The Maxhit Zero-Stack headset is a unique patented Enduro innovation; where the bearing is actually the component. Maxhit headset bearings are designed to press directly into your bicycles headtube eliminating the need for the aluminum cups that are traditionally used to carry the bearings. This unique design frees-up space for much larger balls that more than double the load capacity compared to standard headset bearings. The kit includes fork crown race and upper split-ring upper bearing cap and a hidden topcap preload adjuster.
