Profile Design 52 ASA Aluminum Aerobar Extensions

Size: 400mm

The 52ASA is the next evolution of Profile Design's 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 their 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.

With the 52ASA, they’re setting a new standard for “best value shaped extension” – a bold step in thier ongoing mission to deliver high-performance solutions for riders of all levels.

Performance

The sole purpose of extensions is to provide a comfortable position for the riders hands relative to the armrests. They enhance performance by allowing the rider to relax into their optimal position. Which is why we provide different fit options so each rider can chase their best performance.

Who is it for?

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.
