Box Two Seatpost
Perfect for BMX Racing “Warm-ups or Cool-Downs,” this lightweight seat post is made from 2014 aluminum alloy, and a cold-forged aluminum alloy head gives the Box Two™ Seatpost a superb strength to weight ratio. The two-bolt head design ensures solid seat positioning and plenty of adjustment. Each post has 20 millimeters of setback and 26 degrees of seat angle adjustment.
Worked great, until it bent
Overall solid seatpost, as long as you aren't a bigger person. I rode it for a couple months before I notice it starting to bend just above the seatpost clamp. Very bummed.
