My favortie bag
by Gravel Grinding Grandma

I can't believe how much stuff I can cram into this bag! I'm an ultra cyclist and often need to carry 1000's of calories with me to fuel my rides. Seriously, this thing is like Mary Poppins carpet bag, I can keep stuffing things in to it and it stays nice and slim and aero. Easy to open. Occasionally a little hard to zip closed because I've got it stuffed so full. Great product!

Not the advertised size.

I measured in advance the things I would need to carry in this bag. I chose it in part because the advertised measurements would work for me. Snugly, but work. Well, unfortunately, the advertised width is not correct. It's listed as being 5.1 cm, or about 2-inches. Two inches would have worked for me but the actual width is about 4.1 cm max, or 1 5/8 inches. Not a big difference but enough so that my wallet and a crunched-up spare tube wouldn't fit. And big enough difference for anyone else to take into consideration if they're thinking of buying. The build of the bag seems just fine so I'm just docking one star. It's the width that's the problem. The height and length measurements are fine.

Perfect little pocket

This was purchased for the top tube of my touring Rivendell Atlantis. While not the largest such bag, it is the perfect size for really essential things.

Excellent quality
by Kenji

I bought this for my wife's bike. She has used other top tube bags for many years but this is by far the most well made one. She really likes it.
