Dura Ace NJS Track Cog: 1/8" x 16t (EXC+)
The DA track cog is the premier cog choice for Japanese pista bikes (and most others excluding Campagnolo built bicycles). Gorgeous flat black anodizing. Great for fixed gear urban cyclists as well! Inexpensive, attractive, long lasting, and lightweight! NJS stamped.
Excellent or better very lightly used shape. Some ano wear from a chain, no visible tooth wear.
