2017 Argon 18 Nitrogen Pro

If you are looking for a bike that focuses on aerodynamics and offers stable, predictable handling, then the Argon 18 Nitrogen Pro will be a great option to consider buying. Good enough for the pros at the Tour de France, but accessible and comfortable for those of us who just love a great looking, lightweight bike to tackle our local roads.

Even if you are not swayed by the fact that Argon 18 sponsor some of the best cyclists in the world, you can nevertheless feel secure in the fact that these bikes are rigorously tested in labs and then in real world races, so that their reliability and utility are marked in equal measure. So things like the aerodynamics can be modeled and then tested, resulting in developments like Argon 18’s new carbon monocoque AHB5000 aero handlebar system that offers up to a 30% aero improvement over standard round bars. And don’t think that weight was sacrificed to get that level of aerodynamic advantage since the Nitrogen Pro weighs in around the 830 gram mark, which is very light for an aero bike no matter how you cut it.

Things like the hidden front and rear brakes go a long way to reducing the amount of drag and air disturbance that will result from those typically un-aero areas. The braking power with the these specially designed brakes will also give you the sort of confidence to push your speed. That confidence also comes from the supremely stable handling the Nitrogen Pro offers. Some aero bikes, especially those born out of WorldTour racing, can feel very jittery at high speeds. But this is a bike that will be quick in its accelerations without feeling unsteady in high speed situations or descents. The aggressive geometry hints at the pro pedigree, but you don’t have to worry about it being uncompromisingly uncomfortable. On the contrary, Argon 18 have incorporated their Press-fit 3D System to allow for a wide degree of flexibility in how you set up your front end. It allows you to adjust the front end stack according to your needs – 0mm if you rather like a steeper drop to the bars, 15mm if you like to stay fairly low, but want to give your back a break, and 25mm if you really do like the added comfort a higher stack can offer you, even when you are hammering your way through the Saturday criterium course. And on top of that, the ASP-5100 seat post is lighter, aero and offers a wide degree of adjustability as well.

In fact, this would be a great bike to go with especially if you have any thoughts of testing your fitness in a triathlon, the Nitrogen Pro could certainly be a reasonable option if you don’t feel like investing in a full-up tri bike. And since it is UCI legal, you can thrash it in any of the UCI sanctioned USA Cycling events around the country. The Argon 18 Nitrogen Pro comes in five sizes and can be bought as a frame to be built up from scratch, or you can buy one of the prebuilt options available and hit the roads hassle free. In either case, you will be happy to enjoy one the high performance and relative comfort that an expertly made aerodynamic bike like the Nitrogen Pro can offer.
