ROCKBROS Top Tube Bike 840D Nylon Waterproof Bag Bicycle Front Frame Bag | Phone Accessories Pouch with Fiberboard Supports for MTB Road City Bike Compatible with Phone Under 6.8” (New 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.

I ride 150 miles a week from commuting to workouts. Holds a lot for such a compact bag. It's well made, legitimately waterproof, durable and easy to clean.

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.

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.

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.

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.

I got the medium Very great value for what it is Seams to be good quality Fits all my essentials and then some Here’s a list of what I keep in it on every ride Spare disposable contact lenses and eye drops, asthma inhaler, chapstick, 2 tire levers, ID & Debit card, 2 snack bars, CO2 canister & small inflater, small multi tool I keep my spare tube strapped to my frame so this has eliminated my saddlebag I much prefer the easy access of this bag Hold its shape well Looks good On other rides I’ve kept a charger in it for my phone and ran the wire out the top with the zipper barely undone I even use the Velcro straps under the top tube to hold some cheap safety glasses for rides where I know I’ll be riding at night I can then put my sunglasses there when I switch This bag is much cheaper than any other bag I’ve seen of similar quality About to use it soon for touring & bikepacking

I am upgrading my review again to 5 stars. I originally had an issue with the zipper sticking but it was easily fixed by rubbing (of all things) Carmex along the zipper path. I have had the bag for 2 years and nary an issue since. I highly recommend this bag. It has stood up to heavy gravel riding, the weather and the test of time. Original 2 star review: "I was looking for a top tube bag a little bigger than the last RockBros bag I bought. This one works great. Just the right size, fits on my gravel bike frame fine, but . . . the zipper is really hard to open and close. My other bag doesn't have this problem."

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.

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.

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.

Slim design and rigid walls, bag stays up straight and I no longer have to worry about chafe while riding as my knees use to rub against my old bag on the top tube.
