I got a lightly used bike the other day and it's the first I've owned with internal storage.

I would put a tpu tube, levers, multi tool, plug kit, spare link, and my small hand pump, since I've kinda gotten away from CO2 on the MTB.

The bike came with a bontrager roll type bag. The trouble is that it's open ended and I'd really like a closed bag, since things can and will rattle out.

I would think that something like a Crown Royal bag would get the job done but it doesn't have thick enough material to prevent rattling. I'd be interested in something about that size and shape that's either made of thick polar fleece or quilted material like a thin nano puff jacket.

Does this exist? I'm probably capable of sewing it but with no sewing machine and limited time, I'd rather not.

My basic search online didn't really turn up anything I was interested in.

Can’t quite visualize “internal storage” on a bike. Can you post a pic of the bag you mention, and where exactly on the bike it is stored internally?

A lot of carbon and some aluminum frames have a door you can open and shove your junk inside. Bags are used so you don't lose your stuff inside.

This is the bag I have. https://www.trekbikes.com/us/en_US/e...e-bag/p/26634/

I don’t think you want anything that holds moisture.

Water does/will get into the frame.

My stump jumper came with a waterproof bag:

Specialized come with waterproof or at least highly water resistant bags. You don't want anything that holds onto moisture.

Also too poor to afford the Blantons?

This?? 12 in. Zipper Utility Pouch, Black Not Gucci quality but cheap and you could cut it down width wise and sew a new seam if needed.

Do not put a banana in internal storage and then forget about it for several months. Use a sticky note.

You post a lot of trash, however, this is solid advice.

1 gallon zip lock freezer bags work. Cheap but will tear. The Trek bag is bulky but organized. I like the look of that Specialized bag.

External storage FTW!

While one is an enduro style mountain bike, and the other is a touring bike, you're not exactly wrong.

Seems a tad silly since even a small camelback or small fanny pack can carry all the tools I'd ever need for a bike like this and I don't trust any cage to hold a bottle, based on the number I seen strewn across landing zones and the people hiking back uphill for their bottle, I don't think I'll be ditching the pack. Basic tire repair, basic chain repair, and limp it back to the trailhead. It's got a better chance of spending days on a chairlift than being 20 miles from a repair.

Maybe I'll put a rubber snake in there.

I like keeping my tools and stuff inside of the frame, nice and out of the way. Dropper posts don’t allow for seat bags, so the frame space is nice.

But - I can’t fit a tube for the MTB in there. So that remains an issue. I do run tubeless, but having a spare tube would be nice.

I bet you could fit a TPU tube in your sock.

Serious cyclists don’t wear fanny packs.

Snarky answer 1.
They do, they just call them hip packs.

Snarky answer 2. It's a mountain bike, of course they aren't serious.

FIFY

I received the Specialized bag today. Much nicer than the Trek one I had.

I managed to fit a TPU tube, multi tool, mini Leatherman, lever, plug kit, and spare link.

Technically I could fit the small Crankbrothers pump into the bag also, but when I did, I couldn't fit it into the frame.

I always ride with either a fanny pack or camelback, so there's plenty of room for a little pump. Actually, there's plenty of room for everything I mentioned plus a windbreaker and some food. I didn't need this, just playing with my new toy. If it rattles, I'll probably just use it for a tube.

Now this new/used bike also has the EDC cap on the fork. I doubt I'll be utilitizing it, I'll probably go back to the star nut. I don't like the idea of not being able to tighten the headset on the trail.

I have a Trek Domane and Checkpoint with the Bontrager burrito bag in each. I've never had anything rattle or come out of it. So, replacing it is a solution to a problem I don't have. But if you like the Specialized bag better, that's great.

I fit a TPU tube, CO2, and tire levers in my bag. I think a tire boot as well. Been 2 years or more since I've been into either of them so I might be forgetting something. I shove the bag up, a pump down, and a small first aid kit in the middle, under the hatch. I keep the things in there I would only need if I had an problem. I don't put anything I would normally use, like a wind jacket in there.

I run tubeless, but do carry my Dynaplug in my ride wallet which I carry in my jersey. Just so I can plug a hole faster when needed.

As for a pump, I sewed up a little bag out of some neoprene I had that came from a scrap of wire harness wrap. This bag, being thick and soft, keeps the pump from rattling. The bag is long enough that when I slide it down from the opening, the pump, in the bag, can rest down in the bottom bracket and yet the top of the bag is within easy reach of the opening to pull it out. It tucks in nicely along side the Di2 battery.

I get everything that I used to carry in a saddle bag into the down-tube storage. I don't think anything is functionally better, but the bike looks less cluttered without a saddle bag.

That looks like the value win by far. It's kinda a copy of bags sold by Klein tools, but a tiny fraction of the price.

Waterproof you want, but also breathability, otherwise you get rust, unless you put some dessicant bags in with the tools, like various stuff come packed with, also often in medication bottles.

How about posting one of these BITS compatible BIKES! Some of us don't get out as much as others and it's a little coy to be assuming everyone knows that bike frames now hold your stuff inside. As if ...

No.

If someone is familiar with it and had a good or bad experience with a certain type of bag, I wanted to hear their opinion. Or at least what they've done.

If someone is completely unaware that stuff like this exists, why would that person even care to offer an opinion? We don't all need to chime in on everything.

There are questions in the mechanic forum right now about DI2. Plenty of responses but none from me, because I don't have that on my bikes and I've never worked on it. It wouldn't make sense for me to offer anything.

I can read the thread, maybe learn a little, maybe look some stuff up, and put it in the back of my mind for a time where I might be shopping for something like that. It's one of the best ways to really learn about stuff, it offers a different insight than an ad from the company.

TLDR, bikes with internal storage exist. Look them up. Some are kinda cool.

I didn't mean you ...
