The ESX has a patent-pending tube shape called Recurve that has superior aerodynamics without the structural tradeoffs inherent in traditional airfoil shapes. The company said the shape achieves an excellent range of performance across yaw angles, which translates to real world watt savings without a harsh ride or heavy, dead feel.
The bike also features Parlee's third generation Flex-Fit geometry, which creates two stack-and-reach geometries for each of five sizes by having an interchangeable spacer system, creating a race and endurance fit on the same bike.
The bike is available for pre-order now with first deliveries scheduled for December. Custom paint will be an option starting in January.
Like all Parlee frames, the ESX is sold exclusively through IBDs. The frame set assembly is $5,400 MSRP, with complete bikes starting at $6,500.
