The Sonic bracket offers an extensive fit range, low weight and easy adjustment along with minimal frontal area. Combining this with the Ergo armrest creates an aerobar that will aid most riders in optimising their position for both speed and comfort.
The 39a is one of the newest versions of our reliable aluminium extension range.
If you’re serious about triathlon or time trial racing, the Profile Design Sonic Ergo Aerobars are a game-changer. Designed for maximum adjustability, comfort, and aerodynamic efficiency, these bars give you the confidence to push harder and ride faster. Whether you choose the 26a, 39a, or 52a variant, you’re investing in proven race-day performance.
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.
