Totally love this bag, great size to hold my vest and a few gels, easy to stuff it in there or take it out while not having it in my rear pockets, perhaps falling out unnoticed. I have the large size bag as well, that stays on the gravel bike, and the mini on my road bike. Seems to add aero dimension as well!
This handlebar bag is perfect for my needs. I was looking for a small handlebar bag to fit a tube, phone, wallet, and bar during my rides, and this bag fits all of that. It secures itself in place solidly with the bungee cord attachment that goes around the steerer tube. I also am able to fit the batteries for my handlebar light in the bag, which is an added bonus!
The bag is perfectly sized. Not too large where it sags and clips you wheel. Not too small where you can't fit anything into it. Weight is also insignificant so you never feel dragged down.
Perfect size, easy access. The reason I gave this 4 instead of 5 stars is that the velcro handlebar loops are too big... it's **** to get tight enough.
