What Our Gearhead® Experts Are Saying:
"I’ve laced the HB-M9210-B into multiple wheelsets, and it's everything you'd expect from XTR—smooth, quiet, and dependable. The new cartridge bearings spin effortlessly, and it’s super easy to dial in preload. Definitely my go-to for any high-performance XC or trail build."
When we’re building a wheelset that needs to be fast, smooth, and totally reliable, the Shimano XTR HB-M9210-B Front Hub is at the top of our list. Designed around Boost spacing (110x15mm), it’s built to keep our front end stiff and responsive, whether we’re charging rough descents or hammering through an XC course.
The new stainless steel cartridge bearings paired with optimized seals and preload adjustability deliver ultra-smooth rotation and long-lasting performance with minimal maintenance.
