Enduro Bearing 15x28x7mm 7902 ZS MAX
What Is It?
The Enduro 7902 ZS MAX bearing (15x28x7mm) is a high-performance sealed cartridge bearing commonly used in MTB headset systems (ZeroStack / ZS), suspension pivots, and frame linkage applications.
The “7902” is the bearing designation, while 15x28x7mm is the standard size. The ZS MAX version combines a headset-oriented application (ZS) with Enduro’s MAX design, which is optimized for high load and impact resistance rather than ultra-smooth spinning.
Key Features
- High-load sealed cartridge bearing
-
MAX design (full complement of balls, no cage) for maximum strength
- Standard 7902 bearing size: 15 x 28 x 7 mm
- Designed for MTB headset and frame load zones
- Rubber seals to protect against dirt, water, and contamination
- Pre-greased for durability and low maintenance
- Excellent resistance to shock and side loads
- Built for aggressive MTB riding conditions

Where It Is Used
- ZeroStack (ZS) MTB headset systems
- Suspension pivot assemblies
- Frame linkage systems
- Enduro and downhill MTB frames
- E-MTB headsets and high-load steering points
Who Is It Suitable For?
- Mountain bikers (trail, enduro, downhill)
- E-MTB riders
- Suspension and headset mechanics
- Riders servicing headset bearings or frame pivots
- Cyclists replacing worn or notchy headset bearings
- Riders in wet, muddy, high-impact terrain
Who Should Use It?
- Riders experiencing rough steering, play, or creaking headsets
- Mechanics rebuilding MTB headset assemblies
- Enduro/downhill riders under heavy front-end loads
- E-bike riders increasing stress on headset bearings
- Workshop technicians doing full bearing overhauls
- Anyone needing long-lasting headset durability
MAX vs Standard (Important)
-
MAX bearing: more balls → higher load capacity → better for pivots/headsets
-
Standard bearing: fewer balls → smoother rotation → better for hubs
