Review on 🚴 KOM Cycling Saddle Tool Roll Bag - Ideal for Road, Mountain Biking, and Gravel Cycling - Innovative Alternative to Traditional Saddle Bags - Includes 3 Pockets and ATOP Dial for Easy Tightening! by Alfonso Alexander

I had a hard time finding a tool bag for my gravel bike with a dropper. This one is perfect! Fits a gravel bike steerer tube, two tire levers, a multi-tool and two CO2 cartridges as well as a cartridge inflation tool. Attaches firmly to the seat rails and STAYS IN PLACE! This is very important on a bicycle with a seat post, as these are not attached to the seat tube and do not have to be. The pockets securely hold your essentials and the pockets close with a flap to keep dirt and the weather out (mostly). Also the cheapest alternative!
