Once you clamp the Crank Brothers Cobalt 1 Seatpost to your bike, you'll be way, way faster. That's assuming that you start intensive training, quit drinking, and get on some super-athlete diet at the same time you install the post. The Cobalt 1 is made from tough 6061 aluminum. It sneaks in under 300 grams and won't open the teary-eyed floodgates the next time you look at your bank statement.
