KMC professional quality chain breaker/tool.
Works on all chains including 1/8”, 3/32” single-speed chains and 5 to 11-speed derailleur chains. Made from investment cast steel.
- Fine thread and comfortable size for easy removal of even the toughest chain pins - the tool is design to not damage the chain pins.
- Intended for both single-speed and derailleur type chains
- Double sided pin and extra double sided pin included (you would have to break 4 pins before needing to buy a replacement - meanwhile I've never broken a single pin in my life.)
