The SuperLight seat post by 12o'Clock Bikes is made from a 7075 tube with externally butted seat pin area to provide maximum strength which makes it suitable for mountain use. You may have noticed that other posts of similar style do not offer extra butting or material around the pin junction. From testing, that is what usually fails first. All bolts are titanium and the top yokes and cradles are also made from anodized 7075AL. The posts are hard anodized and all logos are laser etched for long term durability. The simple but effective seat clamp system offers maximum amount of adjustment and securely clamps onto the saddle rails with convenient torque markings. The anodizing and finish of the post is just stunning and is offered in a 410mm length which enables a good seatpost insertion for those of you who run a lot of post.
