Here is your chance to upgrade your Seat Post Clamp with one of the lightest, carbon monocoque clamps out there. Weighing in at only 17 grams for the 31.8 and 18 grams for the 34.9, these weigh less than most of the high ticket clamps sold by Shimano or Campy. 

So upgrade your ride and save yourself a little more valuable weight.
