Frame dropout cracked, what can I do? (Allied Alfa Disc / carbon)

1. Yes it's dangerous.
2. Contact Allied.

A crack, unfortunately, is a crack. That’s dangerous no matter what the material. You could contact Allied to see if you have any options in terms of warranty. However, if you didn’t secure the bike properly, I would guess that they’d offer a discounted frame at most. You could find a carbon repair shop, e.g. Calfee and Ruckus Composites are two well known ones in the US, and there may be others local to you. From one price list I remember seeing, dropout repair was more expensive than tube repair, so I’m not sure what the most economical option is. However, that can most certainly be repaired.
