I’m sure I’ll regret this, but what’s “Crr?”

I'm not sure what the C means, but the rest is Rolling Resistance.
EDIT: Found it...Crr = Coefficient of Rolling Resistance. |
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!

The C stands for coefficient. It's the number by which RR (rolling resistance) is multiplied to arrive at the total amount of energy lost.

Either way, it’s the best spoon material. |

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? :D |

Asking for a friend. |
When you commission a full carbon monocoque Mixte. And not a gram before that.

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. |

At some point, the bike gets so light you cannot get to the bottom.

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.

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.
