I have heard it said that 1 pound of bike weight is equivalent to 20 pounds of body weight. Further, 1 pound of rotating weight is worth 30 pounds of body weight. So I think I should buy some CF wheels and to hell with the diet!

Finally! An ism beginning with weenie!

How about when you spend $15K to get a bike that's only six pounds lighter than Eddy Merckx's gas-pipe garbage scow with the cables flapping in the breeze?

Asking for a friend.
At some point, the bike gets so light you cannot get to the bottom. (Think blimps.) So weight weenie madness is never achieved. (Never stopped anybody from trying though.)

The difference in Crr between a Conti 4000 and Conti 5000 is equivalent to a mass difference of about 500g on a 7% hill. It's equivalent to a 150g mass difference on a 25% hill.

This is true. I’ve replaced so many parts on my bike that at this point, there isn’t much more—or maybe anything— left to change.

We went in just short of the weight limit, er, he went in, and adjusted final weight based on the official scale.

Titanium is too heavy; use aluminum.

In related news…I bought a gravel bike a little over a year ago, and immediately started swapping parts to suit my preferences and trim some weight. A couple of months ago, I got a new frame and swapped the parts from the first frame, plus a couple of additional upgrades. I’m pretty sure I can rebuild the original bike with all of its original parts, just as I bought it.

Thing is, I’m not changing my frame. Ever.

Understood. When you have a grail frame, you build it to your personal version of perfect.
