Diamondback Top Tube Bag

This top tube bag is great! It has lots of storage and you can put your phone in the holder and use it on rides. This is a must for every rider!

Main straps slip onto a fabric rib, which feels sketchy but actually seems to work okay—not the easiest to use with gloves though. Forward one is also weirdly long. Guess I could trim it myself? Front strap has no quick release method (eg buckle) which is annoying. Keeps its shape well and I like the mesh pockets on either interior side. Magnets hold pretty well, unless the interior is fully loaded (holds a battery bank + cables, couple ratchet ropes, and my headlight when not in use). Pocket the phone slides into is barely big enough for mine, which is toward the larger end but by no means gigantic. Most annoying thing, though, was a total lack of openings for my phone's bottom ports (power, audio jack) so I had to choose between putting my phone in upside down (not ideal_ or cutting holes myself (also not ideal). Anyone with no need to charge their phone on the go or who uses only wireless audio when biking won't be impacted. This thing is so close to being 10/10, really only needs better attachment for the straps, an optional extra fastener to keep the lid shut, and holes for ports in the phone pocket. Keeping it since the price and quality are good enough that I'll just try to figure that stuff out myself.

Well I guess you get what you pay for! Does it serve it's purpose? Yes. Is it quality? Definitely not. The magnet that holds the cellphone is weak. Same goes for the straps. They're not sturdy and the bag never holds in place. I will save up to buy something better.

This is the most poorly designed product I have ever used. The straps are difficult to attach and tighten, and easily fall off when riding but it should be the opposite. It is a great product if you want the contents of the box to spill everywhere if you fall, or if you just hate the idea of anything being securely fastened to your bike. It's also great if you prefer a bag that rubs against your legs when you pedal.

Falls apart when tightened the velcro straps. Has no easy way to replace straps
