Hello All, I was in at the mechanics to get my new chain fitted when one of the guys mentioned that he had noticed that there was signs that my steering bearing was showing signs of wear. He demonstrated this by lifting the front wheel up and getting me to rotate the bars from lock to lock. Indeed he was right I did feel a 'notch' as I was rotating the wheel. I am happy to fit new bearings myself, but this will be the first time I have done so on a bike. My questions for you guys are, 1) have you any pointers/advice for me to make this job easier and 2) Seeing as this is just a slight notch and not noticeable at all when riding, how soon should I be getting this changed. Is it a serious and dangerous defect or will it be okay for a few weeks until I get time to work on it. Any and all advice is much appreciated.
