For those who don't have to constantly adjust their seat-post, this the the perfect clamp for you. CNC'd from a block of 6061 aluminum and then anodized in a wide array of colors, the Supercross Seat-Post clamp is light and gets the job done for a low cost. We just found a left over box of these in our warehouse prepping for 2013 product, and we are blowing these out for a low price! There are only a few left in each color and size. Make sure to get yours today, because once they are gone, they are gone for good.
