ROCKBROS Top Tube Bike 840D Nylon Waterproof Bag Bicycle Front Frame Bag

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.

This bag has been so convienient for removing items from my pockets that loosely swing aroung in my shorts, or worse try to fall out, while Im riding. This allows me to keep them secured while still having easy access to them. Its also great at keeping them dry. The other day it was raining pretty heavy on my ride home. Including a few minutes where my bike was just sitting out in the rain before I came out to it to leave. Aside from a drop or two that made their way in when I was putting my stuff in there, the inside was nice and dry! Maybe a slight bit of dampness on the inside of the fabric, but nothing to complain about. Especially with how hard the rain was coming down. At one point the drops were hitting my arms so hard they started to sting a bit. Good product here. Zipper can be a tad finnicky at times but it seems to have a way it wants to be closed so once you learn that its fine. I just put a little chain lube on it to help it slide a bit smoother and its been fine ever since.

Held up great to 3500 mile of bikepacking. Waterproofing is on point. Can just slip in an average battery bank and some snacks. It can kinda slip around on the top tube unless you put something grippier down around the tube. The only issue is that it’s really quite difficult to close unless you stop and use two hands. just collapses on itself. But not a dealbreaker in my eyes.

This bag is perfect for what I want which is gels and bars but not wanting to put my phone in it. I love the bag although the zipper did break and RockBros sent me a replacement immediately! 👍👍

The bag is very narrow, sleek and attractive on the top tube, I chose this bag specifically because I didn't like the other bulky options for top tube bags, but it comes at a cost, you won't be able to hold too much in it... in the small size I bought at least. For my purposes it's fine, as I just wanted something to hold some money and my sunglasses, and maybe even fit a snack bar in it, but not much else will fit. Without the sunglasses I can put some keys, a tire patch kit and a couple of snack bars, or able to fit a bike tube in it which would take up most of its space. The bag sits sturdy on the top tube with its 3 velcro straps which was a simple install. I can't speak much for how water resistant it is as I didn't test that. I like that the bag have a kind of semi hard shell that holds its shape and not floppy and cheap looking. Overall I am pleased with this bag.

Bag is built as advertised. It has stiff sides and is roomy. Seems to be well made. Held everything I needed it to. The zipper is stiff but maybe w wear/tear or some wax it’ll loosen up. Not possible to open the zip w one hand as new especially when riding. Velcro straps seem ok and they include two; one long and one shorter. Now the not so good. On either of my road bikes the bag rubs on the stem when steering. Bag does shift a bit side to side when riding. My legs did hit the sides occasionally when pedaling. Biggest problem was getting off the seat to stop and stand over the cross bar without crushing the tail end of the bag. Total deal breaker. Wound up finishing the ride using it as a handle bar bag. I already have a small under seat break down bag and use 2, 22 oz fluid bottles so mounting it other than the cross bar is not possible. Sent it back same day.

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.

I was thrilled to finally get this because this type of bag is the only type that can actually fit on my MTB without it getting into the way. I can't have a saddle bag because I have a dropper, and when I drop my seat all the way, it gets really close to my rear tire, which will then rub when I'm on some narly techincals. Then my bike geometry is in such a way, I can't put one in the bike triangle..... since my shock gets in the way. Thus, this seemed like the perfect solution. To be honest it mostly works but I do have one gripe... PROS: - Large enough to put a ton of things in but not so large that it looks like a hiking back pack. - Good solid material. Took on rain and mud and it held up. - Solid velcro straps. They strap and don't come lose. CONS: - This is where I'm bummed. While the straps are great and keep it in place (mostly), the bottom strap, that straps to the top tube is not very well designed. The strap itself simply slides through a couple of slits on the bottom of the bag, which means, it slides around. Even with the strap tight and firm in place, with just enough force, you can shift the bag left / right. I experienced this on every ride thus far where I'd make sudden turns, or quick endo's , or take really fast burms.... think of the effect of a Centripetal force. So what happens basically is the bag is now greatly shifted to one side off the top tube, which causes to slighly slag downward, which then gets bumped by my knee. Sucky!

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.

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.
