Speed, low weight, fit and ride quality: with the Nitrogen Pro you no longer have to choose. It is Argon 18's flagship aero road platform, built to deliver in real-world race conditions.
Everything from the flow-optimised headtube to the dropped seat stays is shaped to cut drag, while the ATTEN CHB-01 cockpit and Pro Level Layup carbon keep the bike stiff, light and precise.
Highlights
- Pro Level Layup carbon frame
- Flow-optimised headtube and wider, deeper fork
- ATTEN CHB-01 aero handlebar and integrated cockpit
- Integrated aero bottle cages
- Horizontal, dropped seat stays inspired by the Electron Pro TKO and E119
- SRAM Red AXS, Shimano Dura-Ace Di2 and Ultegra Di2 builds
