Anodized Kick Ass Cogs

At a full quarter inch wide (6.35mm) at the splines, Kick-Ass-Cogs simply will not damage your HG free hub body the way a narrower cog can. Made of high strength 7075-T6 alloy (Stronger and harder than most common steels), 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. With a Kick-Ass-Cog on your bike, you can expect a smooth, quiet drivetrain for miles to come. We do not recommend ACS Crossfire or SRAM PC1 chains as they accelerate the wear on the cog. SRAM PC7X and 8, 9, 11 and 12 speed geared chains have shown no issue.

These cogs have NOT been tested to be used on e-bikes. Cogs used on e-bikes are not covered under warranty. For singlespeed use only.

Like all EndlessBikeCo. Products, Color Anodized Kick-Ass-Cogs are made right here in Western North Carolina; not in some faceless factory on the other side of the planet.
