Run a tapered fork in a frame with a 44mm head tube top and bottom. Enduro's Maxhit kit uses 440C stainless bearings that press straight into the head tube, making room for much bigger balls; Enduro says that more than doubles load capacity over a standard headset bearing.

Highlights

• Zero stack / external cup kit for 44mm upper and lower ID head tubes
• Takes tapered 1-1/8 to 1-1/2 steerers
• 440C stainless steel angular-contact bearings with double-lip labyrinth seals
• Filled 90% with Enduro's high-pressure waterproof grease
• Matched 36° crown race, split compression ring, bearing cap and hidden top cap preload adjuster
• 17.9mm total stack, black finish

Why Maxhit

Conventional headsets carry their bearings in aluminium cups. Maxhit bearings are machined entirely from 440C stainless steel and press straight into the head tube, so the bearing is the component. That frees up room for much larger balls, and Enduro says the result more than doubles load capacity compared with standard headset bearings. Double-lip labyrinth seals and a 90% fill of high-pressure waterproof grease keep sweat and weather out.

One matched 36° system

Every Maxhit headset uses a 36° inner race chamfer with a matching 36° compression ring and 36° crown race. Enduro notes that angle differences from your original headset won't affect function, as long as all the supplied parts (bearing cover, compression ring, upper and lower bearings and crown race) are used together as a set.

What's in the kit

Upper and lower Maxhit bearings, fork crown race, upper split ring (compression ring), upper bearing cap and a hidden top cap preload adjuster.

Compatibility & fit

Fits frames with a 44mm ID head tube at both ends, with forks running a tapered 1-1/8 to 1-1/2 steerer. Total stack is 17.9mm: 6.5mm at the top and 11.4mm at the bottom, so check your fork's steerer length and front end height before you order. Headset installation is a separate workshop service, and our workshop has the press tools to fit it for you. Enduro's warranty also asks for an annual clean and re-grease by a qualified mechanic, which we can do at your next service.
