I have an S type and also a basket for large loads but fine when empty it interferes with the brake levers a bit, so I tie the two handles together and that helps. When full this isn't an issue. Anyone else find this and have a better solution? That bag will hold an amazing amount of stuff without affecting the handling but it sure does slow you down in a headwind. As Bargain Guy said, I have made a couple of bags of different sizes which work fine for different loads and are both a little more aero. I also bought a cheap nylon bag for the Army Navy store and stiffened it with a back of 1/8 inch plexiglass to hang off the saddle. This is enough for light things and since stout winds are everyday here it doesn't slow the bike since it is behind it.
