A "me too"; I watched a couple take delivery of their new tandem and buckle the front wheel within 10 seconds of climbing aboard. They turned to get off the sidewalk and into the street, and sproing, instant taco. This was a dished wheel for Phil disk, the first tandem we'd made for the Phil front at Rodriguez, I wanna say about '80-'82? We rebuilt the fork and wheel with 110mm spacing and had no more problems.

I built a tandem for Mr. Wood himself, unique in that he insisted it *not* have cantilever studs or drilled crown or brake bridge - no provision for any brakes other than the F&R Phil disks.

Harvey, can you tell if the one on ebay is the newer one with the thicker, less strippable interface between the fiber disk and the aluminum piece on the hub? Those were interesting brakes.
