Double-butted wall thickness shifts damping toward the outer edge where vibration hits hardest. The GA3 from Ergon uses varied rubber thickness across the grip body to soften trail chatter without adding bulk. The mini-wing extends just far enough to support your palm without interfering when you need to move your hands around on technical descents.

The wing addresses carpal tunnel pressure that builds up when your wrist bends too much on the bars.
