Thanks guys I feel the crushed stone surface is not helping the situation. I guess I'll be riding the greenway for a while. It's just the ATT is so close and not a hassle to get to but I'll suck it up! LolAvoid at all cost. There used to be a vendetta rider with a long crushed stone driveway... it was such an irritation he decided to sell his Vendetta.
You have to travel slowly and the bike becomes a little unstable... then you dont want to trash your cleat and beautiful shoes on the stones... quite a dilemma.
The surface used on most rail trails I believe is called crushed granite screenings. It packs almost as hard as asphalt when wet or damp but has tendencies for having loose spots in very dry weather.Different people mean different things with trail, crushed, stone, path, gravel, etc.
3/4" gravel like the stuff on the shoulder of the road, base under a driveway, especially if loose, is brutal to ride on any bike let alone a skinny tire racing recumbent!
Gravel Dust, coarse aggregate, crushed stone would be better but still not great for learning, not too bad when dry and smooth once you are comfortable but not an ideal learning environment.
