Stock Status: In Stock
Genuine MKS tug nut with an NJS stamp

Patented chain adjusters for track bikes. These are made of cast metal and have a simple and functional design. They make the chain tension adjustment dead easy, and prevent your mighty thrusts on the pedals from pulling the back wheel forward into your chain stays.

They incorporate pockets which accommodate track ends up to 5mm thick.
