A fast and lively feel but you’ll have to accept a bit more discomfort in return for the speed
Light
Stiff
Holds speed well
Superb precise handling
Not quite as forgiving as others that can match its speed

Argon18 Nitrogen is a head-down, ride hard in a straight line kind of bike with notably good aero brakes

May 2016 · William Tracy
For crits, you want power transfer and confident handling, and Argon 18's Nitrogen has plenty of both.

Feb 2016 · Robin Wilmott
Useful positional tweaks help the Nitrogen Pro fit like a glove and ride like the wind. Buy if you want a great-looking aero bike with clean lines and pro-level performance
