I did a 21 day tour of Nova Scotia with no more than that knowledge really. Bikes really aren't that complicated. If you have patience you can figure out how to fix most things.

When I was doing double centuries I went out for a training ride and my front derailleur snapped about 15 miles from home at the top of a big hill I had just climbed. Fortunately, I had cell coverage and Thom was around to come get me. I started working on removing the derailleur since it was hanging in the way and prevented me from being able to pedal. My reasoning was, I could stick the bike in the middle gear of the triple and be able to ride most anything back home.

I had never taken a derailleur off before. But it's just screws and such. What else I was going to do, hanging out by the side of the road? I almost had it all off when Thom got to me.

So my advice, just sit and look at your bike. Notice what's connected to what and how.

This is the tool kit I had with me.
