My tri-bike is a Felt B16 with stock wheels and is an all carbon setup. In the off-season, I am hovering between 260-270, and will get down to 240 this race season. It feels perfect under my large self. I believe Felt rates their carbon frames up to 280lbs. I would hold off until you get into their specs. Though....a Felt frame with a 25mm tire and the correct wheels and it may just work. That being said, it all depends on your riding style and if you hunt for pot holes.
I have a Trek 2.1 that I use for my normal rides paired with the deep V's(32 via 105 hubs) and it has held up just fine as well. When I was 325, I stuck with a Raleigh Talus 29er until I got to 290. Us big guys have to swallow our pride and realize we are not the norm. But....when you pass the little folks, it does feel good!! Congrats on the huge weight loss!! Best bang for your buck is losing a pound vs. spending money on canon fiber.
