I do some fast road rides with them (~27mph) when everyone else is on 23-25mm tires. They are not that far off. Realistically they are in the range of 18 watts per tire (pretty similar to the Compass - Rene Herse tire mentioned above). Someone recommended Gatorskin 32, but that tire is going to be no faster (I know, I've tried). If you want to put a race oriented tire on your bike like the Conti GP5000, that will make a difference - and can cut your rolling resistance in half. But if you want a gravel tire for the road, that G-One is going to be hard to beat.

Agreed on the Schwalbe G-1's. My Niner RDO came 38c with them set up tubless, and they've been great tires so far. I ride about 50/50 road/gravel, and on the road they roll just fine. For serious gravel, I'll air them down to 40psi and they stick like glue. On the road, I've had no problem keeping a 20mph pace with my roadie friends on tiny 25c slicks.
