The description didnt give an accurate representation of the size ,and it is slightly smaller than I thought it would be at 0.3Cubic Inches. However it will serve its purpose of holding my energy bars and making them easily accessible.
Its big enough for a patch kit ,multi tool, tire lever ,co2 inflator. Makes a great accessory for people who don't like using there pocks while riding IE me.
so there is no confusion like with the other cyclists who wrote a review. This bag is for frames with pre-drilled holes on the top tube.
Apparently the cycling enthusiast that left the bad review because they wouldnt drill holes in their frame doesnt know that this bag is designed specially for frames that have top tube mounts.
