The Profile Design Sonic Ergo 39a Aerobar is built for riders who want the perfect balance of comfort and speed. With its 39° ski-bend extensions, it offers a natural hand position that reduces fatigue while keeping you fast in the aero tuck. Lightweight, highly adjustable, and race-ready, the 39a is designed to fine-tune your fit so every ride feels effortless yet efficient.

Why Choose 39a?

  • Balanced rise for both comfort and speed.
  • Excellent for middle to long-distance triathlons.
  • Highly adjustable to suit multiple riding styles.

The 39a provides a more relaxed wrist angle compared to the 26a, reducing arm strain during longer events while maintaining aerodynamic benefits. Precision-crafted for stability at high speeds.

When selecting aerobars for triathlon and TT bikes, the 39a variant hits the sweet spot — pro-level performance with enough rise to keep you comfortable on endurance courses.

For over 30 years, Profile Design has led the way in triathlon innovation. Their products aren’t just built — they’re engineered with precision, tested in the most demanding conditions, and trusted by elite athletes worldwide.
