Argon 18 Gallium Pro Disc Ultegra R8070 Di2 Road Bike 2019
The Argon 18 Gallium Pro Disc R8070 Di2 Road Bike is a thoroughbred racer, built for going fast. Featuring Argon 18's pro-level carbon frameset, this bike boasts supremely assured handling and a super-stiff platform for your efforts, all whilst remaining extremely lightweight. The use of thru-axles further increases this bike's stiffness, helping to ensure that every watt is transmitted to the road. The Ultegra disc brakes guarantee assured braking power and responsive modulation, whatever the weather conditions.
Gear shifting is also provided by Shimano's excellent Ultegra Di2 system, lending the bike the crisp and dependable gear shifting that electronic groupsets are renowned for. The Ultegra cranks, in a 52/36 tooth option and combined with an 11-28 cassette, are reassuringly stiff and primed for riding fast. The wheelset, Vision's TriMax 30 Disc, is a dependable and lightweight option that enhances this bike's climbing credentials, whilst the Vittoria Open Corsa CX tyres are fast-rolling on the flat and assured in the corners.
The bike's geometry follows that of Argon 18's pro-team builds - low and racy with a tight wheelbase for optimum aerodynamics and flighty, eager handling. The inclusion of an inlaid chainsuck protector gives this bike a touch of real-world durability, helping protect it against the rigours of hard riding. Argon 18's exclusive 3D headset system, meanwhile, offers the rider great scope for adjustment, ensuring that your bike fits perfectly no matter your physiological requirements. This bike is topped off with Argon 18's own carbon seatpost and FSA's K-Force carbon handlebars - two premium additions that add a touch of compliance along with their low weight. The Gallium Pro Disc is a premium, pro-level machine, ready to race straight from the box - you won't be disappointed.
