I've got a superstar headset with cartridge bearings installed and there's a bit of a creak when I rotate the bars to the left
I know the SS bearings are rubbish cos when I took the forks out before, the lower cartridge separated from the inner race. I just greased it up and put it back together but it's probably died now.
Anyway - does anyone know what size bearings a superstar uno headset takes? Think I remember 36x45x45 but really unsure
