Some of you might remember the carbon handlebar/F-150 torture test I did a while back. The carbon handlebar passed with flying colors. This time it's a full carbon saddle. This saddle is a Chinese brand, relatively easy to find and costs about $30.
First I tested it on my hard tail. I torqued the rails in a standard seat clamp that clamps top and bottom at about 12nm. It held up fine. Although very firm/slick and ridiculously lightweight, I didn't notice any durability issues or unusual noises.
Ok, onto the real test.
Ford F-150 (weight 5000 lbs.)
