see it in this artlcle.

I think this is why Pierre86 says this is not a Bastion 3D printed part and I would think the same also.

Friggen called it.. Knew that pos would get a slap on the wrist for his blatant racism.

Looks like where ever he is now it's very difficult to find a device that can transmit voice in real time.. Or ones that does live pictures to offer an personal apology to the two Olympic athletes he insulted.

BDR has become such a sad travesty. I for one won't be renewing my license after the season ends.

Yep, totally get that. The broken bit is clearly carbon, my bad. Just saying that printed ti isn't too heavy for bars because it is being used for bars on other bikes.

You feel sorry for them riding behind two massive windbreakers? I don't get it. It's riding behind tiny people that sucks, surely :noidea:

You've never done a TTT. Being second wheel for as long as Ganna was pulling = no rest for someone significantly smaller.
Explain.
Becasue Ganna is putting out so much power that even being in his slipstream isnt enough to offset the difference in power between him and 2nd wheel

Maybe it makes sense when actually being ridden. We'll soon find out.
Did not help in the slightest, at least in the first round

How about that crazy crash of Alex Porter!
Basebar just snapped and he went face first into the boards
Was watching it live when it happened and I still cant believe he got up and walked away from that.

Had skin taken off his nose (from bridge to tip!) and his chin.

Helmet definitely saved him from an extremely serious injury
Probably doesn't belong here...and definitely hyper-sensitive, but I'll pass this along:

Appx a month ago, I hit a pot hole and crashed. I don't remember any of it. The aftermath was my helmet was crushed (as they're supposed to). I was able to track down the person who called 911 and thank him. He told me that he saw me laying aff the side of the road "out cold," but by the time he parked, called 911 and got to me, I was starting to come around. Apparently, I stood up, grabbed my bike, and said "I'm fine...I'm just gonna ride home." He said another person arrived by that time and they both were talking to me to get me to stay (and holding my bike so I couldn't leave). He told me they just kept talking to me about anything...to distract me from leaving until the ambulance got there. In addition to a shit-ton of other injuries, I had brain bleed and a concussion.

My point is: 1) my helmet definitely saved me from serious head injury (THANK YOU POC) and 2) maybe we shouldn't let people get up and walk away...much less ride away. I don't even want to know what would have happened if those people said "Ok....have a nice ride." They may have, quite literally, saved my life.

I'm not saying it's the case for this one particular crash, but how often do we see pro cycling crashes where we're amazed that they get up and walk or ride away....only to also see how wobbly they appear on their bike.

Sorry for the distraction from the pro thread...it's just really fresh with me right now. :(
First of all, hope you are OK and have no lasting injuries.

I was watching the Oly teams pursuit live when this all happened.
Alex did get up quickly and was like "WTF just happened?"
I did see the team doctor giving him a test looking for concussion before they went back out on the track, but yes, I did have the same thoughts if he should really be back out there after I watched him walking off the track and they showed a close up of his face and it was obvious he hit the track face first and the skin he had lost from his nose and chin

Once at Superweek, I was single file behind a 6'6" dude who was reputed to have the highest power output of anyone ever tested at U Texas. His saddle was so high that even though I'm over 6', I felt like my upper body was below his ass, and consequently, it didn't feel like a good draft. Might have also been the fact that we were going 35+mph at the time. Can imagine the same effect with Ganna.

Being second wheel in a paceline isn’t nearly as nice as being third or fourth…especially when the guy in front is doing 90s turns instead of 30s.

If one guy is going too fast for the rest of the team it's an error in pacing and turn lengths, not a natural consequence of him being too tall. And if one guy is going too fast, it's still better for the others if he's tall rather than than short.

It's a weird situation with disproportionate power output. You have to experience it to really believe it. 2nd wheel has a noticeably smaller draft benefit than 3rd wheel. 3rd wheel and 4th wheel are much closer. So whoever was behind Ganna had to sit 3rd wheel on Milan's massive turn *and* the start of Ganna's. He obviously couldn't handle it and peeled off. I've done the same sitting behind our U23 who has something like a 350w FTP compared to my 295w. He'd pull off and I would pull off at the exact same time. It was still beneficial because I was a buffer to the next rider. He would do 90s pulls and I would do 0s-15s pulls after him even though I was the second highest w/kg in the group.

But don't take my word for it if you're skeptical.

2008ish?

Was this guy a former rower that was later busted for doping?

If so, I was likely in that race, too.

I see evidence of the lattice in the closeups and also have doubts that 1) a composite basebar would have such thin walls plus 2) break so cleanly without splintering or leaving folds/flaps.

Plus if the basebar is made in two parts, then the internal lattice can be removed after printing.

As well all their other parts for the AU track team are 3D printed titanium, such as the cranks, madison / sprint bars and stems. Also AFAIK, Bastion’s carbon is all filament-wound and basic tube shapes (frame tubes, fork legs, etc.) the basebar is pretty intricately shaped.
