The guy third from the left is Roy van den Berg, a few stats for you, https://www.beatcycling.club/en/team/?filter=pro-team

Particularly like his squat PB of 265kg!

...and 2,715W.

R.I.P. cranks and pedal spindles.

How do they wear pants?

Lol, good call.

Looks like it was a gift from Pinarello for winning Olympic Gold:

Good interview with Dan from Team KGF

https://www.velouk.net/2017/11/17/fe...gham-team-kgf/

That's a great interview. Lots of good info!

!!!???!!!

Jeez. Built in 2003...and has never hosted a race...even a local one.

It's a Schüurmann track to boot. This is CRAZY.

I missed this post. Thanks!

Wow. The Zipp 808 + Sub9 Disc rode faster than Mavic Double Discs?!

I’m around the same build as him and I’m nowhere near his cda

Yeah I think it's important to note that the 19c vittoria pista tires were at 200psi for testing and would have likely been faster at a more reasonable 140-160. Not sure if they still would have been as good as the clinchers. I'd also be curious how the T4 would have done with a mavic disc in front and the Zipp in the back.

I'd really like to see how fast a tubular wheelset would be with a fully hardening cement vs. clinchers like he used. There are not insignificant losses with tubulars due to the fact that the tires "squirm" against the rim. Of course this would be feasible only for a big event as its not very reliable over time and a huge pain.

Straight up shellac makes for the lowest rolling resistance when itcomes to gluing tubs. Next in line is 3M FastTac. Those would be what you want to test with. On a well made wooden track you can go much higher on psi because the tire doesn't have to deform like it does on concrete or asphalt tracks.

Yup. And the Tubular version of the Zipp Super 9 ($2700) is the Zipp 900 tubular and that wheel is $900 less than the Super 9 at $1800.

I think the biggest takeaway is that if you go straight tubular:

Zipp 808 Track: $1100 MSRP
Zipp 900 + Track Axle ($100): $1900 MSRP
Total: $3,000

is on par with:

Mavic Comete Front: $2,900 MSRP
Mavic Comete Rear: $2,900 MSRP
Total: $5,800

That extra $2,800 can be put to use in other ways to make a sprinter or pursuiter faster. Upgraded helmet, bars, frame, coach, wind tunnel time, etc... That's real.

BONUS: It's uncommon to use the Comete front outdoors and for mass start. It's very common to use the 808/900 combo in any conditions.

There’s a tubular super-9 as well, it’s wider than the 900 and a bit stiffer but still flat compared to a comete.

Worth noting he used a road 808 with a bolt on skewer. Track 808 has two more spokes and a higher flange hub and may not be as fast, though stiffer.

Ah. thanks! I get confused by their product naming convention and whatnot. They should just call it "Zipp 900WT" (W for wide, T for tubular).

If we saw:
- Zipp 900T
- Zipp 900WT
- Zipp 900C
- Zipp 900WC

We'd instantly know what it was.

I still don't know what "Firecrest" means.

So, what your correction, the Super 9 Tubular is $2400, $300 than the one tested.

Also, let's say we mixed and matched the Zipp discs and 2 808s mentioned above, I think the takeaway would still be the same: A Zipp wheelset is significantly cheaper (at least $1000 and as much as $2,800 cheaper) and on par with the combo that is widely considered the fastest in the sport on the track.

One would expect to see dramatically slower numbers with the "basic local racer" Zipp wheels...and that's simply not the case :D

At one time, I had Zipp 808 Front Track, Zipp 808 Rear Track, Zipp 900 and I sold the 808s to help pay for an IO/Comete set and I gave the 900 back to the guy who loaned it to me.

Had I known what I know now, I would have kept them and saved my money.

This is correct.

Zipp's "Firecrest" technology is the previous generation of torodial rim shaping. Their first foray in to the WIDE carbon wheels. That is being phased out now in favor of "Firestrike," which if I've understood correctly, is even wider, with some more improvements to the clincher brake tracks, and some minor tweaks to the rim shape.

I'm a pretty dedicated SRAM guy, but don't EVER expect them to give you a simple nomenclature system. That said, once you learn it their system isn't SO bad.

actually i think Zipp has one of the better naming schemes for their wheelsets - or at least their rims (They don't do wheelset name changes when they do hub changes, which is probably pretty good since the rim is the most significant feature). They have a number designation that corresponds to depth and stays consistent even when they change the model (before they had changed the number, like from 440 to 404, or hadn't changed the number even when the model changed - like when 404s got dimpled). And then they have a model/shape designation (Firecrest, NSW) that's consistent across depths (454 NSW, 858 NSW).

Lets consider the found difference is under the process error margin - but if we can believe there's no noticeable difference between the 808 and the Mavic disc on the front, why use it - a disc - at the rear very turbulent flow?
Why not using both 808 of some other rigid high profile rim?

An additional question - why Shimano stopped to build the 4 Rays (much lighter than the 5 spoke)?
Would you sprint on a 4Rays?
Would you make a stand start/stand up TT turn acceleration on a 4Rays?
Like this one - https://produto.mercadolivre.com.br/...o-4-pontas-_JM

Yup. Lots of people were sprintin on the Corima 4 spoke and Corima disc before Mavic started to sponsor all the top national teams. Shimano probably stopped making theirs because there weren't enough people buying it.

Found the Aussie seat manufacturor when looking for the new aerobatic.
askil
The new bars are used for pretty much races only, they don't warm up on them during competition are designed for each rider and to work in tandem with the aero gloves. They're supposed to take advantage of the maximum lenghts permitted as the extensions are on held by the ring and pinky fingers leaving the rest of the hand to be shaped aerodynamically.

Took some screens of the posts to show the difference between qualifying where they rode a 3.57 to the gold run which was a 3.52 at the oceanic champs. It's pretty cool stuff so I'll get in my mates ear again and see what I can find out haha
