Product Details

The Q4 seal ring in this BikeMaster 520 BMXR chain is designed to offer less friction than standard O-ring chains, which helps minimize power loss. This chain is built for durability, with components refined through computer analysis to provide higher tensile strength and specially controlled heat treatment for tougher material. It’s a solid option for replacing your OEM chain, offering 1.5 to 2 times longer wear resistance compared to regular O-ring chains.
