DESCRIPTION
From the stage race breakaway to the final criterium lap, the all-new EnviLiv is made to be out front. We’ve redesigned our signature sprinter for optimized aerodynamic performance, greater stiffness-to-weight advantage, and maximum trophies.
Optimized Aerodynamic
In our pursuit of maximum power and efficiency, we analyze 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 an all-new Contact SL Aero cockpit, 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 new 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.

The sizing chart is a great place to start when picking your next bike but everyone will fit a bike a bit differently. Your torso, arm, and leg lengths all play into what size of bike you may need. Plus, there's your own personal preference.
We always recommend swinging by the shop and taking the bike that you're looking for a spin to see how it feels. If you're unable to come by, looking at the geometry of your current bike and comparing it is a good place to start. If you have any further questions, our customer service team is there to help.
