Hello everyone,

I'm new here, so I'll make my question brief. I'm in the market for a new carbon fiber bike, and I've noticed that there are many types of CF out there. Many are 3k, while others are 6k, 12k and even 18k. I know that this represents the how many strands of fiber there are per thread. My question is: does the more K equal stronger fiber? The BD Immortal bikes use 3K, while the BD Century bikes use Torya m30s which is I think 18k. I notice that Specalized upgrades there fiber every so often.

Now, I already know that you can make the bike lighter by using the higher K fiber, but is it just as stiff and will it last as long?

Thanks everyone.
