EAI Gold Medal Pro track cog

Without a doubt, the finest 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 this with an Izumi Super Toughness chain and a top quality chainring like a Sugino Zen to fully optimize your entire drivetrain's performance (and achieve unlimited baller status on the track or the street).   Each size features a different color hand-painted stripe and matching pouch w/ magnetic clasp and embroidered EAI logo.   FYI: All track cogs have 1.37"x24tpi threading. ALL OF THEM. Any threaded cog can be used on any threaded track hub. Specifications • standard 1.37"x24tpi threading • sizes: 12t-18t • chain compatibility: 1/8" • polished gold/silver finish Produc
