High-Capacity Aero Storage for Road, Gravel, & Tri Bikes with Direct Mount Top Tube Bosses

The high-capacity Speedpack 915D is similar to the Speedpack 915 except, instead of mounting with our advanced strap system, the 915D 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 high-capacity Speedpack 915, the Speedpack 915D is designed for longer races or for extended road, gravel, and/or triathlon riding and training. And the 915D's modified aero profile keeps aero drag to a minimum, which means more speed at a given power output.

Like our other Speedpacks, the 915D also has an advanced computer-designed aero shape, derived from a modified Kamm-tail NACA airfoil. 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 high-capacity Speedpack 915D will securely and conveniently carry the race and training gear you need on your road, gravel, or triathlon bike, while minimizing drag and helping you ride faster. The 915D is also large enough to easily fit most modern smartphones, including all iphone models.

NOTE: If you are a smaller person and/or have limited top tube clearance, be sure that your body can clear a 4" high pack mounted at your bike's top tube storage bosses.
