Carbon frame suitable for a 90kg 1.96m person?
I am currently riding a 63cm Trek 1400 and am thinking up upgrading to a new bike. I'm looking at the Argon 18 Krypton but am concerned that as I'm 1.96m (6'5") and about 90kg I'll be too heavy for the bike.
I imagine that an aluminium frame is stronger than a carbon frame so will I need to stay on an aluminium bike?
I ride about 100-200km per week and it is all road cycling, although riding in Sydney means that you go over more than your fair share of pot-holes and other cracks etc in the road.
What do you all think as I'd hate to buy something and crack the frame within months of getting the bike!
Thanks in advance for your comments.

90kaj is nothing. You will be fine. Hell I was trying to tear by TCR1 to peices at about 98kaj when I kicked things off. Granted it was 'talking back' but it never exploded. Did manage to explode my campag record cranks though.

The reason I ask is that I've just had to get a new back wheel as my Bontrager Select hub had more cracks in it than a building site! I just want to make sure the same doesn't happen with a nice carbon frame if I pick one up in the next month or so!!!

I'm 6'1" and 255 pounds and I ride 2 different carbons (see below, the Calfee and the Kestrel) about 75 miles a week each.
No problems with either bike.

I highly recommend the Neuvation M series wheels for big guys as well. They've been rock solid wheels for me.

Carbon frames have limited lifetime warranty anyway.....as long as its a design defect and it should have held up (most are designed for up to 100 kgs) its going to be replaced. I am talking about Trek, Specialized, Orbea etc etc...

Yeah the wheels are what you have to worry about. 90kg isnt super heavy - you should be fine on any decent carbon frame.

What would be your suggestion for wheels. I was thinking of picking up Shimano Dura-Ace wheels or maybe Mavic Ksyrium ES wheels. What do you think would be appropriate for me?

I'm 6'-3", 255. I prefer super-strong, weight weenies need not apply. My carbon road bike wheels are Dura Ace hubs, handbuilt to Deep-V wheels, 32-spoke rear, 28 front. I prefer stuff that's 'never ever worry' overbuilt, so it may be a bit overkill.

The carbon will crack on impact not from riding. Carbon can survive fatigue cycles in the lab quite well. In the real world one good crash could destroy the frame. The Bontrager hub is quite simply a POS...Bontrager wheels with low spoke count are pretty much OEM junk on most cookie cutter bikes on the market.
