Offering the most aerodynamic, stiff and rigid frame available that doesn’t just conquer in headwinds, but in every other situation, the Parlee ESX Custom Road Bike is the perfect choice for the performance-obsessed cyclist who demands only the best equipment. Laced to the brim with Shimano Dura-Ace Di2 and HED Jet 4 Plus clincher wheels, you can head out with full confidence in your bike and its components.

Parlee ESX Custom Road Bike Large

The Parlee ESX Custom Road Bike towers over the opposition, not just in looks, but through sheer speed, comfort and power on the road, and the wind-tunnel data proves it. As the most radical design ever created by the designers over at Parlee, the ESX uses patented tube technology to cheat the wind, moving with it, not against it - making it one of a kind in the field of an all-around road bike.

The frame uses this technology they’ve aptly called ‘Recurve’, which uses a unique fluted tail shape to offer the ideal blend of low drag and high torsional stiffness - along with road-smoothing comfort that lacks in other aerodynamic bikes.

Designed to use 25-28mm tyres to its advantage, the frame smooths out the road ahead, offering comfort that’s otherwise unseen, and hidden cable routing enhancing the durability to keep you riding farther, faster and for longer.

We equipped this bike with the latest components to complement its sheer speed, and with a Fizik Cyrano R1 finishing kit to keep the front end rigid and dependable, you can be sure of that. Lay down the power either in and out of the saddle and you won’t feel any flex or loss of energy.

Shimano’s Dura-Ace 9010 braking system backs this up, allowing for powerful, reliable and predictable braking in a wind range of situations. Of course, what bike would be complete without Shimano Dura-Ace Di2 9070? Sitting at the top of the electronic shifting podium, this groupset shifts quickly and allows for minute changes to truly perfect your personalisation.

HED Jet 4 Plus clincher wheels and Bontrager R4 320 Hard Case Lite tyres finish off the build beautifully, giving you supreme puncture resistance and a strong and durable base for you to lay down the watts.


  • Aerodynamically optimised Parlee frameset that cuts through the wind, allowing you to remain efficient and powerful without exerting any extra power
  • Shimano Dura-Ace 9010/9070 groupset is reliable for the ultimate in shifting speed and braking power
  • HED Jet 4 Plus Clincher wheelset furthers aerodynamic ability

Please note:

When purchasing this frame, the components are eligible to be changed and/or upgraded to your liking. Please contact us if you require this option.
