52 ASA Aluminum Extensions

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 the 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.

The extensions will fit in any aerobar that is designed for 22.2mm. So can be used by any rider wishing to improve the comfort of their aerobar grips.

Sold as a pair (1 Right and 1 Left Extension)
