Enduro Bearing 15x28x7mm ZS MAX
What Is It?
The Enduro Bearing 15x28x7mm ZS MAX is a high-load sealed cartridge bicycle bearing typically used in MTB headset systems (ZeroStack / semi-integrated), suspension pivots, and frame linkage applications.
The “ZS” designation refers to ZeroStack headset standards, meaning this bearing is commonly found in headset upper or lower assemblies depending on frame design.
The MAX version is built for maximum durability under load, using a full complement of balls (no cage) to increase strength and resistance to impact forces.

Where It Is Used
- MTB ZeroStack (ZS) headset systems
- Suspension pivot assemblies
- Frame linkage systems
- E-MTB frames under heavy loads
- High-stress steering and frame interfaces
Who Is It Suitable For?
- Mountain bikers (trail, enduro, downhill)
- E-MTB riders
- Suspension and headset mechanics
- Riders servicing headset bearings or pivot systems
- Cyclists replacing worn or notchy headset bearings
- Riders in aggressive, wet, or muddy conditions
Who Should Use It?
- Riders with loose, rough, or creaking headset movement
- Mechanics doing headset rebuilds or full frame servicing
- Enduro/downhill riders under high steering and impact loads
- E-bike riders increasing stress on headset systems
- Workshop technicians performing bearing replacements
- Anyone needing long-lasting headset durability
Why MAX Matters Here
- More internal balls = higher load distribution
- Better resistance to shock and compression forces
- Ideal for load-heavy, low-rotation applications like headsets and pivots
- Longer lifespan in harsh MTB environments
