Introducing the 52ASA – 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 52ASA brings the same arm-hugging benefits of our iconic shaped extensions, all at a more affordable price.
The core innovation behind both the ASC and ASA series is simple: shift the extension sideways to seamlessly align with your arm’s natural position, while keeping a 22.2mm mounting area to stay compatible with most standard aerobars.
