Clydesdales/Athenas (200+ lb / 91+ kg) - Another Weight Question

Hello everyone, I'm new to the forum and cycling too. A week ago I picked up an 07 Cannondale System Six that was a back-up bike for a road racer guy. The shop I purchased it at said the bike had a carbon front triangle, and an aluminum rear triangle. I currently weight in at 345lbs, but that is slowing going down due to running and now cycling. My question is will this frame be able to support my weight? I know the wheels are a major issue I am going to have to deal with. The current wheels are only 20/24 spoke wheels. I was planing on riding these wheels till I destroy them, and then pick up some wheels with a higher spoke count. So whats your guys opinion, will I destroy this frame with my weight or should it hold up?

Heres a picture of the bike. http://i21.photobucket.com/albums/b264/GrtSaint72/RoadBike.jpg

The bike looks nice, I have a C-dale too and enjoy it.

I think the frame should be able to handle your weight, but I would recommend getting some wheels that can handle your weight now, and save those ones for when you loose the weight and can enjoy them.

The frame will be fine.

Spend the money now and buy some stronger wheels.
There is nothing worse than to be out on a ride and have a wheel taco.
It's always a long walk home.

I would look into some cheap Tigra or 105 hubs with some Deep V rims 32 spoke double butted 3 x
Just get the hand built ones.

Then ride it like you stole it.

What wheels are those?

They are shimano R500 wheels 20 front 24 rear
