Oakland, California (November 2021) — The next logical application for Enduro Bearing’s Maxhit technology, after the successful launch of the company’s new Zero-Stack headset, is in their new Maxhit bottom brackets. Bicycle bottom brackets are known to be one of the most problematic wear components, primarily due to the limited space available for the bearings. Enduro’s patent-pending Maxhit bearing technology addresses weaknesses commonly seen with traditional BB components that utilize several parts within parts, including small-sized ball bearings that inevitably develop wear and corrosion issues over time.

Bottom brackets endure profound and intense forces transmitted through the crank spindle. To better absorb these forces, Enduro’s unique Maxhit design eliminates the aluminum bearing cups and increases the size of the 440C stainless-steel outer bearing race to actually become the BB shell interface. This patent-pending innovation allows for the use of considerably larger balls nested in much deeper bearing race grooves, providing more surface area to dramatically improve performance and durability.
Compared to industry standards, Maxhit BB bearing balls can have up to 8-times the mass and a larger bearing-race contact area to withstand more than double the force loads, leading to exponential increases in durability and performance. After months of Maxhit machine testing, Enduro is documenting a significant advantage in wattage savings compared to a range of leading brands also being tested. Already tested at over one million test cycles, the Maxhit bottom bracket has shown no signs of wear at all, while many other premium brand BBs have shown significant wear after a small fraction of that test duration. Enduro is so confident in the technology that Maxhit components include a lifetime guarantee – including against wear and corrosion – unheard of in an industry where most bearing suppliers only cover manufacturing defects for life.

“We knew Maxhit technology would be perfect for areas of high load on a bike,” says Matt Harvey, President and Founder of Enduro Bearings. “The headset was first because there are not as many standards, but we recognized straight away Maxhit would be a game-changer for bottom brackets as well.”
Another benefit of the larger balls found in Maxhit BB bearings is the ease of installation; for instance, preload can vary significantly from ‘very light’ to ‘very tight’ and still spin perfectly, unlike industry-standard BB’s which must be carefully installed to the perfect torque specification. Increased bearing contact area of the Maxhit design can withstand significantly greater axial (side) load than traditional BB bearings, making the Maxhit an extremely forgiving, dealer and consumer-friendly, BB solution.
