A cool little film from Holland Cycles showing how their hand crafted ‘ExoGrid’ frames are built. From what I can tell in the video, it’s actually pretty crazy the amount of precision that must go into this.

What starts as a solid titanium tube has a distinct pattern of diamonds laser-cut out of it, which is in turn is filled by a high modulus carbon tube… It definitely looks interesting.
