Argon 18 announced an all-new Krypton Pro endurance road bike for 2020. The bike is aimed at endurance cyclists wanting a comfortable ride capable of tackling Paris-Roubaix cobbles in the hands of the Astana Pro Team it currently sponsors. With disc brakes, integrated cabling, and accommodations for mechanical and electronic shifting, its got all the bells and whistles.
The Krypton used to be a purely race purpose bike but has since morphed into an endurance bike. With this new model, Argon 18 has focused on optimizing the carbon fiber layup, moving towards increased integration and adding more aerodynamics.
With the new carbon layup, Argon says that it’s aiming for an ideal blend of weight, comfort, and stiffness for long mileage riders. The frame weighs in at just 870 grams (medium, painted frame), with improved vibration damping over previous models.
“By studying endurance-specific load cases, we oriented material where needed to maximize vibration dampening, without losing efficiency in power transmission. This let us eliminate excess weight where not required,” says Martin Faubert, VP Product at Argon 18. “We can now offer a lighter frame than the Krypton GF, but with all the same endurance characteristics which we’ve been hearing about from our riders.”
Integration and clean cockpits are big with road bikes right now. Argon 18 has developed a fully integrated cable system using a proprietary stem and steerer tube to get rid of external cables completely. There’s full compatibility with all current groupsets, using a down tube port to accommodate mechanical and electronic cabling.
The system still provides a range of fit adjustment, unlike much of the competition. Six stem lengths from 70 to 120mm are available and the company’s 3D+ system lets you adjust the stack by swapping out integrated head tube extensions, with a choice of three stack heights.
Argon’s 3D+ system extends the head tube, with three positions available. The result is a claimed 5% increase in rigidity at 15mm of stack, or 11% at 30mm (compared to traditional spacers).
While the stock stem looks clean and integrated, it accepts all standard 31.8mm handlebars – and Argon 18 even says that it allows for a 2cm adjustment range of stack and reach without having to bleed the brakes.
While this is an endurance-focused bike, Argon took cues from their Nitrogen Disc model to improve its aero performance:
“Aero still matters on an endurance bike. We didn’t add a single feature to this model which didn’t perform optimally across all our priority performance indicators, including aero. For example, our hidden cables offer a 2.5w savings at 300W.”
Tire clearance looks good and I do like that they considered cockpit position changes without changing hose length. Too many bikes with zero flexibility these days. The rubber stem wrap is certainly innovative.
One build kit will be offered for now (Ultegra Di2 groupset with HED carbon wheels) for $7,500 complete.
