MKS Chain Tug 8mm thick

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 8mm thick.
