Would you agree that weight at the rims or tires only matters 2x as much as weight on the frame and elsewhere when accelerating? If you agree with that, then we're on the same page.

So, an ounce on the rims or tires truly is worth two on the rest of the bike, with respect to acceleration (only).

I haven't taken part in this dicussion here (BF) before but I get the feeling it's been hashed and rehashed, so maybe I should shut up now. Not trying to have the last word, please go ahead and tell me where I went wrong.

Yes, only during acceleration, I agree. I don't think you went wrong anywhere, fwiw. But there is history from a previous thread where the simple factual impact on inertia was denied, etc., etc.

A concise statement of the impact on inertia was what I meant.
Perhaps "When you're trying to go faster..." is the click-bait version.
