Don't think they're related, but there is a very fine paint & repair shop in San Lorenzo, CA named D+D Cycles. Rick, the owner, paints Ritchey's hand made bikes (not many these days), and high-end Rivs (e.g. Saluki). He's also a great person to work with. Rick has repainted a couple of frames for me, has one in his shop right now (top tube dented in shipment) and will paint some of my current projects.
Sharing his shop is a very fine frame builder (who also does frame repairs) named John Tallerico. John used to share space with The Bicycle Outfitter in Los Altos but moved recently after TBO was acquired by Palo Alto Bicycles.
I recommend them both to list members. D+D does not have a website, and Rick doesn't do email. His phone number is 510-278-2976.
