Cervelo S2 BB Noise...loud!

Hi all…2014 S2 started ruminating some odd noises from the bottom bracket area. Pedaling forwards/backwards, more pressure upwards/downwards, none of these made a difference in the cracking noise. When it first started on a 60 mile ride this past Sunday, it was a low pitch crack with every revolution, then become louder and louder. With the carbon frame, it would do the ‘carbon-echo’ and was becoming slightly concerning. After about mile 30, the noise completely stopped. Im going to head to the LBS but needed to hear some feedback from the group.

Thanks everyone! -Matt

I wouldn’t rule out the pedals.
