TubeFob: Handy Bicycle Inner Tube Luggage Tie

This is how I carry a strip of inner tube that can be used to tie down groceries etc. to the luggage rack of my bike. As fellow makers will appreciate, this stuff has many other uses.
Why not add inner tube to your Every Day Carry alongside paracord and duct tape!

Over the winter, on my rides home, I made a habit of buying more groceries than my rucksack would hold. Standing in the cold, digging through my bag, I could never find any cord or bungee. One time, I used my belt, but I have not yet resorted to my bootlaces! This stopped being fun . . .

Introducing TubeFob

Never again will you be without a strong, stretchy and grippy solution to secure your bicycle luggage!

Step 1: Tools and Materials

YOU WILL NEED:

Old bicycle inner tube
Paracord (or similar)
Keychain attachments: split rings; carabiner
Keychain gadgets (optional)
Bike bits: e.g. chain links (optional)
Scissors
Lighter (optional)

Step 2: Scavenge/Hunt for Inner Tubes

I have a big bag full of old inner tubes (they seem to breed).

Or you can go for a bike ride and pick them up off the road.
I have found many on my bike rides.
This is both picking up litter and recycling!

Or you could ask at a local bike shop.

Step 3: Slice and Wash the Tubes

1. Unscrew the valve cap and valve and add them to your spares box (waste not want not).

2. Cut off the valve section and discard.

3. Cut a few ranger bands (rings) and save.

4. Slit down the length of the tube along one of the seams.

5. Throw the tubes into the washing machine with your bike cleaning cloths (not your clothes).
This will remove all the powder and restore the rubber to shiny and grippy, like new.

Step 4: Cut the Tubes Into Strips

When dry, cut the tubes into strips about 1 - 1.5 inches wide.
Use the seams as a guide.
Long decorating scissors work great for this.
I usually get 2 normal width and 1 more a bit thinner (YMMV, depends on the tube).

Step 5: Get Knotty

The centre is just a cord loop with a big knot.
You can make it as long as you like.
Use the lighter to melt the cord ends, so they do not fray.

Make a simple overhand knot or get ambitious with a monkey's fist or lanyard knot.

for inspiration.
WARNING: Knot tying can be addictive.

Step 6: Assemble

I find that the best length for the inner tube strip is around 3 feet.
This makes a fairly compact fob but stretches to about 6 feet in use.

Wrap one strip of inner tube around the knotted cord loop, stretching slightly as you go.
Add a ranger band to secure.

Add a split ring or carabiner.

Step 7: Customise and Personalise!

Think of ideas for things to add to the TubeFob keychain or place in the centre.

TIP: You can make items keychain-compatible by taping a paper clip to them.

Alternatiely, you can store the inner tube around something you always carry, e.g. pump, tyre levers, puncture repair kit etc.

Step 8: How to Use

The strips usually hold with one overhand knot.
When tension is applied, the rubber grips itself.
For best results, as you tie, stretch the strips up to twice their length.

Thank you for your interest and encouragement.
