Very literally 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 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).
FYI: All track cogs have 1.37"x24tpi threading. ALL OF THEM. Any threaded cog can be used on any threaded track hub.
• standard 1.37"x24tpi threading
• 1/8" only
• each size has a different color hand-painted stripe and matching pouch w/ magnetic clasp and embroidered EAI logo
• polished gold/silver finish
