I'm in the process of ordering replacement gear cables for my road bike which has 105-5800 groupset. My existing cables have inline barrel adjusters and I was wondering:
- Are the inline barrel adjusters reusable? (I'm not opposed to replacing even if they are)
- If I have a barrel adjuster on the rear derailleur, do I really need an inline adjuster as well? (I need to verify setup for front derailleur)
- Is there an optimal position on the cable for them to be installed?
