Profile Design Sonic Ergo

The Sonic Ergo is designed to fit standard 31.8mm diameter handlebars. As long as your bars have a 31.8mm clamping area, these will mount securely.

The system is highly adjustable, offering an armrest width range of 124mm to 290mm and a stack height between 60mm and 130mm. With 1,500 possible configurations, you can fine-tune your position to match your specific biomechanics.

The 50-degree ski bend is a classic shape that provides a secure, natural grip for your wrists. It is particularly effective for riders who prefer a wrist angle that feels more neutral and less strained during long-distance time trials or triathlons.

Yes, the Ergo armrests feature a curved, supportive design that cups your forearms. This shape helps distribute pressure more evenly, which reduces fatigue during extended time in the aero position.

Absolutely. The armrests are flippable and adjustable, allowing you to tweak the width and stack height even after the initial setup. This makes it easy to experiment with your fit until you find the most comfortable and aerodynamic position.

The Sonic Ergo is a significant upgrade over older, bulkier brackets. It uses a minimalist design that reduces frontal surface area to lower aerodynamic drag while simultaneously offering a much wider range of fit adjustments.
