The KMC B1 Narrow is a dedicated BMX race powerhouse designed for 100% direct power transmission from cranks to the rear hub. Built with a heavy-duty bushed construction, it provides a 15% increase in pin durability, ensuring your drivetrain remains rigid under the 1,000-watt bursts typical of BMX sprinting. This 3/32" chain is engineered to handle the high-torque stresses that transfer through your frame and fork during aggressive gate starts. Whether you are pulling on the bars or clinching your grips through the rhythm section, the B1’s reinforced plates offer the 20% higher tensile strength required for competitive track and downhill environments.
