Introducing the 52ASA Ð 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 sole purpose of extensions is to provide a comfortable position for the rider's hands relative to the armrests. They enhance performance by allowing the rider to relax into their optimal position. This is why we provide different fit options so each rider can chase their best performance.
