Just removed headset cups so they can be transfered to another frame (identical frame, just different size). Looking at the bottom headset cup it looks like some of the black surface has worn away where it makes contact with the inside of the headtube. I'm guessing this is due to more water etc getting in the bottom headset cup area when riding, perhaps. Is it a problem if a little of that surface has gone? The headset is only about 5 months old.
