Introducing the Sonic Ergo+ 52 ASA – the next evolution of our wildly popular Aero Shaped Carbon (ASC) extensions, now available in a sleek, high-performance aluminum. Crafted with an advanced multi-stage forming process, the 52 ASA extensions brings the same arm-hugging benefits of our iconic shaped extensions, all at a more affordable price.
Our 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 optimizing their position for both speed and comfort.
The Ergo+ Armrest takes the shape of our popular Ergo armrest and lengthens it to 124mm to increase the contact surface for your arms, thus lowering the pressure on your skin even further.
The 52 ASA is one of the newest versions of our reliable aluminum extension range.
