I broke my chain on a mountain bike ride and I didn’t have a spare master link with me to fix it. I know that there has to be another way to fix a broken chain but I was hoping to get some good advice from a mechanic on how to do it. From: Sam


Because this is a common problem for many riders, whether on the road or trail, I made a  couple videos to show how fix a broken chain out in the field. The first one shows the complete chain repair process from start to finish.

To make the job a little easier, I keep a homemade tool with me that helps to hold the chain together while I am working on it. Here is a video on how to make this tool yourself so that you can be ready when the time comes.
