Uberbike pads are better than SS IME. I like their Race Matrix pads and they have lasted well until I did a couple of rides recently in the peak district which killed them so they’re a bit fair weather to keep in all year, I replaced them with their sintered expecting them to be as noisy as SS sintered but they’ve been very quiet, bedded in well and feel pretty nice.
I’m a tart so use Renthal grips but I’d give Uberbike grips a go as a cheaper option.
http://www.akbearings.co.uk are very good and the cheapest place I can find for decent quality, I’ve bought from KATEC before but I’m not convinced they are genuine SKF/INA/EZO as they developed play in less than a year. Give them a bell and see if they do headset bearings. (Just spotted SS site is back up, I’ve had a few sets of their headset bearings and they’re fine but fill and cover them in marine grease as they will rust)
