The Primo Omniguard Sprocket was designed as a solid sprocket & guard combo to offer maximum strength & durability through ledge tricks. Made from 6061-T6 alloy that's fully CNC machined with a full wrap around nylon/fibreglass replaceable guard. The guard adds plenty of extra protection to your sprocket & chain whenever you're grinding & sliding ledges & will take a substantial amount of abuse before it needs to be replaced. With the supplied adapters the Omniguard Sprocket can be run on 19mm, 22mm & 24mm cranks. section Product Specs TYPE: Bolt-On
