Built around the details.

The details that make the Eclipse One faster, shown close up.

Aero Optimised

CFD and wind tunnel tested. Truncated airfoil tube shapes and a streamlined front profile reduce drag and turbulence, so you hold higher speeds for less effort.

Fit System

Adjust aero bar height the way you would a seatpost. The aero bar also moves forward and back across two points, so you can dial in your exact race position.

Frame

High-modulus carbon fibre delivers an exceptional stiffness-to-weight ratio - every watt you generate goes into forward motion, with precise handling through technical sections.

Finish

A sleek matte and gloss black finish with minimalist branding and clean lines - built to look as considered as it rides.

Geometry

All measurements in millimetres unless noted. Angles in degrees. Scrolls horizontally on smaller screens — size stays in view.
