$65.00 CAD
Smooth Steering, Simplified.
Upgrade your front-end precision with the Promax IG-45 Headset. Designed specifically for frames with integrated head tubes, this headset eliminates the need for pressed-in cups, sitting directly into the frame for a cleaner look and easier maintenance. Featuring high-grade sealed cartridge bearings, the IG-45 is engineered to provide friction-free steering and long-term durability against the elements, making it an ideal choice for performance builds and reliable daily riders alike.
Why the Promax IG-45 is a Smart Component Choice:
-
Integrated Design: Specifically built for the IS42/IS52 standard (tapered head tubes), ensuring a perfect flush-mount fit that complements the aerodynamic lines of modern carbon and alloy frames.
-
Sealed Angular Contact Bearings: The high-quality steel bearings are fully sealed to keep out grit, salt, and water. The angular contact design is optimized to handle both the vertical and lateral loads of aggressive riding.
-
Lightweight Alloy Construction: The top cover and compression ring are machined from 6061 aluminum, providing high strength while keeping weight to an absolute minimum.
-
Low-Stack Height: The slim top cover helps maintain a low cockpit profile, giving you more flexibility to adjust your stem height and achieve your ideal "pro" position.
-
Universal 1-1/8" to 1.5" Compatibility: Designed to interface perfectly with tapered forks, providing maximum front-end stiffness for confident cornering and stable descending.

The Alegro Perspective: A headset is often the most overlooked part of a bike until it starts creaking or feels "notched." The Promax IG-45 uses industry-standard bearing sizes, which means when the time eventually comes for a service, finding replacement bearings is incredibly easy. It's a solid, dependable piece of hardware that does its job silently.
