ROCKBROS Bike Top Tube Bag Bicycle Front Phone Bag Cycling Accessories Pouch for Mountain Road Bike

Excelente! mas de dos años de uso en cicloturismo, siempre al intemperie sol directo en el desierto por los últimos dos años. Sigue funcionando excelente, cierre hermético, velcros funcionales, rigidez prácticamente igual que de nueva.

The ad said not to worry about the sides bulging out. Well, they did, and the tools in it went to one side because of vibration when riding. With the tools on one side, it caused the bag to lean over to the left. The straps that hold it to the cross tube don't prevent the bag from leaning over. I overcame the problem by cutting corrugated cardboard and placing it on the bottom of the bag, and on the sides. It now works well, but I should not have had to do that. I would not recommend this bag unless you are prepared to modify it with cardboard.

I like the fact the quality is good and easy to installed. The only issue I had is the zip isn’t easy to zip up and down.

This is just the right size, I took it on a long tour. I used it for small snacks, power bank for the phone, sun screen. I had some heavy rain and it didn't get wet inside. The 3 velcro straps are over sized to fit any frame, I cut off the access straps.

great bag, stiff enough it hold it shape and can (if you are careful) be used one handed. One word of warning if your stem is low/slammed the front strap wont work and is not removable, I am super tall so I run 20-25mm of spacers and it's perfect. *I lined my bag with piece of plastic ruler and drilled it to fit my top tube mounts and bolted it on so I would not need the bottom straps, honestly should come pre drilled for as common as top tube bag mounts are now.
