FSA Orbit Tapered Zero Stack Headset
The FSA Orbit Tapered Zero Stack headset has two options. One is for a frame with a tapered head tube using a fork with a tapered steer tube. The other is for a frame with a tapered head tube using a fork with a straight 1 1/8 steer tube.
i really appreciate parts that don't require much maintenance or worry, and this headset has been one of them. i have put on 1000+ mile and haven't had to think about it once. except to wipe the mud off it when i do something stupid on the road bike.
