what does the seat of the Silvio 2.0 weigh?

[counterpoint]

Wondering what the seat weighs as replacing it with a Volae all carbon seat might offer substantial overall weight savings.

May be somewhat moot given that a carbon seat is supposedly not just under consideration but in the works.

I'll be able to weigh mine once my frame set arrives mid November but perhaps someone knows the answer.
The computed weight of my build is 24.5 lbs (corrected) (with heavier disk brakes).

11.5 Kg?  (11.5 lbs would be

11.5 Kg? (11.5 lbs would be amazing).

I'll point out that even if the weight savings is a pound, buying a carbon seat for lower weight isn't a great use of money - it's total weight (bike + rider) that matter and that's really only when climbing.

If you want the Volae carbon seat because it's more comfortable, that's another matter...

climbing indeed

Saving a pound (if possible) would be substantial. The seat would be just about the only place where you could bring the weight down.

I live in the foothills of the Colorado Rockies on a hill, so there is literally no ride I can do without climbing.
I used to own an Actionbent recumbent that weighed 36 lbs - and hated it. When I moved back to Boston for a year it was fine there but I switched to a 23lb Corsa the day I returned. At that point, riding was fun again. This was the day after returning from a year at sea level, 8 lbs above my normal weight after a summer of inactivity, yet I zoomed up Lookout Mountain 10 minutes faster than on my wife's low weight race bike.

I contend that it really really matters whether you ride a boat anchor or a feather weight. (Light weight wheels are a key factor).

Of course, now I'm completely spoiled with a Carbent Sea Dragon at 19 lbs: I no longer worry about the terrain.

By the way: a small outfit in Germany went back to the roots - or woods rather - and came up with an 800g/1.8lb wooden seat made of pine: below the typical carbon seat weight for under $100.
I'm going to order one just for the heck of it (it might get here faster than my frame).

and the weight is--

Just the two plastic pieces: 1 pound 9.75 ounces or 730g.

Whole ball of wax, seat , spacers,bolts, cushions: 2 pounds or 908g.

If braking power is your concern I would skip the disk brake in the front. The current brake causes rear wheelies as is.

wheelies?

The weight of the seat is impressively low, no wonder they've not made developing a carbon version a priority. On my Bacchetta Corsa the carbon seat gave massive weight savings.

The reason I went with disc brakes was that I got carbon wheels and didn't want to take any risks with rim brakes which tend to overheat, even disintegrate on long descents (or so the horror stories go).

I ordered two kinds, the Hy/Rd hydraulic (cable actuated) and the mechanical Spyre disk brake. I can always put the lesser one on the front. But hydraulics supposedly have lots of modulation. I used to own a high end Counterpoint Presto with Magura hydraulic brakes and they were indeed smooth, allowing you to decelerate OR stop.

Seat weight

Hi ?counterpoint.

Your seat looks nice. But 800 g seat isn't (from my point of view) the lightest one. My friend created for me M sized glass fibre seat of about 700 g. And it may be created even lighter (~600 g) when you sacrifice some torsion stiffness. What I cannot do because my seat is structural part of my frame.
