Entropia Road cycling saddle Structured Against Disorder

A hidden structure beneath what is visible.

Carbon Nanotubes were placed between the carbon-fiber laminae — at the interlaminar boundary, where delamination begins and shear forces concentrate. Higher stiffness, higher shear strength, no measurable weight added.

Four micrometres of carbon nanotubes, spread between every layer.

Disipa Interface

Energy enters the system. Heat leaves.

A precision elastomer sits between the carbon shell and the rails. Engineered to convert road vibration into thermal energy before it reaches the rider.

Most damping kits add mass and die quietly. Disipa Interface is a single layer tuned to the resonance of the laminate above it, absorbing the road chatter and allowing to ride for longer with more confort with no loss in power application.
