Agreed! Worse, tandem carbon forks "fit any 700C tandem" - sold by a well-known and well-respected tandem maker (Co-Motion). If I put that into my Jack Taylor, which now has a huge fork rake, the handling would be dramatically different. I doubt it would be an improvement... (especially since that handling would be hard to improve).
A guy came into Il Vecchio's recently, riding his Colnago (I don't work there, but happened to be in), and said "I need a carbon fork, for a 1" threadless headset. Do you have one." I left the shop before I could say anything to discourage the guy, leaving it to George to deal with him. I am so glad I don't sell bikes!
I hope you are OK with my posting your response and my response to your response to the list.
