ROCKBROS Bike Top Tube Bag Bicycle Front Frame Bag Waterproof Bike Pouch Pack Bike Phone Bag Cycling Accessories Pouch for Mountain Road Bike Large

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."

I needed a place for gels and an extra tube and co2 cartridge for my race. This worked great. I liked that it was semi-stiff so it didn't flop around against my legs. If you don't unzip it all the way, it can be zipped back up with one hand. Learned that trick. If I want to, I can put my iPhone 13 in it. It is just big enough. I got the next bigger one at the same time and returned it as this was the perfect size for what I needed.

Very nice bag for the price. I have taken it on many 300+ mile bike-packing trips and it is still holding up. I like the zipper right down the middle, makes it easy to access whatever you store in it. I would give it 5 stars but it tends to roll over from one side to another, making me hit it with my knees. Overall I would recommend.

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.

I liked both quality and appearance - yet, for me this one did not work as I wanted something semi-permanent that can be screwed to my bike frame. If you don’t, then this one is a great choice. Tried for fitting, and it’s holds a few items, to include my IPhone pro max.

I purchased the medium size bag, it fits a phone and wallet pretty easily. It was easy to attach, and the bag seems fairly rigid, but not inflexible. I never really got to test the water resistance, only had light rains that I was out in for not very long.The bag is that it seems to move around too much and it will make rubbing noises, which is a minor annoyance.My main problem is that the bag has also been very difficult to zip one handed, if I had a snack or something in the bag I needed access to while riding it would often be nearly impossible to zip without stopping and using two hands to stabilize and zip the bag... This leads me to my next issue, after 4-5 months of usage the zipper pull broke off, so now I need to find a new bag.

This is a great bicycle bag. I have three different bikes and have this bag for every single one of them. Some of my bags are over five years old. They are still like new and used a lot. I highly recommend this product. The zipper has never broken. The material has never faded and it is the perfect size for a couple of credit cards your cell phone, money and lipstick.

My mountain bike riding has on occasion needed items. Tire fix, occasional maintenance along with the upkeep I do at home after a ride. All of it is important, Bicycles now are sturdy and long lasting; this feature I enjoy to take advantage of. The other day my Markin shifter went out and with the tools I fixed it but at home had to add a special screw. In the past I broke a chain while riding and with my tools was able to do a temporary fix to ride home. this tool bag is convenient location so I can put a rear light for visibility to rear coming traffic. This item/bag does everything that my previous seat bag was able to do. I don't know yet if it is water proof but it looks as such.
