From the stage race breakaway to the final criterium lap the EnviLiv is made to be out front. We’ve designed our signature sprinter for optimised aerodynamic performance greater stiffness-to-weight advantage and maximum trophies. Key Performance Factors Optimised Aerodynamics In our pursuit of maximum power and efficiency we analyse how the bike and rider experience airflow at every speed and direction both on the computer and in the wind tunnel. The new EnviLiv features truncated ellipse airfoil tube shapes and the Liv Contact SL handlebar with flattened tops and deeper drops for reduced drag and added control and better overall aero performance. Sprinting Efficiency Aerodynamics are affected by many factors two of them often seen as mutually exclusive: stiffness and weight. But the EnviLiv has found the sweet spot with a new Advanced-grade composite frame and fork—resulting in 292 grams of weight savings over the previous generation. Seamless Integration When every second matters so does every detail. So we developed a way to route cables through the handlebar stem and frame which improves aero performance and also makes it easier to disassemble your bike for travel and maintenance. Two aerodynamic water bottle cages flawlessly integrate with the seat tube and down tube further reducing drag. Advanced Composite Technology Liv’s High-Performance Grade raw carbon material is used to produce this frameset in our own composite factory. Using state-of-the-art materials and manufacturing techniques Liv’s Advanced-Grade Composite frames are designed to offer light weight and stiffness with optimal compliance. AeroSystem Shaping Technology Tubing shapes engineered using computational fluid dynamics CFD and wind-tunnel data to optimize each tube shape for superior aerodynamic performance. OverDrive Aero Found inside the head tube of the all-new EnviLiv range the D-shaped fork steerer tube and corresponding spacers provide an extremely aerodynamic easier to service system of internally routed brake and derailleur cables. PowerCore A massively oversized bottom-bracket/chainstay area features a fully integrated 86-millimeter wide bottom-bracket design 92-millimeterwide for off-road bikes. Asymmetric chainstays provide additional stiffness on the driveside and stability on the non-driveside. Tubeless System Engineered with proprietary Dynamic Balanced Lacing technology this tubeless ready composite WheelSystem delivers superior efficiency pinpoint control and comfort. Vector Seatpost This full-composite lightweight and highly aerodynamic seatpost is engineered specifically for performance road riding.
