The EnviLiv Advanced SL is designed and optimised for aerodynamic performance making it the official aero road bike of Liv AlUla Jayco WorldTeam. From stage race breakaways to the final criterium lap the EnviLiv is made to be out front. 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 EnviLiv features truncated ellipse airfoil tube shapes and the Liv Contact SLR Aero 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 new EnviLiv has found the sweetest spot with an Advanced SL-grade composite frameset. We use Continuous Fibre Technology to add strength without adding weight Carbon Nanotube Technology resin to improve impact resistance and Fusion Process for lighter stronger frame junctions. So you can accelerate faster away from the pack. 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 SL Composite Technology Liv’s Professional Grade raw carbon material is woven in our own composite factory using our most advanced engineering and construction methods including: Continuous Fiber Technology to add strength while reducing weight; Carbon Nanotube Technology resin to improve impact resistance; and Fusion Process for lighter stronger frame junctions. 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. RideSense Ready This means the frame comes prepared to accept the RideSense sensor and accompanying hardware. Tubeless System Engineered with proprietary Dynamic Balanced Lacing technology this tubeless ready composite WheelSystem delivers superior efficiency pinpoint control and comfort. 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. Vector SLR Seatpost Using more continuous carbon fibers and titanium bolts the Langma’s first fully-carbon seatpost is lightweight aero and easily adjustable.
