FIT Bike Co. BMX Headset

The FIT Headset is an integrated campagnolo-style BMX headset designed around the lowest achievable stack height, keeping bars as close to the head tube as possible without compromising bearing quality or adjustability. Built with 45°/45° angular contact sealed bearings and compatible with standard 1-1/8" campagnolo Hiddenset integrated head tubes.

Key Features

• Minimal stack height — Designed to sit as low as possible within the head tube, reducing the gap between the stem and top of the head tube for a cleaner front end and lower effective bar height without changing stem or bar specs
• 45°/45° angular contact sealed bearings — Angular contact bearing geometry handles both radial and axial loads generated by steering and riding inputs; sealed construction keeps contaminants out and reduces maintenance frequency; 41.8mm O.D. is the standard dimension for integrated campagnolo-style headsets
• Integrated campagnolo Hiddenset compatible — Designed for frames with a campagnolo-style integrated head tube where the bearing races sit inside the head tube rather than in pressed-in cups; confirm your frame's head tube spec before ordering
• Spacers included — Supplied with spacers for fine-tuning stack height and steerer tube length management during installation

Compatibility and Ideal Use Cases

Compatible with frames using a 1-1/8" campagnolo-style integrated head tube — not suitable for frames requiring pressed-in cup headsets or non-campagnolo integrated standards. Confirm your frame's head tube specification before ordering. Best suited to riders who want to minimise stack height on their front end setup or who are replacing a worn headset on a compatible integrated head tube frame.
