So I got the fork put on and it must weigh at least a pound or more less than the old fork! The bad news is that the headset was not compatible, as the inside of the headtube was machined to a depth of only 7.2mm vs the standard 8mm.

I returned the ZS-3 headset, but am now interested in swapping out the cone to a shorter cone (like with the VP-A48A). The problem is that I can't find anyone that sells replacement VP parts. I also need the plastic seal that goes underneath the cone and no one seems to stock those either.

Any ideas?
