The one sound I absolutely hate to hear when I am riding a bike is the POP! that comes when a spoke breaks. The POP! is followed almost immediately by DAMN! From me.
When you break a spoke, your wheel goes out of true. The rim rubs against the brake pads. And the integrity of the wheel is compromised which can lead to another POP! DAMN!
I tend to carry all kinds of fix-it stuff when I ride. I have tubes and patch kits and tire levers and a pump and a multitool and tire boots and master chain links and on and on. I draw that line at carrying spare spokes and cassette tool and a wrench.
No worries. Instead of becoming Joe Mechanic on the side of the road, you can pull out a fiber fix spoke instead. No tools needed. A fiber fix spoke is a kevlar cord that comes attached to a cam – a twisty thing for increasing tension on the cord.
Just remove the broken spoke. Then follow the simple instructions to install the Fiber Fix spoke without any tools. No lie. It only takes a few minutes. Check out this video. I am a mechanical idiot and I’ve done it one tours.
And off you go. I’ve heard of people using these for hundreds of miles way out West where bike shops are few and far between. The only downside is that you can get too aggressive and pull the spoke nipple right through the rim. Then you have screwed the pooch. Don’t screw the pooch.
The picture below makes it look much bigger than it is. The entire device fits in its own little plastic tube about the size of your thumb.
A Fiber Fix spoke will set you back about $15. They are re-usable so one should last you a long time.
A Few Spokes Shy of a Wheel 
Great tip. I have heard about them for years. This is the first time I have seen one used.
Ahh, yes… broken spokes! I’ve been haunted by them on too many trips.
I’m curious:
– what size tires do you run? spoke count? and if it’s not too personal: how much do you weigh? (I’m 6’3”, 230 lbs; use 700×35, 36h)
– do you carry a chain whip in case you break a spoke on the rear driver side?
– would love your reaction to this, if you have time:

Lots of luck on your upcoming tour.

With a fiber fix spoke you don’t need a chain whip. Just thread the kevlar cord through the hole in the hub and tighten. Pretty cool. I’m 6′ and anywhere between 200 and 215. Same wheel and tires. I used the fiber fix on the rear wheel of my long wheel base recumbent. The weight distribution is skewed 25/75 to the rear. Add panniers and it’s more like 15/85, Puts a lot more stress on that back wheel.
