I crossed the floor last year and bought a Focus roadbike. It's nicely specced with Shimano 105 stuff and other reasonable bits but clearly some cost saving was incorporated into the choice of headset. It developed play, so i snugged it up and now it intermittently gets sticky. I've stripped it down and it looks cheap (angular contact cups and caged bearings). Putting it all back together with new grease only helped for a short while. I'm therefore looking at replacing it. However, being more used to moutainbike bits, i'm not sure what size i need. It's oversized and integrated. Without knocking the cups out to measure the inner diameter of the head tube, can anyone tell me what size/spec i need?
It's for 1 1/8" threadless steerer and oversized head tube.
Cheers.
