While many consumers may loathe the number of bottom bracket standards, for brands like Enduro Bearings, it allows them to do what they do best – provide options for more durable bearing upgrades.
First introduced as an option for headsets, Enduro’s Maxhit technology improves bearing durability by allowing for the use of bigger ball bearings. This is accomplished by getting rid of the aluminum cup traditionally used to hold the bearing. Instead, Maxhit products use a high-grade 440C stainless steel cup that is machined to house the ball bearings directly, eliminating redundancy and providing more room for bigger balls. According to Enduro, “Maxhit balls have eight times the volume of standard bearings to dramatically improve spinning characteristics and durability.”
Our personal experience with the Maxhit seems to confirm Enduro’s claims. I installed one of their Maxhit BSA bottom brackets for a friend who was chewing through bottom brackets on his fat bike. Nearly a year later, the Maxhit BB is as smooth as the day we installed it, already outlasting his originals.
In 2021, Enduro added the technology to select bottom bracket standards. Now, that same tech is making its way to T47 bottom brackets with nine different permutations. Those nine options include three frame configurations for Internal, External, and Asymmetric bottom bracket shells. Then, each of those three configurations has bearings options for three spindle sizes with 24mm (Shimano), DUB (SRAM), and 30mm.
The T47 bottom bracket standard was already supposed to offer larger bearings with better durability, so with the addition of a Maxhit bearing, these should be nearly indestructible.
Models:
- Maxhit, External T47 BB for 24mm, DUB, and 30mm spindles. SRP: $179
- Maxhit Internal T47 BB for 24mm, DUB, and 30mm spindles. SPR: $179
