Argon 18 Nitrogen Pro Ultegra R8050 Di2 Road Bike 2018

Featuring a frameset direct from the pro peloton, the Nitrogen Pro Ultegra R8050 Di2 Road Bike represents a fantastic choice for those looking to take their riding to the next level. The Nitrogen Pro is built around Argon 18's top-of-the-range aero frame, offering a stiff, lightweight platform that offers superb power transfer as well as assured and dependable handling.

The handlebar and frame tube profiles, meanwhile, are refined for aerodynamic performance, and the addition of wind-cheating TRP brakes hidden behind the fork and seat stays help to make this a bike that cuts through the air with ease. The lightweight Vision wheelset benefits from bladed spokes and the frame geometry is aggressive and low, further adding to this bike's impeccable aero credentials. The wheels themselves are shod with Vittoria's fast-rolling Open Corsa CX tyres in a racy 25mm width.

The Shimano Ultegra Di2 groupset provides flawlessly reliable electronic shifting, while the crankset provides the stiff and efficient power transfer that we've come to expect from this excellent groupset option. The Nitrogen Pro also boasts some technological innovations exclusive to Argon 18 - the 3D system, for example, is a unique headset unit designed to offer three different headtube heights to cater for a variety of rider physiologies. Similarly, the Argon Fit System geometry ensures that every size option has been optimised to best serve the needs of that specific rider, rather than apply uniform tube profiles en masse across the range. The combination of the two technologies means that the Nitrogen Pro can be finely tuned to any rider's requirements without compromising the bike's pro-level perfomance.

The Nitrogen Pro is rounded out with a premium Prologo saddle and an aero carbon seatpost, additions that help with damping roadbuzz to make this bike as comfortable as it is fast.
