Rear suspension - coil vs. air

The biggest advantage of the air suspension is in weight savings. Second, as the shock is more progressive, there is less chance of bottoming out. Also, it is easier to adjust amount of preload on an air spring - just pump in more air.

Performance wise, coil gives more linear, smoother performance. Bottoming out is more of a possibility.

The bad thing is that if valve in the air shock fails, you are in trouble. There are kits to rebuild the shock, so it is possible.

Bottoming out is more of the MTB issue, where riding and jumping is much more aggressive. On a recumbent, that is not an issue, as long as the spring is in the ballpark of the load.

In my opinion I will stick with a coil shock.
