FAQ
What is the difference between the version 4.0 and the version 3.0
The V4 brings significant improvements over the V3 for enhanced stability, durability, and user experience:
Reduced Gaps and Tolerances: We've minimized the gaps between components, creating a tighter connection for superior stability and equal tension on both legs.
Strengthened Weight Arm Junction and Balanced Weight Horn Design: The connection between the weight arm and frame is reinforced for enhanced durability and lifetime alignment stability. The weight horn is now a dual-sided design, effectively preventing weight plate slippage during use.
Upgraded Aluminum Pulley: The pulley has been upgraded to a durable aluminum one, ensuring lifetime longevity.
More Flexible Adjustment: The V4 features 9 adjustment positions on the cam (compared to 7 on the V3). The foot roller can now be freely rotated to adjust its orientation inward or outward and then fixed with a peg for personalized comfort.
Fit for Taller Users: We've lengthened the movement arm and foot roller frame to ensure the foot roller pad comfortably conforms to the ankles of taller individuals.
Enlarged Base: The rectangular base is enlarged with extended rear feet, significantly increasing overall stability.
