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

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.

Price , value, quality! Rockbros finds quality and sells cheap. There are tons of products out there but I know I can trust them

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!

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 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

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 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."

Bought medium size to pair with a seat bag. I use the seat bag to carry most of my emergency repair equipment so was looking for another bag to fit other items. Was able to fit cash and credit card/ID, mobile charger and charging cord and other smaller items. Don't need it for my phone, but seems like I would be able to slide mine in bag if necessary (newer iPhone). Sat out in a small rainstorm during a ride and seemed to keep everything dry. Fits cleanly on tube of my bike and doesn't shift much if at all while riding. The straps are a little long, but I just tucked them through the loops or you could probably cut them down. Wouldn't use this as my primary bag, but a perfect complementary bag.

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.
