Even if you don’t care about Trek, Leopards or Fabian Cancellara, this video shows some rather impressive frame flex testing at about 3:20 in that makes it worth watching. For those that do care, this is part two of Trek’s Driven series of vids. The first one is after the break…


  1. That “frame flex” in the video is actually basic EN testing done on all carbon frames and forks by all factories…albeit the Trek example above is done at about 1/3 slower than usual frequency for some reason.

What do you think?
