Why ROCKERON?

Adjustable by design

ROCKERON uses a protected internal retention geometry that securely holds the balls under load.
This design is the core of ROCKERON and enables safe swapping between different ball stiffness levels without slippage or instability.

Ball stiffness options:

Yellow – Hard: Stable, efficient, race-like feel

Green – Medium: Balanced movement for everyday riding

Orange – Soft: Maximum comfort and freedom on long sessions

---

Natural movement, real comfort

The controlled side-to-side motion reduces saddle pressure, relieves stress on hips and lower back, and delivers a more road-like riding experience indoors.

---

Minimalist alternative to rocker plates

No large platforms

No heavy frames

Just a compact, clean solution focused on function
