KNWU Cogs Shimano Dura-Ace Suntour NJS 14T 15T 16T

Vintage NJS Track Cogs – Shimano Dura-Ace & Suntour
 
A rare set of vintage NJS track cogs with a genuine connection to Dutch track cycling history. These cogs were used by the KNWU Dutch National Track Team, prepared and maintained by team mechanic Felix, and ridden by top athletes, including Leontien van Moorsel.
The cogs feature flattened teeth, a modification carried out on a lathe. This was done to reduce weight and is believed to minimize rolling resistance, a common high-level track optimization in the pre-marginal-gains era.
Set includes (detailed per cog):
1× Shimano Dura-Ace NJS – 16T, flattened (used by Leontien van Moorsel)
1× Suntour NJS – 15T, flattened
1× Shimano Dura-Ace NJS – 14T, flattened
2× Suntour NJS – 15T, flattened

Standard: NJS
 
This is more than track hardware, it’s a piece of authentic Dutch cycling heritage, perfect for collectors, display builds, or riders who value true race-used equipment with a story.
