Enduro Bearings is a company founded to improve upon the shortcomings of bicycle bearing technology, and this design philosophy is exemplified in the MAXhit Bottom Bracket. Created to provide elevated performance and longevity from your stock bottom bracket, the MAXhit Enduro Bearings Bottom bracket is machined from 440C stainless steel.

Stronger than the stock aluminum cups of standard bottom brackets and featuring proprietary double seals and high-performance grease, these bearings are designed to last. The company claims the MAXhit bearing balls have up to 8 times the mass of standard bearings, and withstand more than double the force loads.
Features
- Machined from 44C stainless steel
- Proprietary double-lip seals
- MSRP: $179
- Tested: BKSM-8112-Maxhit (BSA24 replacing Shimano XT)
Unlike typical bottom brackets, the bearing of the MAXhit is integrated into the bottom bracket itself – the bearing is the BB. The design allows Enduro to use much larger balls, and the company offers a lifetime guarantee.

Installing the MAXhit Bottom Bracket
The MAXhit BB doesn’t just look sweet, it’s a quick upgrade. A full assortment of spacers and seals is included in the box, and Enduro includes documentation on the optimal spacing.
For me, the hardest part of this test was deciding what bike to install them on. That said, with the claimed durability of the component, it could easily live on in a number of builds, being transferred from bike to bike. I selected my Stumpjumper EVO trail bike as the test rig as it’s been getting the most use. That said, I’ve been thinking about investing in a ti “heirloom” hardtail frame, (aka, a frame I don’t ever plan to sell) and this is the first component I’ll be migrating over.

Installed, the cranks spin smooth as silk. I was unable to detect any stiction whatsoever. The test of course though, is how they hold up after a few years of PNW winters. While the long term results are still pending, I’m pleased to report that after riding in cruddy conditions for a few months and spraying the bike down with the hose regularly, the cranks still spin with a feel as smooth as the day I bolted the BB on.
Admittedly, the Enduro Bearings MAXhit bottom bracket is an investment at $179, but if you put your bike through the wringer regularly, it could be just the ticket. Learn more at Endurobearings.com.
