The 2016 Storck Aerfast Pro Road Bike Frameset is built with one thing in mind: speed. With aerodynamic design features and Storck's trademark stiffness and impeccable handling, this frameset is built to fly to the finish line. Made from light, stiff unidirectional carbon fiber, the Aerfast Pro features Storck's Sectional Aerodynamic Shaping, which means the down tube profile is narrower and more droplet like at the middle compared to the top and bottom sections. This reduces frontal surface area, which reduces drag, all without impacting frame stiffness or handling. A concealed seat clamp keeps excess bolts out of the wind, and just plain looks good with a super clean transition from seat tube to seat post. At the rear, an integrated brake tucks in behind the bottom bracket to provide stopping power without catching any wind. The rear triangle on the Aerfast Pro is something of a revelation, featuring rear facing dropouts which allow adjustability to customize the space between the wheel and seat tube based on the type of tires you prefer. This option means you'll maintain ride characteristics and snappy handling regardless of the tire. Storck also incorporates proportional tubing to provide a consistent level of aerodynamics and responsiveness across the size range. For an extra dose of stiffness, Storck opts for a beefy BB86 bottom bracket standard that will solidly transfer every bit of power to the drivetrain without any watt sucking lateral movement. At the front, an integrated, tapered headset and Airfast Pro carbon fiber fork combine for stiff, responsive handling to keep things smoothly in control. Storck caps off the 2016 Storck Aerfast Pro Road Bike Frameset with internal cable routing compatible with both mechanical and electronic shifting systems for clean lines and an extra shot of aerodynamic advantage regardless of setup.
