ELLIPSE PROJECT
The latest generation of Principia’s trademark elliptical bottom bracket and head tube design. The increased diameter of the midsection 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 FRENDLY SEAT TUBE
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. |

SX GEOMETRY
Principia’s SX GEOMETRY adapts the slope of the top tube to the individual frame sizes adding more slope to the smaller frame sizes and less slope to the larger frame sizes. This means that tall riders do not have to use long seat posts that are structurally weak and unaesthetical. |

PRINCIPIA MAGNUM ALUMINIUM
The latest generation of Principia’s acclaimed aluminium technology with conified and triple butted aluminium tubing; made from a newly developed alloy with improved comfort properties that set a completely new standard for aluminium frame tubing. After the TIG welding the PRINCIPIA MAGNUM ALUMINIUM frames go through an advanced multi-stage heat treatment process for maximum strength and stiffness. |
