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

Love this top tube bag, it is large enough for my iPhone and other things like snacks.

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 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 mediumVery great value for what it isSeams to be good qualityFits all my essentials and then someHere’s a list of what I keep in it on every rideSpare disposable contact lenses and eye drops, asthma inhaler, chapstick, 2 tire levers, ID & Debit card, 2 snack bars, CO2 canister & small inflater, small multi toolI keep my spare tube strapped to my frame so this has eliminated my saddlebagI much prefer the easy access of this bagHold its shape wellLooks goodOn other rides I’ve kept a charger in it for my phone and ran the wire out the top with the zipper barely undoneI 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 nightI can then put my sunglasses there when I switchThis bag is much cheaper than any other bag I’ve seen of similar qualityAbout 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.

Great product

I got the smaller size because I have an under-seat bag for bulkier items. The smaller bag looks good on the bike and is fine for a bottle of tire seal, car keys, pepper spray, etc. I really like it. My Canyon bike has tapped rivets for screws on the top bar, so I didn't need to use the included straps. I just drilled through the bottom of the bag and screwed it down. I've seen similar bags sell for two and three times what this one costs. Would buy another.
