ROCKBROS Bike Top Tube Bag - Waterproof Front Frame Bag Pouch Pack for Mountain & Road Bikes - Large

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.

Small, good manufacturing, comfortable, money well spent.

حلو و حجمه كويس

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.

Material súper resistente, de uso rudo para que puedas cargar tus herramientas sin dudar que estarán bien seguras y protegidas. El cierre es 100% hermético. Recomiendo totalmente este producto 👍🏼

I had to cut one of the straps so that it would sit neatly (like in the pictures) but that was no issue. The bag doesn’t look out of place on my bike’s carbon frame and stays in place well. Also narrow enough that it doesn’t hit your knees when you pedal.

Was using under seat bags, which would not hold enough stuff including my phone. Also under seat bags tore my cycling pants a couple of times. This bag is great, probably not as aerodynamic but I will take functionality.
