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. |

DESIGN 2 SIZE
Traditional frame design uses tubing with identical diameters and wall thicknesses for all frame sizes. Either this makes the smaller frame sizes too heavy or the larger frame sizes insufficiently strong and stiff. Principia’s DESIGN 2 SIZE technology optimizes the tubing specifications for the individual frame sizes ensuring optimum riding characteristics for riders of all sizes. |

XC GEOMETRY
This is the mountainbike frame geometry that best allows you to utilize all your power on the climbs without compromising stability and control on tricky descends. The XC GEOMETRY carries on the acclaimed Principia handling properties that gives you superior speed resources – whether you ride to win or just for fun. |

WEAVED PRINCIPIA CARBON
Principia’s proprietary carbon technology combines first class carbon filaments with a newly developed lay-up technique. WPC technology allows maximum control of the direction of the fibres enabling us to carefully fine-tune key properties such as stiffness, strength and comfort. WEAVED PRINCIPIA CARBON exclusively uses Mitsubishi filaments with tensile strenghts ranging from 12 (C12T) to 40 (C40T) tonnes per square centimetre. |

INTEGRATED SHIFTING PRECISION
Imagine a replaceable rear derailleur hanger that allows you to shift gears with the precision and reliability of a fixed non-replaceable rear derailleur hanger. The INTEGRATED SHIFTING PRECISION derailleur hanger is a unique Principia feature which combines the precision and rigidity of a fixed derailleur mount dropout with replaceability. INTEGRATED SHIFTING PRECISION is featured on all Principia models. |

CARBON FRIENDLY 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. |

PRINCIPIA MONOCOQUE TRIANGLE
With the newly developed mountainbike-specific carbon technology, Principia Monocoque Triangle, the rear triangle of the frame is a true monocoque construction made of 100% carbon fibre. Based on the proprietary Weaved Principia Carbon technology PMT sets new standards for weight, stiffness and strenght. |
