Threadless headset Enduro Bearings 1-1/8" x 1-1/2" Maxhit Zero-Stack Stainless Steel

Enduro Bearings HDK-0010 is a 1-1/8 x 1-1/2 in. angular-contact, threadless Zero-Stack headset bearing kit. It fits frames with a 44/56 mm head-tube inner diameter and a 28.6–38.1 mm fork.

Maxhit bearings press directly into the bicycle head tube, eliminating the need for conventional aluminium cups. The design makes room for larger balls, providing more than double the load capacity of standard headset bearings. The kit includes a fork crown race, an upper split ring and an upper bearing cap.

The bearings are machined entirely from 440C stainless steel and are guaranteed for life. They use proprietary double-lip labyrinth seals and Enduro high-pressure grease for long-lasting, heavy-duty use.

The Enduro headset bearing range includes chromium-steel bearings with a black oxide finish and A/C contact geometry, as well as premium bearings made from full 440C stainless steel. The bearings are engineered with the largest possible balls and double-lip seals running in a micro-groove to protect against sweat and the elements. They are filled to 90% with high-pressure, waterproof grease. In Enduro Angular Contact (A/C) bearings, all balls engage to distribute force over a larger surface area, reducing the effects of water pressure and wear.
