If your chain has tight spots, it may be time to replace it.My K8 showed-up Today unexpectedly. STI gave me a free cycle cover. Not going to rush into things and need to get the sea legs back!. Everyone said that is a big bike. Nobody said it was ugly, just big. I am loving the thought of getting to know it. Fork brace and 16: 43 chain and sprocket's? Is 6th. that bad?. The chain has some tight spots.
