Argon 18 Nitrogen Ultegra R8050 Di2 Road Bike 2018

Argon 18's Nitrogen family is renowned for superior aerodynamic performance - and the Nitrogen Ultegra R8050 Di2 Road Bike is no different. Topped only by the Nitrogen Pro in Argon's line-up, this is a thoroughbred aero machine, built around a lightweight carbon frame that has been developed specifically for cutting through the air. This bike boasts Argon's 3D headset unit which, coupled with the fully internal cable routing, helps with aerodynamic performance and lends the bike a smooth, clean aesthetic. The Nitrogen's brake calipers are carefully placed behind the seat stays and chain stays in order to hide them from the wind, a further boon to the bike's already outstanding aero credentials.

Shifting is taken care of by Shimano's Ultegra Di2 groupset, lending the bike the flawless and precise gear shifting that electronic groupsets are renowned for. Vision's TriMax 30 wheelset is a solid and dependable option which, paired with the Vittoria Rubino tyres, will keep you rolling at speed all day long. The package is rounded out with a carbon aero seatpost and a comfy saddle from Italian manufacturers Prologo.
