So I was installing a new rear gear cable for the first time, fairly new to bike mechanics. Got it to the rear derailleur. It went through the first part fine, the second part too. I was tightening a bolt on the second part that I assumed was supposed to tighten to tighten the cable, holding it so it would actually shift. Any ideas what I did wrong? Solution? PS this is all friction shifting... Here are some pics...
