Gobble gobble!

COBL GOBL-R

The idea is pretty simple.  They make bike as stiff as they can because it's supposed to help the power you put out get onto the road.  However that also makes the bike transmit the buzz and bumps on said road to your backside.  Specialized decided to build a magic seatpost that has a carbon spring in it that takes some of that harshness out.  It's worth a try - we'll see what it does.
