Helios Aero Geometry Data

Today we finalized the Helios Aero geometry data for all sizes. The head tube height was the last element that we had to confirm. The intent is to minimize the use of spacers while allowing a sufficiently low front end to maximize the aero benefits.

  • Thanks. Nice well-balanced race geometry. I like the longer headtubes.
    The geometry is not perfect for me, it never is due to my relative long legs.

  • +1 Seems very well balanced and a very versatile geometry.

    Ah, also good news that the image used to show the geometry is the black pattern (Aero Gold Pin) 😀
