The newer drive chains, especially O-ring drive chains, are constructed better better than the older drive chains. Therefore, you will discover a chain breaker really does facilitate the process of shortening a drive chain.
It was much easier to drive the pin out of older chains, especially conventional chains. However, I'm sure you will be glad you purchased a chain breaker when it comes time to drive the pin out of a newer, quality, O-ring drive chain.
