Those ones are black red?
Hm, strange. I cant find the black/red combo on the crankbrothers website (exception beeing the 1/2", though that looks different).
Anyhow, I'll just check what happends
I didnt overtight it for sure and I have done some hours bicycling with it already. When I ordered the headset, I made sure I ordered one with the same angles as the raceface that was on there.
Most of my biking so far has been some hours with around 2 meter tall drop from walls and stones (slow speed drop in 2 gear). Have also jumped down stairs and such. So it should have gotten some strain already. I have yet to find play or any sign of damage, but I have only ridden for one day so far.
Btw. one thing that I had problems with, with the raceface, was play when I used rockshox fork. With marzocchi I never had problems, untill the bearing broke though
but then it was oooold..
