Description

2D Floating Technology

The patented floating rivet structure on the back of the rotor is the key to the 2D floating technology, giving the outer disc a large one-way movement space.

Floating Outer Disc

When the rotor meets asymmetric clamping of the brake pads during braking, the floating structure activates and the outer disc adjusts itself to a proper position, so both sides of the disc withstand the same amount of wear.

Better Performance

Beyond maintaining disc strength, heat deformation from thermal build-up and abnormal noise from frame resonance are both reduced during braking. This makes the rotor suitable for e-bike use and gives it a longer service life.

QUESTIONS?

What is 2D floating technology on the AB-04 rotor?
The AB-04 uses a patented floating rivet structure that lets the outer disc move and self-align under braking. This spreads wear evenly across both faces, reduces heat deformation and cuts brake noise, and makes the rotor suitable for e-bikes.
What sizes and mount does the AB-04 come in?
The AB-04 is a two-piece Center Lock rotor, available in 180mm (188g) and 203mm (228g). Please confirm the correct rotor size and that your hub is Center Lock before ordering.
What is the AB-04 rotor made of?
The braking surface is stainless steel (SUS 410) for durability and consistent braking. The spider (centre) is forged aluminium alloy, which adds rigidity while keeping weight down.
Is the AB-04 rotor suitable for e-bikes?
Yes. The 2D floating structure reduces heat deformation and frame resonance noise under sustained braking, so the AB-04 is rated for e-bike use and offers a longer service life.
