So what happens when the tire(s) unload?
Caltrac had similar design principle.
I get they are trying to free up the traditional binding issues..
Need an actual shackle on the front end.. or you just pre-load the crap out of the bar to keep it from smacking the forward stop.. and you're functionally back to the old traditional style
I looked at the video, went and found the install instructions, and noted that they have a shackle at the front, but limit its forward movement. Never got into traction bars (never made enough power) but it seems the only new thing in their offering is the bent bar for ground clearance.
