We’re big fans of the Krypton, so when Argon 18’s UK distributors unveiled the bike after a ‘multi-terrain’ makeover, we couldn’t wait to get our hands on it.

While tyre clearances have been increased to 32mm and disc brakes added to create the Krypton XRoad, the chassis has been built using the same principles as its road counterpart. Argon 18 designs its frames for stiffness through the drivetrain, down tube and head tube, while everything above them is intended to offer flex for comfort.

The XRoad also uses Argon 18’s ‘3D System’ of threaded head-tube-diameter spacers, which allow you to raise the bars without compromising front-end stiffness. Rather than relying on collars on the steerer tube, you pick one of the 3D System’s spacers (0, 15 and 25mm) and screw it directly into the head tube. Instead of simply plugging the gap between the headset and stem, this effectively lengthens the head tube while retaining most of its rigidity.
At the roadie end of the 'adventure' spectrum
On the road, the plump 28mm rubber, helped by the smooth Fulcrum R5 wheels and the slick operation of the Ultegra Di2 groupset, let you cover ground quickly. But the XRoad really comes into its own on damaged surfaces where it does a fantastic job of isolating you from jolts and bumps.
The expanding ‘adventure-road’ genre seems to be splitting into two camps: on one side you have road-biased gravel bikes, such as GT’s Grade and Specialized’s Diverge; on the other, are the more-hardcore off-road designs, such as the Cannondale Slate and Open U.P.
