Argon 18 Nitrogen Disc TriStore Ultegra Di2 Build

The TriStore's build of the Argon 18 Nitrogen frame for disc provides you with a bike that's ready to tackle big climbs at a fast pace as well as shoot along the flats too. Argon 18's high-performance Monocoque frame that features on the Nitrogen has been created to give you a base that's lightweight as well as rigid and stiff so that you can climb fast and push the power through the pedals to build up your speed. The Nitrogen's frameset is fit for an aero profile and an aero design set up in order to optimise your speed whilst ensuring your comfort levels aren't comprised. This frameset includes a carbon seatpost to in-keep with the lightweight theme and ensure nothing is spared to keep your speed optimised. This Tristore build has been equipped with a full Ultegra Di2 8070 groupset that ensures you'll have swift and agile shifting that you can rely on when out you're riding or racing the roads. This build also features Argon 18's Monocoque fork that is designed for disc brakes to provide an 80% improvement in the lateral stiffness in comparison to the Nitrogen Pro. Fitted with hydraulic disc brakes, this Nitrogen build allows you superior control when riding, giving you reliable stopping power in all weather conditions. Using Argon 18's size-specific geometry, you're provided with a comfortable and ergonomic fit as each frame size is tailored specifically for its rider's needs. To provide you with reliable as well as agile road contact, this build features Roval C38 Carbon wheels and Specialized Turbo RapidAir Tubeless Tyres to keep your riding blissful. Argon 18 has used a 3D system on the Nitrogen that provides a choice of head-tube set-ups as you have the option of 3 different tube heights for each frame size. And finally, this TriStore build is equipped with a 3T ARX II Pro stem, 3T Superergo handlebars and Lizard Skin DSP 2.5 bar tape to provide you with a bike that has a smart finish.
