Promax IG-45 Integrated Headset

This is an integrated headset designed specifically for frames with an integrated head tube. It is compatible with 1-1/8" steerer tubes and requires a 30mm crown race diameter. Please verify your frame's head tube specifications before purchasing to ensure a proper fit.

Yes, the Promax IG-45 includes the necessary components for a standard installation, including the sealed bearings, an aluminum bearing cover, and the crown race. You will need a headset press or appropriate tools to seat the components correctly into your frame.

The 45x45 degree angular contact bearings are designed to handle both radial and axial loads simultaneously. This configuration provides a smoother steering feel and greater durability compared to standard cartridge bearings, as it effectively manages the stresses placed on the headset while riding.

The total stack height of the Promax IG-45 is 35mm, with an upper stack height of 20.8mm and a lower stack height of 14.2mm. Keep these measurements in mind when sizing your steerer tube or determining your stem height requirements.

The IG-45 uses sealed cartridge bearings, which are designed to be low-maintenance and resistant to the elements. While they are not typically serviceable in the traditional sense, they are easily replaceable if they eventually wear out, allowing you to refresh your headset without replacing the entire assembly.
