Very large top tube bag

I'm looking for a large top-tube-bag. I already have frame bag and saddlebag for my other needs and need a bit more easily accessible space (for phone, sunblocker, glasses, powerpack, wallet etc.).
i found this Blackburn TT bag that is 9.25"x3.15"x4.7" and it is about $40. All other bags i found were smaller.

anyone an idea of an even larger bag or a cheaper version?

(and no, don't want panniers, racks, backpack etc.)

I doubt they make them much bigger. The problem with a big top tube bag is that they tend to get a little top heavy, since they sit on the top of the top tube, and want to lean from side to side. And even with a small top tube bag on my bike I occasionally hit it with my knees.

Depending on your bike, if I were going bigger and I didn't want a rack, I'd want a handlebar bag rather than sometihing big perched on the top tube. Milton's right on here--the physics of balancing a top heavy load on the top tube are problematic, especially as every turn has an assymetric effect on the bag..

Different handlebars can accommodate different bags, so this might actually involve some hands-on shopping. I'd probably recommend that for a top tube bag as well as you really need to know a bag works with the geometry of your bike, especially if you're going for an unusual size.

My go-to for well-made reasonably priced bags is Banjo Brothers, their top tube bag is a little smaller, but it is about half of the price of the one you're looking at, and their stuff is high quality.

Maybe a used bag, originally designed for beam bikes.
Measures about 15”X3”xthin

Here's mine. It's a Blackburn, but I don't see a model no. I got it as a gift, so I dont know the cost. It is 3 x 3 x 6 inches. It has a zipper top with a clear phone window. It can carry, phone, two tubes, Co2s, a multi tool, and a couple of gels. I usually carry one tube and a cheesy cable lock for local short rides. It has 3 velcro straps that hold it pretty well. It looks kind of clunky on an aero bike, but it works pretty well. In the side shot, the zipper top is partially open.

Check out eoGear; they make excellent bags, including some large top tube bags. I have a few of their top tube bags on various bikes, and I really like them. My oldest is somewhere around 6 years old, and it has held up very well. Oh, and they're made in the USA if that's something you value.

Good point on the weight swinging around. the knees likely won't be a problem for me. i have a sort of top tube bag that has like saddles on each side and don't hit knees with that (that one is just too small - it is not high at all - and in use on my other bike)

I have a handlebar bag, but didn't like it. It was in the way of my lights and quite heavy for what it could carry and likely aerodynamically bad.
The bike in question has a Jones H-bar and I have a bar-bag (still testing if it works for me). so a regular handlebar bag won't work anyway.

Reason for a large bag is to have as few bags as possible. many smaller bags add lot of weight and are less flexible for relatively bulky items. I have a seatpost bag i could use, but for wallet, phone etc. i rather have it in front of me fo easy access. For example when i go to a Park restroom I take wallet and phone with me for that minute.

My triangle already has a custom frame bag. that holds all my tools, spare tubes and hydration bladder. But with battery pack, sun cream, mosquito spray, wallet etc. it gets tight. I don't want to wear stuff on my if possible. I wear normal T-shirts, so no Jersey pocket (and again, don't want stuff on me)

Interesting reading your thought process. Balancing these considerations is definitely more art than science, and a sincere thanks for taking the time to explain your reasoning. .

I had a Revelate "Gas Can" bag, which is reasonably large" combined with a saddle bag and on my new bike decided to ditch them both for a smaller frame bag (Banjo Bros. "Minnehaha" medium). I am much happier with this setup so far, honestly:



My frame is a 61 so it may hog up a bit more space on a smaller frame. The Revelate is a well-made bag but the floppiness of it annoyed me, even though it never interfered with my pedal stroke.

Not a exactly, top tube bag, but two of these work great for me and hold quite a bit. Got them on eBay.

Not sure if you guys misunderstand. I already have a frame bag and use the triangle as efficiently as possible. i was looking for something ON TOP of the top tube, like the bag i had found myself.
BTW, I really recommend the custom bag by Rogue Panda. Pricey yes, but saves me all the little bags and keeps tools, tubes, water bladder etc. low and in center.

Looking for something like this? I dont know if it is big enough for you (Sorry, just realized, dont have enough karma to post pictures yet)

Search for - "Aliexpress ROCKBROS Bicycle Bags Waterproof Cycling Top Front Tube Frame Bag" in Google. Hopefully it should be the first link.

I got this bag from Aliexpress. Good for the money that I paid. It cost me around 13$ delivered at home in around 30 days.

Yep, they can get unstable and unwieldy real quick.
