What is in your Trek downtube?

Just picked up a used Domane and…what do you guys have stuffed in your downtube? I didn’t get the flat kit bag that gets stuffed in there…I wrapped a multitool, a tube, and a couple of C02 tanks in fabric and put them all in there, it seemed to fit pretty well and with smarter packing I think I might be able to squeeze even more stuff in there (tire boot, fiber spoke, maybe even a mini-leatherman too.)

What do you guys have in there? Is there a multitool that fits in the door of the hatch?

I assume the Domane opening and compartment is smaller than the one on my FUEL EX but in the fuel I carry a multi tool, derailleur hanger, zip ties, some first aid stuff, and a quick link

Yes. It is stupid expensive for what it is but fits perfectly without rattling, is pretty small & light and does what I need it to do. I have the sleeve that came with the bike and just have what they intended in it. Tube, CO2 cartridge, CO2 inflator head & levers.

On long days with big changes in temp (Wisconsin) I’ll put my lightweight vest in with the tube kit. It’s a tight squeeze, but it’s night to keep as much stuff off my back as possible. I love that thing for bike packing. That little extra space goes a long way!!

I have a Specialized Diverge. I can fit all maintenance tools and parts in the downtube.

  • tube
  • boot
  • plugs
  • patches
  • pump
  • CO2 + head
  • tire lever
  • multi tool
  • lube
  • chain brush
  • chain tool
  • quick link

Sounds like a lot. But everything is small except for pump and tube.

I’m getting a new trek Fuel frame with integrated storage. I hope it can fit similar.

I just wish it had a chain tool with it. Admittedly I’ve only broken a single chain in my life (back in '95) but it’s a show stopper if it happens. I might rummage thru my box of old crappy stuff and see if I have a multitool with a chain tool on it…if I have one and it’s small I could remove it from the old crappy multi tool and stick it in the kit. Thanks for the link!

I like this list! But…what’s a chain brush and what is it for?

Joe

I take the head off this and use it to brush down the chain when needed before applying more lube.

Helpful on long dusty gravel rides.

That would make it go from petite to pretty massive and heavy which I’m sure Trek wanted to avoid. I carry a KMC Mini Chain Tool along with a couple of extra CO2 cartridges plus some odds and ends in a Lezyne Caddy Sack - Small which goes in one of my jersey pockets. The chain tool is small and might fit in the sleeve but I carry the Caddy Sack anyway since there is no way I would venture out with only one cartridge I just stuck it in there. There is no way I would venture out with only one cartridge.

And stuff.

I’ve just got a Checkpoint with a Di2 battery opening. I squished a tube and CO2 pump in there.
