Not my lardy, unfit stomach.
I've just about completed Mrs Atlaz's build and I have a slight bit of play in the fork/headset. Is there a "trick" to getting this tight because I've had a few tries and there must be a couple of mm that I'm not closing up but I'll be damned if I can figure out how to get rid of it.
You need to make sure it is from the headset. It could be play in the fork bushes, the headset, the disc rotor, the hub, the caliper, even rear shock bushes.
If it is from the headset, and you can't tighten it out, chances are the top cap is tightening against the top of the steerer, so you need a few more mm of spacers 🙂
If it's definately the headset but not being caused by that, there is a chance the headtube on the bike might be flared, and the cups are able to move in there. Fingers cross it's not that.
The cups are definitely tight, it's probably my inadequate spannering with the spacers.
Make sure you've got the correct amount of spacers in there.
spacers. I popped in a 2.5mm one. Spot on (i.e tight), rode- felt wobbly as. End of ride looked closely and it wasnt. the concave underside of the Chris King top cap is quite 'fat'- fat enough that it say ontop of the steerer and didnt allow enough purchase when moved slightly- 5mm cured it.
