Friction facts say 6 watts loss for 48:10 vs a 53:11 at 250. I’m more curious what that loss looks like at 1000 watts for 20-30 seconds because I don’t know anyone riding in that gear at 250 watts. I wouldn’t care so much about 1-3 watts being in the middle of the cassette, but if I were losing 100 watts across a 30-second sprint, that’s enough to make me stay with a 53 front ring on the road at least. 1x for gravel still strikes me as the ideal, and a 42x10-44 ekar sounds about right.
