I don't know about the Team model , but the SL and Race models have really thick steel steer tubes, I mean REALLY thick. I would never expect it to break there.
I'm skeptical of the review where the guy said he broke the arch, that's what he's refering to right?
The arch on the Pike lowers is pretty damn beefy. I can't imagine it breaking there unless he managed to get a serious defect. Either that or he's a troll, who knows.
I wonder just how hollow the hollow crown is. Most of the weight savings in the team are obviously from the steer tube. Alloy steer tubes can be half the weight of aluminum ones. Even then there isn't that much weight being saved. I certainly couldn't notice the difference of .25lbs.
Marzocchi was smart to switch to Aluminum tubes for their FR forks. They are so damn reliable and require such infrequent maintenance, that people tend to forget about the rusting steel steer tube that's hidden in there. You're always guaranteed the alloy one won't rust away. Zoke's alloy tubes have LOTS of butting in the crown race area, which is good for strength (even the 66 uses it) but pretty much ensures you can't use a standard fender on it, not enough room.
Just to be safe, I would only "freeride" on the SL and Race models, unless you weigh under 150 lbs. It really has a lot to do with how light you are. I'm sure a 120lb guy could Freeride a Fox fork for ever and not snap it.
