The latest generation of Principia’s trademark elliptical bottom bracket and head tube design. The increased diameter of the idsection of the tubes adds rigidity and strength without increasing weight. The ELLIPSE PROJECT gives you more efficient power transfer and more control when it counts.

Carbon seat posts are generally light and strong but can be fragile when fitted incorrectly. The pressure that the seat post is subjected to when tightening the seat clamp can be critical and even structurally fatal. Principia’s unique CARBON FRIENDLY SEAT TUBE gently distributes the pressure load over a larger area of the seat post. This clever design feature is safer for both you and your seat post.

Our extended INTEGRAL POST SYSTEM seat tube makes the necessary overlap between seat tube and seat post on traditional frames redundant. This allows us to remove excess material achieving an even better stiffness-to-weight ratio.
