EAI Gold Medal Pro track cog
Very literally the best cog money can buy.
Made by Euro Asia Imports for professional track use, the acclaimed Gold Medal has flawless threads, roundness and precise tooth profiles for the smoothest possible drivetrain ride quality.
The golden titanium-nitride plating over high quality stainless steel increases strength, durability and lubrication (if cared for properly, these cogs last virtually forever). Combine with an Izumi Super Toughness chain and a quality chainring like a Sugino Zen to fully optimize your entire drivetrain's performance.
