I am a happy user of this kit on both road bikes but I anticipate that it is time for a change of cassette and chain on at least one bike. I will use the new Centuar which has 12-30T. What is the best chain option
- two new chains to be swapped every 1000k or so or one new chain only?
- Campag chain or that of a specialist such as KMC?
- is it true that Campag break links are usable once only?
