So I just picked up a 2011 SL2 8r carbon roubaix. I've had the bike for two weeks now and have rode a few hours every day. At first the bike seemed good and stiff and I only weigh 155. This morning I went out for a ride and the bike felt a little spongy so back to the house to air up the tires 120psi. Back out, same thing. So when I got home I pushed my foot against the bb and the amount of flex seemed to be excessive, like really easy and to much.
Do carbon frames lose some of there stiffness? Or is this normal?
I have inspected the frame for cracks,chips and found nothing.
Thanks. WC.
