Maxhit 440C Stainless Steel BSA24 Bottom Bracket Kit – Built for the Long Haul, Forged for Precision

Meet the bottom bracket that redefines durability: the Maxhit BSA24 Bottom Bracket Kit, forged entirely from 440C stainless steel and purpose-built for riders who push their gear to the edge—day in and day out.

This is not your average bottom bracket. It's a powerhouse in a compact package, precision-engineered for threaded BSA frames and 24mm spindle cranksets like Shimano Hollowtech II. From its industrial-strength materials to its meticulous design, everything about the Maxhit screams longevity and performance.

At the core of this beast lie 440C stainless steel bearings—a material renowned for its unmatched balance of hardness, corrosion resistance, and fatigue strength. These aren’t hybrid bearings with compromises; they’re full-metal warriors designed to spin smooth, resist rust, and shrug off grime, water, and whatever punishment the trail throws at you. Expect a bottom bracket that won't just survive—it will thrive through seasons of riding.

But what truly sets the Maxhit apart is its one-piece integrated architecture. Rather than combining cups and races like most traditional setups, Maxhit machines everything as a single unit. The result? Fewer weak points, tighter tolerances, and an unrivaled stiffness-to-weight ratio. It threads in with precision and holds like a vice—no creaks, no loosening, just rock-solid performance.

With its sleek black finish, this bottom bracket doesn't just perform—it looks every bit as refined as it rides. And thanks to the BSA threading, you get the peace of mind that comes from a tried-and-tested standard: easy installation, no pressing tools, and minimal fuss during service.

Whether you're crushing long climbs, hammering out sprint intervals, or grinding through gritty winter miles, the Maxhit 440C BSA24 is the kind of component that quietly does its job—until you realize it’s been years and it’s still spinning like day one.
