Advanced Aero Storage for Road, Gravel, & Tri Bikes with Integrated Top Tube Bosses
The Speeedpack 483D is our compact advanced shape aero direct-mount top tube pack, designed to minimize the aero drag of your road, gravel, or triathlon bike. The Speedpack 483D is similar to the strap-mount Speedpack 483 except that the 483D is designed to bolt directly to your frame's integrated top tube storage bosses. Just like the Speedpack 483, the Speedpack 483D's full aero profile minimizes aero drag, even without hiding behind a stem. And reducing aero drag means more speed at a given power output. Like our other Speedpacks, the 483D's advanced computer-designed shape derived from a NACA airfoil maximizes the pack's aero advantage. The Speedpack 483D also has many unique features that further reduce drag, maintain on-bike stability, improve function, and still have outstanding durability.
