Holds the spare tube, tire tools, patch kit
This is the perfect size to hold the tube, tire tools, and patch kit that I needed LAST week when I stranded myself 5 miles from home. It fits under the seat securely.
Perfect size for my purpose
My iPhone14 needed a better place than my jersey pocket to accompany me on rides. My old seatpost bag was not large enough, but I didn’t want a suitcase. This bag is perfect: spare tube, ID, house/car keys, and iPhone fit with a little room to spare. Fits neatly on my road bike, and is fairly light. Fabric is water-resistant, not waterproof, but that’s ok for my needs.
It works but could be better.
The three bag straps could be better. The seat post strap should be a one-piece design with a loop to allow the strap to double back upon itself and become tighter against the seat post. The under the saddle strap should have smaller buckles so as to easier fit under some seat designs. The rear strap for the "blinky" light is mounted too low on the back flap which offers little support to an attached light thus allowing the light to tilt downward and flash at the rear wheel rather than straight backward toward traffic.
