In the process of turning my old bike into a fun, super fast road hybrid that no one wants to steal. So far I've replaced the front and rear shifter, rear wheel, brake pads, new casette, tyres. All spanking brand new stuff on an old bike, it's great fun. Test ride yesterday and there's definately a not so fun amount of clicking particularly when peddling up hill. It's almost deafening. Turning my attention to the headset, I've taken it apart and to my amazement there's no ball bearings in there. There's a compression washer of sort and a bunch of grease. Any idea what I'm meant to be doing here?
