What I'm judging this all on is that I've seen 888s and 66s broken in the same places. Thus I'd say both are adequately equipped to handle the task, on is obviously going to be stronger in various areas, never said it wouldn't, just feel that singlecrowns are possibly being avoided for silly reasons, urban legend, rumor, and past experiences with equipment being used beyond it's means.please everyone,put all known forks aside and just look at the facts and theories. You can't do an experiment without the same factors,we do not have any examples with the same factors so there is no statistics that or experience from current forks that really support any argument completely.
Logic and facts,keep it too logic and facts.
Lets start a list of facts.
I do not doubt that there are many 66s with trashed crowns/steerertubes, but I've got 3 videos alone saved with snapped stanchions on dual crowns, which were actually an instigator to this post... If somethings gonna go, it's gonna go, and it's only as strong as its weakest link. I just wanna know how FAR it will go before it does that!
