Review on ROCKBROS Triangle Bike Frame Bag, Triangle Bag for Bicycles with Dual Side Pockets, 1.5L Capacity by Montez Vazquez

I like this bag - it has good capacity and 2 zipped compartments - one wider than the other. This is a good place to get there while driving. The problem is that the angle between the seat tube and the top tube (directly under the seat) is nowhere near 90 degrees. One of my bikes (GT ZUM) has an exact 90 degree angle and the bag fits perfectly. My other bike is the SBC Black Label V2 - less than 90 degrees and the bag won't fit. Shaped to fit between the top and down tubes, but the straps are only on the top and back of the bag so that doesn't work. When it fits, it's very comfortable and roomy for me. Multi-tool, washcloth, snacks and battery. There is also a pocket on the bottom for a portable air pump.
