Advanced Aero Storage for Road, Gravel, & Tri Bikes with Direct Mount Top Tube Bosses

The Speedpack 483D is similar to the Speedpack 483 except, instead of mounting with our advanced strap system, the 483D is designed to bolt directly to the integrated top tube storage bosses on the Cervelo P5, new P2/P3, Trek Speed Concept series, and many others. Like the Speedpack 483, the Speedpack 483D's full aero profile minimizes aero drag, even without hiding behind a conventional stem. And minimizing drag means more speed at a given power output.

To maximize the aero advantages of the Speedpack 483D, it has the same computer-designed true NACA airfoil shape as the Speedpack 483. And it has many of the same unique features that reduce drag, improve on-bike stability, ease usability, and maintain high durability.

The Bottom Line:  The streamlined Speedpack 483D will securely and conveniently carry the race and training gear you need on your advanced triathlon bike, while minimizing drag and helping you ride faster.
