The Argon 18 Krypton carbon frameset lets designers adjust a greater number of parameters in pursuing their design goals and developing a versatile frame is very responsive, very stiff and it has a pretty unique sensation of forwardness. Now assembled with Shimano Ultegra/Dura Ace Mix. The seat and downtube have been given an aero profile; for this reason, a number of triathletes have chosen the Krypton for Multisport use. This frame and its matching Kr36 fork are designed to work as a unit. Both are made in Argon 18 exclusive CNC-machined molds using complementary materials, with the same performance criteria in mind.
