I spoke with Harlan Meyer about 2 years ago about servicing ah old time trial front hub. At that time he was selling the rim business, but apparently still involved with hubs, selling Sunrace freewheels, etc. Don't have a number handy, but I found him with an internet yellow page search. He was still on School St. in Nashville, Tenn. Hope this helps.
Best Regards,
