There isn't a lot that can be done different on a Pivotal Alloy Seatpost, it is one of the most basic parts for your bike. So we tried to keep it simple. We make sure the posts are the same diameter from top to bottom so you can raise and lower your saddle at will. The heads for the Pivotal Saddles are cold forged for strength so it wont slip and slide and strip out on you. We use a light weight 6061 T6 Alloy for the post to keep it strong and light. We offer them in 2 sizes 27.2 for pro sized and larger race frames and 25.4mm for the Freestyle Frames. Tons of colors your basic Black anodized, White powdercoat, Mirror Polished, and a ton of other anodized colors, Red, Blue, Gold, Purple, Green, Orange and of course if you want the ultimate in a Pivotal post, we offer them in Carbon Fiber too.
