Well, I would never try to sell a repaired carbon frame, just because I wouldn't want to make anyone take that risk. Any bike shop or manufacturer will advise you against repairing carbon, but at the same time, I've seen Calfee repairs and have heard plenty of good reviews from others about them. Some say that the place where Calfee does the patch will be stronger than the original (but who can tell, really). So it is up to you what you want to do.
Did you have it thoroughly inspected by your mechanic for stress fractures elsewhere? Have you been over it with a quarter (the tap test) and a flashlight?
I don't know if I'll do any mass start races on my Roubaix frame when I get it fixed. It may not be worth it as a TT bike either, because I'd probably want a lighter, aero frame. So I think it could just be a spare. I'm leaning towards putting better climbing gears on it. Even though it's heavier and not as stiff, it'd still be good to practice on for some climbing.
That's weird about the sending in the frame. I know they do that for warranty, but I didn't think they cared about crash replacement. When I asked about mine, they recommended against repair, but I thought I could do that and get a replacement. The problem wound up being I could do neither w/in a month, and I needed a bike in 2 weeks tops, so I just said F* it and bought an S-works frame for a good deal from the local Concept Store.
