Why so few carbon fiber tri bikes?

why is it that most tri bikes are still aluminum or composite. I have a carbon road bike that is pure butter, but I need a tri specific bike and the options seem limited

What do you mean few choices? There are some great ones out there. Kuota, Cervelo, QR, Kestrel just to name a few. All of these companies make some great carbon bikes. I am sure I am missing a bunch which this group can cover better than I can… Good luck…
