Improvepart gripnut Chris King question.

From what I can tell, the 1 1/8" version is pretty much the same design as the Gripnut, 1" and 1 1/4" are your common/garden double-nut design.

Interesting company, hadn't heard of them but looks like they're remaking some pretty cool vintage parts that could be used to bling up daily-riders guilt-free :)
