2021 Argon 18 Krypton CF, Size M is a refined carbon endurance road bike designed to balance performance, comfort, and long-distance efficiency. Built around Argon 18’s Krypton CF carbon frame and fork, it delivers a smooth, stable ride while maintaining a lively and responsive feel on climbs and accelerations. The bike is equipped with a Shimano Ultegra Di2 2x11 drivetrain, offering precise, reliable electronic shifting, paired with Ultegra brakes for confident stopping power. Rolling on HED wheels with ENVE SES 31C tires, this setup provides excellent comfort, grip, and efficiency, making it ideal for longer rides and rougher pavement. With a weight of approximately 17.9 lb and a fit range best suited for riders around 5’8”–6’0”, this bike has logged 1,700–2,000 miles and is in good pre-owned condition, showing only minor cosmetic marks consistent with normal use. It has been well maintained and is fully ready to ride.


Why we love it

We love the Argon 18 Krypton CF because it’s a true all-day road bike that doesn’t sacrifice performance for comfort. The endurance-focused geometry, quality carbon layup, and wider tire clearance make long rides smoother and less fatiguing, while Ultegra Di2 keeps shifting crisp and effortless. It’s a perfect choice for riders who want a fast, elegant road bike that excels on long miles, mixed road surfaces, and real-world riding conditions.

Pre - Owned, good shape. Ready for rides. As all used bikes it has some small scratches here and there but nothing major.
