Promax PI-1 Threadless Headset

Promax PI-1 Threadless Headset

The PI-1 Alloy 45×45 headset has an aluminum top cap, upper bearing cover, lower race and upper and lower cups. All-aluminum construction results in a lightweight headset. Each headset is fitted with super-smooth rolling, precision, 45×45 angular-contact sealed bearings.

Because this versatile headset has 45×45 angular-contact bearings, you can use the included cups and install it in standard frames. Or, leave the cup in the box, and use it as an Integrated headset.
