The Speedpack 483 is our most advanced aero top tube-mounted fuel and gear pack. With its versatile mounting system, the 483 will fit nearly any bike on the road. Which means that the Speedpack 483 is compatible with new generation tri superbikes with integrated stems and/or aerobars. And the Speedpack 483’s 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 minimizing 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 (cables that enter the top tube vertically behind the stem). The Speedpack 483 can mount anywhere on your top tube and its advanced mounting system means that you won’t need to run straps around either your cables or your steerer tube. And, 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. Dark Speed Works Speedpacks are similar to other top tube bags, like those sold by xlab, but with more functional features, an advanced aero design, and made-in-USA heritage. 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.
