Looking for a NOS or VVGC Shimano 600 headset in english thread. Required to replace a unit that has seen better days and appears to have a spacer washer missing (and also goes tight around centre).
Thanks I will keep it in mind but would prefer new - are the bearings in any way serviceable? I think the problem with the current one is that the bearings have been gritty and I don't want to fit something thats going to start doing the same thing.
