This one (88 RockHopper) goes great on road, crushed stone trails and actual gravel roads.
This one (85 Schwinn Sprint) is great on roads and on crushed stone trails when they are reasonably dry and firm. I don’t take it on real gravel because I have the RockHopper.
And that’s it. No bikes that can’t at least tackle crushed stone trails.
Oh, I’ve run them both with drop bars, but running SS, I prefer these touring bars that offer more versatile positions to ride while standing.
