I don't know why people get scared of them.
Comfiest saddle ever.
I've had several people converted after riding on one.
You probably have a svelte behind. Those of us with a more generous behind look at such saddles and just say hell no!

As for the bike...it's definitely something and it clearly works.

That is a gorgeous bike!

The seat angle caught my eye more than the construction, but you have just sat on it for 24 hours, it clearly works.

Are the thumb rests worth the 50 clams?

Togs should be $35.... And yes.
I cut my grips and run them slightly inboard so that I can rest on them all the time.

The speedneedle ramps at the rear. I find that it supports my hips appropriately

Which saddle again? I need to tilt mine down presently due to a lower back complaint.
PS those ti ss cogs, 3/32”?
Speed needle..
There's only the 19t left and I think so....

I've heard good things about togs. They'd be lifesavers on a 24hr race for the extra hand positions.

What a beauty! Totally crazy but in a good way

I use the Togs almost all of the time except for technical climb or descents

When you get the full replacement to the One9RDO, the thread better be called "The Final Solution".

On topic; is that wear on the Formula Stanchion near the seal? or just a quirk of the lighting?

Oh man.... So bad that it's good.
How would that go on the top tube?

Yes. Sadly these things can happen rapidly when you're doing silly things to your equipment like riding for 24hrs.
This fork is now more than 4 years old and has done 7x 24hr events now.

The conditions on the weekend were really dry (we've just set a record for no rainfall in Adelaide) and there was a huge amount of very very fine dust.
Despite wiping down every couple of hrs with a clean damp rag, drying and then re-applying stanchion lube, there's been some wear in the "sag zone" on the stanchions.
One of the best features of the Formula 33 is their plushness and lack of stiction. I run my forks super soft at 33% sag for a 24hr in 120mm travel mode and use extra oil in the air chamber to provide a ramping in the spring rate so that I don't bottom out.
This just means that the fork is constantly moving 10-20mm the entire time
