It's not an Xtracycle standard but they were protoing a heavy duty one earlier this year. Contact them for info.

Could have been a proto for the BD. Once you get to that length it doesn't come apart, so...

The point of the video was to show you it can be done under extreme conditions that you likely won't approach. I think they broke things but not big deal, it was welded back together.

It's important not to overthink things and just live sometimes.
