Um, yeah. Measured in N/degree and N/mm. So what's the problem?
A deflection has units of length
Yes, I'm confused as well. What does 79 or 67 mean? If that is the force applied to the pedal in the rig, what is the measurement of deflection? Are they measuring how much it takes to deflect it 1mm?
I would have to assume the latter. At the 45 degree angle, the force that is required to deflect it 1mm is 79.x with the Evo for example? Thus, higher/more force is required measured in N/mm to move the frame at the measurement point 1mm? I'm unclear on this.
More marketing nonsense, and then they complain about being excluded from all other competitors testing, and fail to test the Scott Foil and Specialized Venge and some others. They said on their dime they bought all of these frames. Except they didn't buy all of the frames available as a comparison. In fact, we know the Scott Foil is stiffer than the Tarmac from a few other magazine tests. Unless my memory is failing me. Which would put the Foil up near/higher in BB stiffness of the Giant.
In the Velo mag review, they put 100lbs of force on the pedal and measured in mm the amount of deflection. This I comprehend...haha..I believe a few other tests I've read use the same method.
