ACS Singlespeed Chain

The width you need depends on your drivetrain components. Most BMX and dedicated single-speed bikes use 1/8-inch chains, while many road-to-single-speed conversions or older multi-speed setups use 3/32-inch chains. Check the width of your existing chain or the specifications of your chainring and cog to ensure a proper fit.

This chain comes with 106 links, which is standard for most single-speed and BMX setups. However, you should always measure your current chain or calculate your required length based on your gear ratio and chainstay length before installing. You will likely need a chain tool to remove excess links for a perfect fit.

Yes, the super hardened steel construction adds a slight amount of weight compared to a standard, non-hardened chain. This trade-off is intentional, as it provides the durability required to resist stretching and snapping under the high torque loads common in BMX and aggressive single-speed riding.

No, this is a single-speed chain designed specifically for bikes with a fixed chainline. It lacks the lateral flexibility and ramped plates required for shifting gears, so it will not work on a multi-speed drivetrain.

You will need a standard bicycle chain tool to break the chain to the correct length and to install the connecting link. If you are comfortable using a chain tool, installation is straightforward.
