Bicycle Seatpost Toolkit




About: I enjoy making things of all sorts, with an emphasis on bicycles, tiny/useful/just plain nifty devices, cartoonish arch-villany, and not destroying the planet we live on. If those last two thing sound contra...

This barely warrants pictures, but I'll upload them anyway.

I just put some tools (3 tire levers) and spare parts (valve caps, a schrader valve core, zip ties...) in my long 26.0 diameter bicycle seatpost. I then put a spare handlebar cap into the end to keep the stuff from falling into my frame.

It is a very simple idea, but I think it has potential, maybe hiding other useful things in the tubes of a bicycle.

Step 1: Laying Out the Stuff

One needs to figure out an arangement of the parts and tools that will fit in the seatpost. The levers only fit side by side with their hooks facing opposite directions.

Step 2: Put the Stuff in the Post

put the levers, small parts and zip ties into the hole.
'nuff said.

Step 3: Cap It Up

Put end cap into post, and reinstall seatpost.
No one is the wiser but you...

    Does the cap work loose after going over a lot of bumps? That's the only downside I can see to this elegantly simple, ingenious, trick. I've seen expanding "pipe stopper" plugs that use a screw to compress a rubber donut, which expands outwards and seals quite firmly against the walls of the pipe. With an eyebolt or wingnut on the screw, they're installable and removable by hand, and would definitely hold tighter than a press-in plug.

    Actually, I am glad you reminded me of that. A while ago, I took two conical rubber feet, which were probably made for the bottom of a stereo or something, and attempted to make endplugs for my handlebars on my other bike. I had overtightened the barends and squished the ends of the Aluminum tube a little, so I was looking for a device that would press against the inner wall of the handlebar and prevent any future damage by my own heavy-handedness with the Allen wrench (bike mechanic translation: slobbishness due to haste). That's why torq wrenches exist, I guess. It did not work too well, but I bet that same system would be just the ticket for my little toolkit here.

    A better solution (to add to it) is a one gallon ziplock bag. Put all that in lined up at the bottom, roll it up, and the extra bag will be easy to grab, and keep it from rattling. Thanks for the tip though, I will definitely be using this one.

    I used to do this during my mt. biking prime of the early 90's. A rubber stopper was my plug of choice, often with a useful allen wrench stuck on the inside. I found use of a $5 bill wrapped around the wrench when I was in need of food far from home.

    Good idea, but if you don't have a quick release seatclamp, you'll need a tool to take the seatpost out. Kinda defeats the purpose if you have to carry a wrench around.
