Argon 18 Nitrogen Disc Tristore Ultegra Build

This Tristore build is created using Argon 18's Nitrogen disc frameset to give you a bike that'll keep you going fast along the flats as well as shooting up those hills and long climbs. The Argon 18 Nitrogen high-performance Monocoque frame is designed to be lightweight as well as stiff and rigid in order to provide you with a great base for pushing the power. Argon 18 created this frame to fit an aero profile as well as an aero design without compromising on your comfort levels to ensure this bike isn't just fast but it also helps keep you going strong over a longer duration in the saddle. The Nitrogen also incorporates Argon 18's Monocoque fork for disc which allows for an 80% overall improvement to the lateral stiffness when compared to the Nitrogen Pro. The Tristore build features a fully integrated Ultegra 8020 groupset that provides you with smooth and reliable shifting when riding as well as when racing. The hydraulic disc brakes also ensure you stay in full control, providing you with strong stopping power even when the weathers damp. The Nitrogen frame uses size-specific geometry for an ergonomic fit that's also comfortable for you. The seatpost featured on the Nitrogen is carbon to keep the frameset lightweight. The Tristore build includes Roval C38 Carbon Wheels along with Specialized Turbo RapidAir Tubeless Tyres to make for an agile ride. The Nitrogen also uses a 3D system that allows for a variety of set-ups as the head tube can be set at 3 different tube heights for each frame size whilst ensuring no compromises are made to the frame's rigidity. Finally, the Tristore has fitted this bike with 3T Superergo handlebars, a 3T ARX II Pro stem and Lizard Skins DSP 2.5 bar tape for a smart finish.
