Despite what many denying weight-weenies say, most full-carbon forks flex a lot, and often too much for bigger guys. Beefy forks with alu crowns and alu steerers flex much less.

Also, despite what many think, carbon steerers flex in the head-tube. It was pretty much proven in a test done by the German Tour Magazine

I've got rid of all but one of my flexy "bling" full-carbon forks for cheaper forks with alu steerers, coz I prefer the stiffness for the extra 150g or so
