Carbon is less resistant to point stress. Very strong in other ways.
Anyway, this "carbon thing" is way off-topic.

Not an engineer are you?

Noa

The whole concept of point load weakness is a load of rubbish.
Firstly there is no mechanical reason why any material would be more likely to fail from point loads than any other with the correct construction and design.
Secondly, high pressure, small area loads (which I believe are what you are referring to) will only be caused by impacts and they generally only happen when your bike hits rock during a crash. Rider weight has no effect on this sort of impact.
In this type of impact aluminium frames are often dented which can cause a weakness and lead to future failure, this doesn't happen with carbon.

Do you mind explaining what your problem is again?

From what I can tell from your original post you asked KHS what the weight limit was for your bike and they answered. You don't like the answer they gave but they have still answered your question. Then you went on to ask why your bike hasn't broken but they haven't replied. I'm afraid I agree with them not answering as it's a bit of a silly question. How are they supposed to know how your bike hasn't broken? Of course they could have replied simply saying they didn't know.

It's not unheard of for bikes to be pushed past their intended limits be that riding style or weight limits and for them to be absolutely fine. It's also not unheard of for bikes to never go anywhere near their intended limits but still break. Sometimes bikes break and sometimes they don't.

Specialized and KHS and two completely different companies making completely different bikes so of course there will be differences between the two brands. Some companies offer lifetime warranties on their frames but that doesn't mean I expect every company to offer them.

Did I get that right or have I misunderstood you?

I read the whole thread and conclude I dont care.

KHS have told you that all their bikes are rated to 240lbs you chose to believe there is another figure appropriate to your specific model. Assume you are right, it might be a bit more, 10% leeway might be acceptable. Whether its 240 or 264 you have two choices - sell the bike and get another or lose some weight.

Why can't all of there models have the same weight limit?

Cos carbon is weaker and xc bikes don't need to be as strong, silly

Because lighter people don't want to lug around a heavier bike than they need!

Just look at Stan's weight limits for their rims, very low, I bet the majority of riders (kitted up) exceed it, you don't hear of massive numbers of broken rims. I wouldn't apply that to the Podiums though!

But they can't put a weight limit on carbon because it gets weaker when its wet.

At last someone dares to mention the, err, elephant in the thread...

I read on the internet it just dissolves.

Now you're taking the p1ss. Carbon just gets a bit soggy when it's wet.

Read the post above yours. It definitely says dissolve.
And the internet never lies.

Is it like cardboard where it starts off damp and soggy and then dissolves?

Not problem is insoluble given enough water!
