Will a centaur cassette perform and last as long as a chorus cassette? Also will the Performance chain by KMC work ok? Will the cassette wear faster with that chain over a campagnolo chain?
The Cenataur cassette should last just as long, the chain will work great. If you really want the most life from that cassette, buy 3-4 chains and alternate their use every 1500 miles, rather than using one chain until it's worn out before changing. You should easily get 3,000 miles from one of these chains and 4500 might be possible, if lubed and cleaned frequently. The cassette should last through all of those chains.
What casue chains skip is installing a new chain on worn cogs. If you alternate chains, that will never happen.
