Item # EDB0002


Many single speed cogs will take a toll on freehub bodies over time. Their narrow nature paired with a whole lotta torque makes for trouble. Our friends in North Carolina developed a brilliant solution -- the Endless Bike Kick-Ass Cog. A full quarter inch wide (6.35mm) at the splines, the Kick-Ass Cog simply will not damage your free hub body the way a narrower cog can. It's crafted from high strength 7075-T6 alloy (Stronger and harder than most common steels), right here in the U-S-of-A.

Endless Bike Kick-Ass Cogs are precision machined insuring perfect axial and radial alignment that compliments the superior chain lines that cassette style hubs allow. The specially engineered tooth profile on Kick-Ass Cogs improves both cog and chain life while minimizing drive train friction. Because of this, you can expect a smooth, quiet drivetrain -- no more grittiness.

I've used them with no issues on both 9 & 10 speed chains if that helps at all.
