25.4 X 330 BMX Black

Over 40% stronger on ultimate strength test than the strongest production seatposts on the market

The tube and head of the Thomson seatpost are integral-machined from one single piece of high strength 7000 series aluminum

Natural ellipse bore inside tube for optimum strength to weight ratio

Long 1.614 inch (41mm) seat rail grip length, this helps prevent seat rail bending from impact loads

Thomson seatpost design incorporates a bending fuse to prevent catastrophic failure

Clamp, head, and upper tube strong enough to withstand 350 foot-lb of torque, under severe impact the Thomson seatpost would bend slightly and allows the rider to come to a safe stop or finish the ride

Every component of the Thomson seatpost is 100 percent American made
