Product Description

The 6MIL CB-01 Chain Breaker is a compact, precise, and durable tool for 1/2" x 1/8" BMX chains.

It includes a spare replacement pin and a stabilizing bolt that keeps the chain perfectly straight while pressing the pin — absorbing pressure and preventing misalignment. This ensures the drive pin moves smoothly through the link, extending both chain and tool life.

Unlike most chain breakers, the 6MIL CB-01 features a redesigned seating lip and alignment system. 6MIL perfected the lip’s geometry and position, so the chain remains perfectly aligned when the pin is pressed — eliminating bent pins or broken lips. This refined design solves one of the most common issues with other tools, offering smoother operation and longer durability.
