was the fork set up right

ex) correct amount of PSI and compression for what it was being used for?

Yeah, but it was a prototype or so I've heard.

Um...looks flexy....:wonky2:

Just riding along or...? That looks like Derek Chambers in the pic, who is currently racing the World Cup circuit, so I doubt its some sick hucking disaster. Seems unlikley that it would fold like that in racing conditions though. Something musta gone really wrong. Anyone have the scoop on that?

2 chaps did their forks in exactly the same way at caersws last year.

bottoming out the rear before the front hits the deck, giving super slack headangle and pop!

fork might be a proto but the lowers sure look like the same cast so thats not the issue

the issue is that stuff like that is bound to happen all the time at the WC level of racing, to a point you can say that, if it didnt, bikes would be overbuilt.
 
Sure, this is all the product of a badly setup fork. See, what really happend was that the day before a race, he got a new goodridge brake line, he found out the line was too short, and he didn't have time to get a longer line, because it was sunday, and all the shops were closed. So he decided that he would just make do by compressing his fork, and have a buddy put the brake on while he held the fork. Because he was using a goodridge line, which is uber strong it kept the fork at seven inches of travel. Half way down his race run, he hit a 1.5m drop, and topped it off so hard, that the strength of the brake line, and the fact that his brake line was routed on the front of his fork lowers (see picture) was the actual cause of his WC snapping. Or it could be the fact that the fork is just over six pounds....breakage.

that fork is 6lbs because its got no springs, cant see how a spring inside the fork uppers would have changed anything.

cant see how the grossly stupid setup you mention about the brake line could have affected anything either, actually.

the probable culprit is the fact that boxxers have, for the last few years, used paper thin sidewalls. i've seen plenty of people running guards on the slider to prevent getting holes in it from scraping on rocks, etc. i thought this was well known.

mackster23: for the record that fork is under 6 lbs.

as a long time boxxer owner.
i have to say you hit the nail right on the head.

it doesn't take much of a scrape or impact with a rock to slice or puncture right through them.
i've gone through three in the past few years from just that.
and sliced one just last week.
wasn't that big of a scrape but it laid waste to the r.s. lower and damaged the boxxcart cartridge inside.

thanks for the thread j.r.
i'm on the fence on what fork to get.
a w/c or fox.
that photo helped me decide what side of the fence to launch off of.

who said axel paths are for rear wheels? thats got a sweet rearward path, its gonna suffer from brake jack. but who uses brakes anyways...:P

if you look carefully at the brake leaver closer to the camera, you can clearly see it a goodridge line... that smokey color.

i've seen forks break like that before.

it's just like someone said previously about landing tail first.
watching guys jump d.h.bikes by pulling the front up too high and slapping the front down is hilarious.
a couple of years ago, a guy was jumping with that style and we watched him rip the headtube right off a foes d.h. frame.
forks aren't designed for that type of stress load.

i'm not saying that this was the case with this particular fork.
but seeing where it broke right at the end of where the stancion tubes would be if it was at full extention.
sure makes it look like rider error not an inherent flaw in the fork.

But dosn't the Fox fork also thin walls - with the weight you should think so?

Yeah, fox is the same. They snap at the arch. I saw three of them break in the exact same spot in less than a month. Two in the same weekend.

The moral is: It doesn't matter who makes the fork, at 6-ish pounds, you can't f#$* around.

Dammit, this is a "point and laugh" thread at a funny picture.
It was not a knock on Rock Shox or anything.
All lightweight DH race parts break here and there.
But this is a funny pic.:rofl:

Wow I count myself lucky I have never seen a fork do that.....

I wouldn't want to be the pilot when that happened. :dead:

I am amazed the rods inside the fork held onto the lower....err lower lowers. ;) I hope that doesn't happen to a fork I ride.
