I put a new chain on my bike last night. I didn't measure right the first time and took too many links off using my park tool. I went to add some of the links back on that I took off and I couldn't quite get them to go back together right. My technique was squeezing as hard as I could on the outside of the links with a pair of pliars to try and get the hollowpin back through both ends of the link. I thought I had it but about 5 mins into my test ride the chain came apart. Is there a trick to this?
