    Hi lads, my forks are starting to get quite stiff. Do I just need to take it apart & lubricate? gave the bike a proper degrease in case it was just grime but it's still very stiff.

    Carbon fibre forks, alu steerer tube, can I use automotive grease, copper grease, or just a drop of oil?

    Cheers

    Probably the headset and at the risk of being rude .... a trip to your LBS might be in order!

    The top bearing is sealed, with an alu ring sitting in it. Does this still need to be greased even though the bearings are sealed? Bearing itself seems perfect

    Bottom bearing was stiffer than top, so I swapped them, applied a little LM grease and reassembled. Nice fluid forks again ready for the gap tomorrow!

    If I'm buying new bearings what do I look for - 1 1/8" fork bearing? Are they standard?

    The bearings you need depends on the headset you are using - some use sealed bearings, some use needle bearings, some use round bearings in cages, some use loose bearings, etc. The make and model of the headset is often written on the outer face of one of the cups, but if not the best bet is to take the bike to a bike shop - if they don't recognise the headset then they can at least open it up to see them in the flesh.

    The lower bearings in a headset usually require attention sooner than the upper bearings since the lower ones get sprayed with water and crap by the front wheel. Some headsets use different upper and lower bearings so, stating the obvious here, but if you swap them make sure they are the same type and size.
