HSU Aluminum Alloy Curved Extension Arm Kit - Stable Helmet Mount

In this review of the HSU Aluminum Alloy Curved Extension Arm Kit, the bottom line is simple: this kit is for riders and action-sports users who want a lightweight, rustproof extension solution to place a camera farther from the helmet for better perspective. It stands out because the three curved aluminum arms and hollow design reduce wind resistance while offering several mounting lengths, making it a practical choice for motorcycle, cycling, skiing or skate sessions where a stable, extended helmet mount matters.

Key Features

• All aluminum alloy construction: The full metal build keeps the extension arms rustproof and rugged while remaining lightweight for extended use on helmets.
• Three length options: The kit includes 7.9, 5.3 and 3 in arms so users can tailor reach and framing for different activities without buying separate poles.
• Standard 1/4 in hole compatibility: Standard 1/4 in screw holes make the arms compatible with a wide range of action cameras and tripods as expansion accessories.
• Hollow curved design: Hollow sections and a curved profile help reduce wind resistance and improve in-ride stability for clearer footage.
• Layered end connection: The three-layer end connection provides a firm junction between arms so the setup stays steady during motion.

Who It's For

This kit is best for motorcyclists, cyclists, skiers and other outdoor athletes who already use helmet mounting and want more reach for better perspective or selfie-style framing. The lightweight aluminum and hollow design make it suited for activities where wind and speed are factors.

It is less appropriate for users who need a fully damped gimbal stabilizer or heavy-duty professional rigs; those requiring advanced vibration isolation or a folding, compact pocket pole may prefer a dedicated stabilizer or commercial selfie stick instead.

Pros & Cons

Pros

• Lightweight aluminum construction keeps added mass low for helmet mounting.
• Multiple arm lengths let you customize reach and framing for different activities.
• Standard 1/4 in screw holes provide broad camera compatibility.
• Hollow curved profile helps reduce wind resistance for steadier shots at speed.

Cons

• Some users report mixed build impressions, so extreme impacts may reveal weaker points compared with heavier professional mounts.
