ACS Crossfire

The ACS Crossfire is designed for standard BSA threaded shells, which are 1.37"x24T. It is compatible with both 68mm and 73mm shell widths, making it a versatile option for most mountain and road frames using this common standard.

This bottom bracket is specifically engineered for two-piece cranksets with a 24mm spindle diameter. If your crankset uses a different spindle size, such as 30mm or DUB, this component will not be compatible.

The precision sealed cartridge bearings are designed to keep out dirt, water, and grime, which significantly reduces the need for frequent servicing. They offer a 'set it and forget it' reliability that is ideal for riders who want to spend more time riding and less time in the workshop.

Using forged and CNC-machined aluminum provides an excellent balance of high structural strength and low weight. This manufacturing process ensures precise tolerances, which helps minimize friction and prevents the creaking often associated with lower-quality bottom brackets.

Yes, you will need a standard external bearing bottom bracket tool to install this set correctly. Ensure you use a torque wrench to tighten the cups to the manufacturer's recommended specifications to avoid damaging the threads or bearings.
