BikeMaster 525x150 Bmxr X-Ring Chain for Powersports, Black/Gold

• The inclusion of a Q4 seal ring, along with reinforced pins and rollers, provides superior wear and impact resistance, making it ideal for demanding riding conditions
• The Q4 seal ring reduces friction significantly, which minimizes power loss and improves efficiency, with almost half the friction of typical O-ring chains
