The Box Two Single Speed 1/8"x112 link chain's nickel plating adds both corrosion and wear-resistance to your ride. All single-speed chains feature solid plates and solid pins to ensure durability. They are compatible with 1/8" chainrings and cogs, making them suitable for a variety of single-speed applications such as BMX bikes, 26" dirt jumpers, commuter bikes, fixed-gear bikes, track bikes, cruisers, and retro-modern bikes, including 29-inch models.
