Solo Air is like a Buddhist monk. The enlightened design allows the positive and negative air chambers of your suspension fork to be filled with air at the same time using only one Schrader valve. So there is a perfect balance between them, like Yin and Yang. For a comfortable and predictable ride, you can adjust the easiest suspension fork on the market in seconds.

Motion Control is like riding on the moon. Gentle hills, crushed rock blasted out of craters. Crater. Unfortunately, you can't ride on the moon. But even on earth there is much inhospitable terrain. But SRAM has gravity, which means you need suspension that can handle climbs and descents equally well. With Motion Control damping technology, exactly that is possible. You can't ride the moon, but with Motion Control you can make gravity yours.
