The Wipperman BMX IR8 chain is simply the best chain for use with track or singlespeed drivetrains requiring a 1/8 inch chain. It is fully nickel coated with reinforced plates. 10.6mm. 95 links with spring clip connector #11. Use it for race, grind or freestyle BMX, but it is here because of its rugged superiority for any singlespeed set up.
