Izumi chains are made in Japan and are the mark of absolute toughness and quality. The ES410C is a 5/6spd chain, but is more commonly used on single speeds, fixed gears, and internal hub geared bikes that take a 3/32" chain. Also fantastic for vintage MTB and road bike restorations where you want a period-correct feeling chain for your 5 or 6 speed freewheel!
