Yes, screw is backed out, cable is undone. Manually pulling cage out, it is short.
Can someone take a look at their Tarmac and check this dimension - chainstay to large chainring. I know, there's going to be variables and this one has the frame protector that adds 2-3MM. I'm measuring 12.5mm from the frame protector to the chainring center. Just trying to ballpark it right now. The derailleur travel is at least 7-8mm short. Thanks.
