Very likely. To me DB is Dave Wiens smashing it at the Norba

Now I get word that model has been cancelled Image
Did you buy one? Maybe no-one did.
They announced a spring 2018 release. Then word came they decided they would not produce it. So no, I didn’t purchase it. No one else did either as it was not produced.

+1!!
On one hand Manolo despite his dark sides (and never really forgave him what he tried to do with Indurain) was the one behind a lot of crazy things the ONCE did from a material stand point including many unique prototypes (if want to see some, join the FB group the uci's bandit bikes).

That was a carbon frame entirely made by Look.

Interestingly that was the race that buried Mavic ZMS, all due to a bad grounding because of the carbon frame behaving like a capacitor... Zülle lost the 3rd place to Delgado in the last TT

This frame was pretty radical. I've never seen anything like it before or since.

That one was welded at Ciöcc, in Bergamo

What is that frame called that a guy created out of a washingmachine? Crouch? Was really fast on it as well!

Partially inspired of Obree frame design with a classic geometry. The high angle tubes cause less drag than more “vertical” ones.
In the 90s Bianchi had quite some interesting designs most of them made out of Columbus Hyperion titanium tubing.

Those two prototypes were for Bugno but never saw them in use, the disc brake with radial lacing is very questionable

There’s a nice video of O’bree here - https://www.youtube.com/watch?v=oJ9H0INZ2_s

Turns out his design is more aero than modern stuff. Imagine that with some tube shaping, modern aero wheels and kit!
I'm left handed, if that matters.

I love this. I think his position was much more aero

I rode a Softride Rocket TT for many years and loved the look and the plush ride of this radical frame. I am not sure which came first, but Trek followed/lead with the Y foil frame and Titan Flex was around the same time frame also.

Would it work to use a 24 hole hub (12+12)?
- Use all 12 holes on the drive side
- Use only 8 of the 12 holes on the left side

The 8 used holes would be uneven around the hub but could be chosen so there's no net torque.

Maybe 12, 6, 3, 9 (even)
and 11, 1, 5, 7 (uneven, but symmetric)?

Looks like a quiz for a lazy Sunday... ;-)
That might be usable, but how about a similar pattern on a 32h hub?
- 12 uneven but symmetric on the drive side
- 8 even on the non-drive side
That should allow for perhaps better pattern on the weaker side (with less spokes).
