At a full 5mm thick, the Surly Fixed Cog Lockring doesn't mess around with cog security. It's CNC-machined from premium stainless steel for serious strength and durability. This sucker will hold tight through hard sprints and crazy skids. It's a small part, but an important one and Surly makes it right.
