The EAI Superstar cog is one of the finest track cog on the planet! More thought, R&D, and hand work has gone into one of these cogs than most of the other parts on your bike. The track passionate folks at Euro Asia Imports had a goal of producing the smoothest, flattest and quietest track cog for world class, professional track racers, and that's exactly what they accomplished with the "Superstar." They took the time to go directly to the world class track racers at the ADT Velodrome in L.A. and asked them what they wanted in a track cog for use in world class events. The result is a cog that all others will be measured by from here on out. Each cog is made in the U.S. of A to ISO specs of ½” by 1/8”, of high grade stainless steel. From there each cog is then polished to a mirror finish. The teeth on the cog have been machined without a transition from the mid to top section of the teeth and come to a fine, smooth, thin point compared with the standard Euro-Asia cog. Each cog comes in a cool, orange wallet with magnetic clasp that sports the famous “EAI” logo. EAI recommends using this cog with higher end chainrings (Sugino Zen) and chains (IZUMI V) to feel it's true quality. The EAI Superstar cogs will be available in 13,14,15,16 and 17 teeth options.

17 Tooth Cogs are (once again) currently on backorder.  We will let you know as more become available.
