The increased arm wrap and surface area improve ergonomic comfort, helping riders push on longer. Textured neoprene pads ensure reliable grip and cushioning through long rides. Designed to integrate seamlessly with nearly any aerobar, including compatibility with TriRig Alpha One and Speed Concept hardware, your fastest setup can be a reality. The Closed Back SL Carbon Arm Cups are a standout upgrade for athletes aiming for their fastest, most comfortable position.
