Re:
That's correct, perhaps put a bigger end cap on the outercasing, probably a 6mm one will straighten it up and make smoother to operate.
The straddle cable needs to be able to move in thestraddle hanger so I can find its best position. Then tension it all up and work the cable sin the straddle hasn't sorted itself out yet, hence looks loose.
You'll then need to balance the put to the rim using the can't I tension adjusters to get it correct, even though its pulling slightly to the side.
But that is correct.
