I suppose I'm just looking for a bit of reassurance here. On Sunday I went out for a longish ride on my bent (Street Machine) and at the start I noticed that the headset was squeaking a bit every time I made steering adjustments. I've not had this in four years of riding the bike. It stopped after a while. I was going to book the bike in at the LBS for a servicing anyway. Is this a normal thing to happen and does it just mean that a drop of oil is required i.e. will it be a routine servicing item or is it likely to turn into a major repair?
