HDK-0022-S - 1-1/8 x 1-1/2 stainless steel, Angular Contact, Zero-Stack/External Cup Headset Bearing Kit for 44mm/44mm ID head tube framesets - SilverAll Enduro Maxhit headsets are designed with a 36º inner race chamfer angle, along with a matching 36º upper compression ring and 36º lower crown race.When installed as a complete system, angle differences from your original equipment will not affect functionality as long as all included components are used together as a set. This includes the bearing cover, compression ring, upper bearing, lower bearing, and crown race.Maxhit 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.Machined entirely from 440C stainless steel and guaranteed for life, Maxhit headset bearings include proprietary double-lip labyrinth seals and Enduros extra high pressure grease to ensure a lifetime of trouble-free, heavy duty performance.The Enduro line of headset bearings begin with chromium steel, Black Oxide finish A/C type and then offer full 440C stainless steel at the top. They are always engineered with the largest balls possible and dual lip seals riding in a micro-groove for ultimate protection against sweat and the elements. They are filled 90% with high pressure water proof grease, so you never have to guess if there is grease inside. Enduro Angular Contact (A/C) bearings, all balls are engaged to spread the force over a larger surface area, pressure water and minimizing wear.Total stack is 17.9mm (6.5mm upper and 11.4mm lower). Both upper and lower bearings have 36° inner chamfers.
