'Why is my gear cable outer at a funny angle where it exits the cable guide!'
If there was a top ten bicycle build questions this question would be in it.

If you have the Campagnolo 'Divers Helmet' and many other similar styles of

braze on cable stops, the stepped ferrule is the solution for a neat cable exit.

A smoother gear cable run also helps to provide better gear shifting.

These ferrules suit all 5mm gear cables outers and have a 3.7mm insert which slots into the cable guide.
