Profile Design 52 ASA Extensions - Product Description

Achieve a seamless, arm-hugging aero position with the Profile Design 52 ASA Extensions, available at Arvada Triathlon Company! These high-performance aluminum aerobar extensions are the next evolution of Profile Design's wildly popular Aero Shaped Carbon (ASC) series, now offering the same ergonomic benefits at a more accessible price point. Crafted for triathletes, time trialists, and road cyclists, the 52 ASA features a 52° grip angle and advanced multi-stage forming process to align perfectly with your arms, reducing drag while enhancing comfort and control during long efforts or high-speed races.

The 52 ASA's innovative design shifts the extension sideways by 7.5mm per side, allowing for narrower or wider hand positions without excessive tilting that could interfere with shifters. With a 340mm length and increased rise for modern higher-hand trends, it promotes relaxation—the key to sustained speed. Compatible with any standard aerobar accepting 22.2mm mounts, these black aluminum extensions weigh just 236g per pair, making them lightweight yet rigid for optimal power transfer. Whether upgrading your tri bike or fine-tuning your road setup, the 52 ASA delivers pro-level aerodynamics and fit versatility to help you shave seconds off your splits.
