FSA Pig Headset

This headset is designed for 1 1/8-inch threadless steerer tubes, which is a standard size for many mountain bikes and BMX bikes. Before purchasing, verify that your frame uses an external cup headset design, as this model is not compatible with integrated or semi-integrated systems.

The oversized bottom cup is engineered specifically to handle the high-impact forces common in BMX and aggressive mountain biking. This extra material significantly reinforces the structure, preventing the cracking that can occur with lighter, thinner headset cups under heavy use.

Yes, like most external cup headsets, you will need a headset press to install the cups into your frame without damaging them. Because of the tall cup shoulders, ensuring you have a compatible press that can accommodate the cup depth is essential for a secure, flush fit.

The heat-treating process hardens the steel, making it exceptionally resistant to wear and deformation over time. This results in a headset that maintains its structural integrity even when subjected to the constant vibration and stress of trail riding or dirt jumping.

The FSA Pig utilizes sealed cartridge bearings, which are designed to keep dirt and moisture out for a long service life. While they are generally maintenance-free, they are also replaceable if they eventually wear out, allowing you to refresh the headset's smoothness without replacing the entire unit.
