The desire for more damping power is also satisfied, and with less stress on your hand, the GA2 Fat promises better control of your bike and more comfort. The core of the GA2 Fat has remained unchanged compared to its slimmer GA2. The outside diameter has increased. The increase resulted from more rubber, which has raised the comfort again significantly. The textures of the GA2 Fat MTB Grips are the same as the original GA2 and help to prevent forearm problems, arm pump and numb hands.
