Dura Ace NJS Track Cog: 1/8" x 18t (Near Mint)
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.
Mint very lightly used shape. Very slight ano wear from a chain, no visible tooth wear.
