If you already had a hybrid and were asking whether you could meet your goals on it (i.e. finish a tri, etc.), the answer would be sure. But if you've already decided you're in the market for a new bike, I'd go road bike, hands down. I'm not sure what you'd hope to accomplish with a different hybrid.

I went from hybrid to road bike this spring (also for tri's) and I can't say enough about how much more fun the road bike is. I enjoy riding so much more. I haven't sold the hybrid yet, but I haven't ridden it either
