I'm 57 kg so multiply stiffness from me to you by 0.57. Further you're on a bigger frame so likely for the same frame model mine is already likely stiffer.

So I concur with the "sweet spot" comments.

i would not worry much about stiffness but much more on your riding position. you need to have a bike with balanced stiffness. its like choosing the s-works sl4 over the cannondale evo just because it stiffer.

:noidea:

Larger carbon frame sizes almost always employ more material to result in stronger and stiffer frames despite the larger triangle because the intended audience will necessarily be heavier.

Right there with you DJ-shorter riders on smaller frame would want more vertical flex and stress less about torsional or drive line stiffness. My system6 is a massive 60cm frame. The triple butted frame of course was pretty large as well. I thought the system 6 would rider harsher than it did, but I was really surprised how much more forgiving it was than the smaller OD tube of the triple butted frame. The rear of the system 6 is Al as well. If given the opportunity I would love to rebirth the system six frame manufacturing its a great frame-naked clear coat with polished or ano rear ends mmmmmm.

It really just comes down to another consideration for the kind of rider you are.
Is the frame stiff/forgiving for the type or rider you are- and of course does the bike fit you properly!!

This post reminded me of why I'm not selling my system six even though I have an evo. Shame that the system six is the 'foul weather bike' but I just can't bear to part with it.
