The Krypton is an all-road endurance bike designed for long pavement rides, rough roads, light gravel, fast commuting, fondo riding, and riders who want one road bike that stays comfortable and efficient across changing surfaces. How much tire clearance does the Krypton have? The Krypton is listed with clearance for up to 40c tires, or 43mm measured clearance, which gives riders the option to run fast 32mm road tires or wider all-road tires for mixed surfaces. Does the Krypton have hidden storage? Yes. The Krypton platform includes a downtube storage compartment and Storage Optimization System so riders can carry tools and essentials cleanly inside the frame. Is the Krypton more of a road bike or gravel bike? The Krypton is an all-road bike. It is faster and more road-oriented than a dedicated gravel bike, but it has more tire clearance, comfort, and surface versatility than a pure road race bike. Which Krypton model should I choose? Choose SRAM Force AXS for the highest SRAM build, Shimano Ultegra Di2 for premium Shimano performance, SRAM Rival AXS E1 for wireless value, and Shimano 105 Di2 for the most accessible electronic-shifting Krypton.
