Here's what Flying Eagle have to say about the Horizon L80 Frames: 

The FlyingEagle HORIZON L80 frame offers the lowest ride in the market, (dependant on your boot, of course) enhancing control, power transfer and stability in order to deliver the ultimate skating experience. 

Low rider

The innovative design of the HORIZON places the front mounting block between the first and second wheel, creating the lowest possible ride for 4x80mm wheels. This geometry keeps you closer to the ground for superior balance, control, and powerful strides.

Progressive Flat setup

 A flat setup with a very subtle rockering that combined with the unique wheel arrangement and longer wheelbase offers more stability at top speeds than the standard 243 4x80mm configuration but superior manoeuvrability and acceleration compared to 4x90mm (theoretically). 

*Loco notes that this configuration will change the effective contact between wheels which would impact the frame effectiveness at turning compared to a 4x90mm despite any rockering. Equally, boot size will have an impact on this. The frame will respond very differently on a EU38 compared to a EU46. 

Asymmetrical

The asymmetrical wheel disposition offers a more natural skating experience with enhanced control and incredible power out of every stride, engineered specifically for city cruising and freeriding.

Custom fit flexibility

With sliding slot mounting, you can fine-tune frame position for your perfect stance. Each set also includes 3mm aluminum raising pads, ensuring maximum compatibility across boot models and foot sizes.

*This is referring to lateral adjustments, which is common amongst all aftermarket frames and allows you to account for any pronation and / or supination. 

One-piece construction

Precision-crafted from a single block of high-grade aluminum, the HORIZON’s extruded and CNC-machined construction guarantees uncompromising strength, durability, and efficiency - built to withstand the toughest urban environments without sacrificing speed or control.

*This is the standard production method for aftermarket inline skate frames.
