I have a new full build Ti 456 from On-One (before Xmas) and I keep having to adjust the play out of the head set after every ride.
On-One Smoothie Mixer Tapered Headset 1 1/8 inch - 1.5 inch
I have checked that the steerer tube ends a few mm under the top cap, the only thing that seems off is the SFN is slightly skew. But I can't see how that'll effect play?
It's definitely the head set and not play in the brake pads etc... as I can see it moving.
What with that and the elixir problem, I'm not having fun.
