I'm not saying 25c is my ideal, but I ride what I have at the moment, and when I found myself on a gravel bit I have tarmac before and after. Plenty of people ride their road bikes on gravel in the summer with no issues (last year near Stockholm I was riding with a guy on a Venge and he smashed it). My point is actual gravel - you know, coarse sand, small stones - doesn't need or benefit from 2" knobblies, and the over-use of the moniker is tiring.
I think it's pretty hard to argue that a road bike with 25mm tyres is
a gravel bike.
Yet they make a much more relevant choice on smooth gravel than a MTB with drops or 13kg tourer with a 70 gear inches top gear.
