Maxhit is Enduro’s latest patented innovation, where the bottom bracket bearings and cups are merged into a single integrated component, eliminating the need for separate aluminum cups. Maxhit bottom brackets are essentially bearings designed to thread directly into your bicycle’s bottom bracket shell, without mating interfaces that can create unwanted noise such as creaking. This unique design also frees up space for significantly larger balls, more than doubling Maxhit’s load capacity compared to traditional aluminum cup bottom brackets.

Machined and ground entirely from 440C stainless steel, Maxhit bottom brackets incorporate proprietary dual-lip groove seals and Enduro Speed Grease, a high-pressure grease which ensures trouble-free, heavy-duty performance. They also include a selection of seals and spacers to ensure proper installation in any T47 threaded frame. Maxhit bottom brackets are built for extreme durability and are backed by a lifetime warranty, requiring only periodic cleaning and regreasing.

All Enduro Maxhit components are covered by a limited lifetime warranty against corrosion, wear, and manufacturing defects.
Annual professional servicing is required using Enduro Speed Bearing Grease (GR-011).

This is just one example of the extensive range of solutions Enduro offers for the wide variety of bottom bracket standards on the market today. Enduro provides options for nearly every configuration at multiple price and performance levels, including high-carbon chromium steel, black oxide-treated, 440C stainless steel, ceramic-hybrid, and ceramic-hybrid with XD15 super stainless steel race options. Our bearings are engineered with the deepest groove raceways possible to accommodate larger balls, and feature dual-lip seals that ride in a precision micro-groove, creating a full labyrinth seal for long life and superior protection against the elements.
