Why We Like The Kick Ass Cog

The Endless Bike Kick Ass Cog doesn’t make pedaling our single-speed rigs around any easier, but it sure does look good. These stylish anodized cogs are lightweight and simple to manage, made of anodized aluminum they style up our favorite single-speed or fixed gear rig. Kick Ass Cog’s are built to not damage freehubs, with their unique 1/4in design at the hub body any pedaling force is evenly spread out.

  • Anodized cogs are stylish and extremely functional
  • Made of 7075-T6 alloy material
  • Wide hub contact point means no freehub gouging
  • Specifically made for single-speed or SRAM PC7X chains
  • Machined locally in North Carolina

Best SS Cog I've Used

I've put it through the wringer

Doesn't take much to be spectacular in the SS category but the details matter if you want to set yourself above the rest and the Kick Ass Cog delivers. One of the most important parts is the freehub body interface as no one wants a cog destroying their freehub body and this one uses the widest base I've seen measuring at 6.3mm on my micrometer. Not only is the base wide, the precision machined splines fit tighter than most cogs so you'll have ZERO play on the freehub body and another bonus for not trashing it. Endless recommends anything BUT a single speed chain which causes premature wear so I've been using it with a 10speed chain for months with no signs of wear and no chain drops. If you can find your size, this is one of the best money can buy.

Does the Job

I've used it once or twice and have initial impressions

Finding a reliable, lightweight and cost effective rear cog can be tough. This one fits all three - thought a bit higher on price than desired. I suppose, however, that the 7075-T6 provides a serious sense of confidence that it'll stand up to tough climbs. In this case, I needed this gear to race Leadville and was completely happy with its performance. Never did it feel like it'd slip or compromise the hub with the torque I was putting on it. Also, I run it with a 10 Speed chain.


chain size?

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