I was about to buy a U.S.E. Alien seatpost with the Cyclops clamp for use with my Selle Italia SLR Kit Carbon saddle when I discovered that the standard 7mm clamp that comes with the seatpost will not work with my saddle, and that I would have to purchase a larger 10.4mm Cyclops clamp, which costs an additional $25.00. It seems to me that U.S.E. should offer its seatposts with different clamp sizes, or allow purchasers to exchange the standard clamp for one that will work with their saddle at no additional cost. I am now looking at other lightweight seatposts. I am open to any suggestions or advice. Thanks.
