I remember someone saying that the S3 frameset was very heavy <1300g...
You are citing my measurements. I measured my S3 with seat-post, clamp, headset bearings, derailleur hanger and the super heavy through axles. I did not know how frame weights were measured here when I started my build thread. 8.2kg for my s3 build is respectable given I am using 105, 2kg wheelset, alloy saddle/bars, etc.

This is claiming 1100g frameset.

This one puts a size to the claimed 1100g (56) and weighed the fork 385g.

In the New Tour 7/2019 they tested the Cervelo S3, Size 56, Ultegra Di2, rimbrake Version, total wheight 7.9 kg (wo Pedals)
Frame wheight 1.243g, Fork 418g

Aero results for the S3 with original Novatec R5 Carbon wheels 211W
tuned with Zipp 404 wheels 209W
The Cervelo S5 was tested in Tour 1/2019 with 206W

So....quite small differences between current S3 and S5 regarding Aero results.
Do you have the stiffness number ?

It's apparently a good choice and the Novatec R5 pretty good.
