Advanced Aero Storage for Triathlon & TT Bikes with low-profile strap system

The Speedpack 483 is our advanced aero top tube-mounted storage pack. The 483's advanced highly versatile mounting system allows the 483 to fit nearly any bike on the road. This means that the Speedpack 483 is compatible with many of the latest triathlon superbikes, including those with integrated stem and aerobar systems. The Speedpack 483's special low-profile strap system allows the pack to mount securely to your top tube with ZERO sliding and without attaching to a stem or steerer tube. The 483's full aero profile minimizes aero drag, even without hiding behind a conventional stem. And reducing drag means more speed at a given power output.

The Speedpack 483 is also the perfect choice if your bike has top tube entry aero cabling (shift and/or brake cables that enter the top tube vertically behind the stem). The Speedpack 483 can mount nearly anywhere on your top tube and its advanced mounting system means that you won't need to run straps around your stem or steerer tube. Since the Speedpack 483 doesn't attach to a stem, the 483 is also a great choice if you run a super low stem and just don't have the real estate to run straps around your steerer.

Like our other Speedpacks, the 483's advanced computer-designed shape, derived from a true NACA airfoil, maximizes the pack's aero advantage. And we integrated many of the same unique Speedpack features that reduce drag, improve on-bike stability, ease usability, and maintain high durability--please see our full feature list below.

The Bottom Line:  The streamlined Speedpack 483 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.
