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
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
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.
