Today I tried fitting my Trialtech Sprung tensioner to my new frame. It seemed fairly straight forward, and I got it on fairly easily. Now that the chain is on it, I'm a little bit confused. When i turn the cranks the tensioner jumps about and feels like it's skipping even though I've set it up so that there should be plenty of tension. Anyone have any ideas what the problem is? Could this be caused by the chainline being out?
Thanks for any help.
