These chains have been our favourite for track bikes since our first Roma-Tokyo fixie in 2009. They're solid, straight and stiff.
1/2" pitch x 1/8" width
Silver and gold are plated for wear and rust resistance
Jet-Black have outer black oxide-coated outer plate, with indicated colour of inner plate and pin. Black&Black features gold pin.
These are a bit noisier than other chains on a fixed transmission, but it's nothing to worry about.
