I am planning on changing my sprockets/chain next weekend. This is not a task I've done before, but I have been reading through a bunch of threads here as well as reviewing some YouTube videos. I am going to go with a 15/42 combo with a 530 chain (kit from SprocketCenter). My question has to do with which chain alignment tool would be best? When I started putting together my order on SprocketCenter, they had some recommendations, but I figured I'd ask the experts here.
