I'm 6'3", 255lbs. Full carbon. No issues. Owned it since I was 300lbs.+
Just the wheels: broken spoke now & then, out of true here & there.

I have noticed when i am going down hill that i get the wobbles, does that have to do with the rims or my size. The bike is new, so i cant see why it would be the rims.

Probably technique. Have the LBS check the common stuff but it is probably technique. I ride a full carbon Kuota Kharma, down to 277 as of this morning, and have had no issues.

I used to race on a Trek 2100 in the early 90s. Carbon main tubes on Aluminum fork/stays. I weighed 215 and really hammered on that bike, and never had a problem.
If early 90s bonded carbon technology could hold up to a Clyde racer, then todays high-modulus carbon frames can certainly handle someone your size.
It's not the frame I worry about with lightweight bikes: It's the components. Shaving weight from all the tiny parts seems to make them wear out faster.

If you are worried about the weight contact Trek and find out what the weight limit is for that particular bike. I did the same with Kuota North America to find out what the limit was on the Kharma and I was told that the Kharma was way over built and there was no weight limit on the frame and fork.

You can tell if the headset is loose by holding both brakes, applying pressure dwon on the bike then rocking it back and forth. You'll be able to feel a knowck in the headset or play in the fork.
Happened to me about 200 miles after I bought my Lemond. Took it back, the shop reinstalled the hardware, no problem since!
Another time I rode my wifes bike downhill just for a test. I felt a light wobble. Spun up the wheel but it was true. Took it to a mechanic that suggested there was not enough tension on the rear wheel. He retensioned, no problems since.
-------------------------------------------------
If it continues, have the shop check out the fork. Maybe have another rider ride it for you to make sure it's not your handling skills. I';m sure many riders would do the favor for you, I know I would!
. Have heard of high speed wobbles cause by faulty forks. Shops replaced them as a fix. This is info Ive read in the maintenance forums. Biggest offender was Scattante bikes from Supergo/Performance. I believe I read of a Trek or two.

Well, considering the worlds heaviest person, one 5'7" Carol Yeger weighed 1,600 pounds at one point, then a frame designed tom hold 1602lbs would effectively have no limit, realistically though, few people over 600lbs would be able to ride anyway, so a frame capable of holding say 700lbs would effectively have no limit. Considering that bicycle frames make use of the strongest geometric shape (a triangle), that shouldn't be that hard.

You bought a Madone and didn't know if it would support you or not?
WTF?

If anything happes to it, Trek will replace it either way! You might even get a new Armstrong model now tha Greg is gone!
