the lower bearings in my race face duce headset all fell out :huh: they were knackered
I now have a king and love it. I personally would go for a light weigh headset, they have to take loads more beating on a trials bike. Think about it, road and mountainbikes dont put much stress through a headset, but trialsriders do pivots, taps, hooks front hops, alsorts, much more than what light weight headsets can put up with.
