box-three-prime-9-chains
box-three-prime-9-chains, The Box Three chain is polished and then chemically treated to achieve corrosion resistance. All Prime 9 chains have chamfered shifting edges, solid plates and solid pins to safeguard durability. Our unique inner link spacing is engineered to grab those modern wide/narrow chainrings. We chose to modernize the 9-speed platform due to the chain's spirited reputation.They also work well with BMX 3/32" Chainrings and Cogs.SUPPORT MATERIAL Prime 9 Technology(TM)View Prime 9 Drivetrain Compatibility ManualHow is the Ebike variant different?View Prime 9 Comparison ChartView Prime 9 E-Bike Comparison ChartWhy Prime 9?
