Any 300 lbs plus people ride a Triathlon Bike?

I am not 300+ anymore so I can't speak specifically to your question, but...

I bought my Cervelo S5 (aero but not tri bike) when I weighed about 315, I did my research and found that Cervelo had no weight limit on the frame - so I would say that there are likely options that would be okay from a carbon frame standpoint. They do say that certain components may have weight limits so that would be something to think about.

As for the tribike position, I just got a Cervelo P2. I have not had an in depth fitting done yet as my fitter and I decided, due to my schedule, that we would do the fitting when I brought it back for a "10 hour checkup". At about 250 lbs with a "quick" (still over an hour) fitting and about 150 miles I notice...

a.) There are times that my belly feels like it is somewhat in the way. This makes it somewhat difficult to make a strong climbing effort and I think it leads to a bit of out of breath feeling, but it seems to be diminishing a bit so it might just be function of getting used to the different position.

b.) My arms, specifically my tricep area, tend to get sore rather quickly. This too seems to be getting better, but the first few rides I was only able to maintain aero for about 5 minutes at a time. I wonder if core strength vs. size may add to this, but that is strictly theorizing. As of last night I was able to ride about 75% of my ride in aero but still had to do some fidgeting around to keep my arms happy.

c.) I feel like (and GPS data confirms) I am taking a big hit on climbing. It just feels SO much harder. Not sure if being big has a larger effect on this than normal, but hills are currently a bit discouraging.

Not sure if these help at all and my opinions definitely may change once I have my fitting, but mostly I would recommend talking about your concerns with your LBS and taking a good length test ride before making a decision to buy something.

OH...And most importantly...CONGRATZ on dropping 140 lbs!!! That is awesome!!!

Those points are a HUGE help!! One of the things I was also concerned about was my stomach getting in the way.

Thank you for the tips and the congrats!

One of my good buddies has a P2, such a sweet ride! Enjoy it!

Thank you for sharing that Melon!! Lunchbox is the man!
