Park Tool`s latest top of the line chain breaker is built to last through professional use. Designed to drive rivets in and out of any bicycle chain from beefy single-speed half-link chains to the latest 13-speed systems. 

Ergonomic handle stores spare driving pins as well as a peening anvil used for peening Campagnolo 11 12 and 13-speed chains.

Unique triple-wide floating shelf ensures that every chain is securely fixtured and centered during use. Includes two spare driving pins and is fully rebuildable.
