First introduced in 2015, the Nitrogen set itself apart from other Aero bikes by its versatility, its impeccable handling and stiffness. The Nirogen Pro followed in 2016 turning all of the original bike’s qualities up a notch. No wonder it was so well received by both critics and pro racers.
Times change fast and the 2019 version of the Nitrogen has no problem keeping up with them…
It’s show time. The 2019 Nitrogen Disc is one lean mean racing machine.
Built for those who not only want to lead the pack in performance, but also with a sleek, aerodynamic, feature-packed, racing bike that makes a statement wherever it goes. Throw in the braking power of disc brakes and you get a bike that says: Move the heck over, Nitrogen is here.
The weighting game is over
At 948g for a medium size frame (painted with no small parts), the new Nitrogen Disc is the true embodiment of a lightweight aero disc frame. It may be a little heavier (65g) than the Nitrogen Pro was but it is significantly lighter than the original Nitrogen and most other aero disc bikes offered on the market today.
THe Nitrogen Disc clearly demonstrates that a bike frame can be aero, sport disc brakes and remain as light as a great road bike should be.
Some will wonder why we decided to offer the Nitrogen in a disc only version for 2019. Here is why:
The improved fork shape and carbon lay-up along with the use of a DT swiss type 12mm Thru-Axle bring an 80% increase in ,lateral stiffness vs the 2018 Nitrogen Pro with the same comfort level making the bike more responsive in sprints and climbs while eliminating chances of the front brake pads rubbing on the wheel
It’s the way of the future. Full Stop.
Disc brake aero penalty is imperceptible.
Less than 2W at 45km/h and 0° yaw and no effect at yaws higher than 5°. This is due in part to an improvement of the fork legs profile to obtain a better flow. The removal of rim brakes also brings better flow around the junction between fork and downtube.
The use of disc brakes enables better tire clearance.
The new Nitrogen Disc frame is now compatible with 28C tires for better comfort.
These plus the fact that disc brakes are more effective than rim brakes in all weather conditions made it an easy choice for us to make. So, here it is, the Nitrogen Disc a thoroughly modern bike with an eye to the future.
As explained earlier, weight is no longer an issue in high performance disc brake aero bikes.
• HIGH PERFORMANCE CARBON MONOCOQUE FRAME
Very stiff yet light, it offers all the advantages of disc brakes with no weight compromise.
• DT SWISS TYPE 12MM THRU-AXLE
Clean, simple, light and sturdy
• IMPECCABLE HANDLING
Superior downhill stability and handling
• 3D SYSTEM
Extends positioning flexibility by offering 3 head tube heights for every frame size without sacrificing any rigidity; system preserves 5% and 11% more incremental frontal rigidity vs. standard spacers when the handlebar is set at 15mm and 25mm respectively
• AERO CARBON SEAT POST
Light and easily adjustable
• REPLACEABLE REAR DERAILLEUR HANGER
Optional direct mount hanger supplied
• FLAT-MOUNT DISC BRAKES
Ensuring better braking in all conditions
• UP TO 28C (30MM) MTIRE CLEARANCE
For maximum comfort and compatibility
An Argon 18 Race geometry Through and through.
The 2019 Nitrogen Disc has essentially retained the same geometry that proved a winning formula for the previous generation Nitrogens and all of our race bikes for that matter.
Our only real modification to that geometry was to make the chainstays a little longer as we do on all our disc brake road bikes.
Disc brake wheel hubs are wider than their rim brake counterparts making this modification mandatory to ensure the best possible chain line and reduce “cross chaining” possibilities.
