I like Schawalbe Racing Ralph’s and Maxxis Ardent Race for a capable knobby that rolls fairly well. Although both of these are 26” tires…I know, I’m a luddite…they are available in 622mm sizes as well.
The Ardent’s are fast enough that I was able to do 12 mph average over a 40 mile route that included 5 miles of barely moving uphill (including 10% to 20% grades) and 2 miles of riding railroad ties.
