The Mission Conversion headset is a practical solution if you want to move from a non-integrated frame toward a more modern integrated setup. It’s not a workaround, but a properly designed system made to bridge older 1 1/8” standards with today’s cleaner headset designs.
At the core is a Campy-style sealed bearing with a 41.8 mm x 45° interface. This specific angle and fit aren’t random. Under load, it runs smooth and consistent, without developing play or requiring constant adjustments. The sealed design helps keep out dirt and moisture, giving you reliable performance over time.
The kit doesn’t stop at just bearings. It includes a dust cap, spacer, star nut, and top cap, so you can build your front end properly without missing pieces. The steel fork race is a solid addition, handling impact and wear better than cheaper alloy alternatives.
This is the kind of upgrade you install, dial in once, and then just ride without thinking about it.
