My first track bike that I raced was a Planet X Stealth Pro Carbon. It was pretty flexy. I'm a big guy and I make lots of torque. But still, aluminum is stiffer at the same weight.
Back then, I had a speed/cadence magnet on my rear wheel. During rolling jumps (think Flying 200M acceleration) the rear triangle would flex so much that the magnet would clack against the sensor.
It's OK for a $800-900 frame and fork. But, aluminum is better.
