You could always get a stem that angles up and just flip it.

true that, but its a lot cheaper for the moment if I don't have to buy a different stem;)

That's what I did. The EA70's I got from a friend were way tall with my diabolis stem. I flipped it and fine tuned it with spacers and the height is perfect.

Two questions:

How much stantion do you have sticking out above your top crown now?

What is the total stack height of your current stem and all spacers being used?

Personally, i think it is a really bad idea, its not how the fork was intended to be installed,

So what. From a safety perspective, I see nothing wrong with it. In fact, you I bet it's stronger.
If that's what it takes to get your bars where you want them, then do it.

Personally, i think it is a really bad idea, its not how the fork was intended to be installed, you would be better off just to lower your crowns as much as possible. Even if you have alot of stantion above your top crown. Also what fork are you running? Its very possible that there is a different set of crowns made for it

I first thought the same but then now I've started to wonder why would it be so bad? I have half an inch above the crown , don't think I can go any lowers than that. As for different set I couldn't find anything for a FOX 40 that would lower the front end as much as 1/2 inch...

So, what stem are you running currently?

And what bike is this going on?

Try a Zero stack headset, and get a 0 degree stem, that should give you a solid 1/4 inch drop

Maybe throw a pic of how it looks now

As the pic above shows - it should only be done as a last resort when you have a mismatched fork/frame combination and no pride in your appearance whatsoever. :disgust1:

Oh and you'll probably have to fit a longer stem than you ought to on a long travel bike to get it to work. . . . see above.

Patineto does it and he seems to know what he's doing.

...as long as "what he's doing" is turning long-travel DH bikes into really stupid looking, excessively long travel, and inordinately heavy XC bikes.

What do you guys think about that? I'm trying to bring my front end as low as possible, Ive seen a few bikes whit this setup but I'm wondering if I would increase my chance to drop the fork or something...

I saw this on littermag and thought it was a pretty cool idea. As long as the clamping on your stanchions is all good, I cant see a problem with it.

ps - thanks Littermag!

Thats a great pic, lower the stem. and put big ass risers on. makes perfect sense. There is another thought. straight bars maybe. that will lower your front end

Metal ran his stem below the 40 upper crown to, ask him how he likes it

You could do what I did and just run a 7" fork :)

Just run a flat chromag bar,much better idea

I definitely want 8" up front, I thought about getting a flat bar but again it would be more $$$ and since.I'm about to get rid of the bike I don't think it'll be worth it... thanks for everyones advice on this, I'm still not sure if I should try it or not, it does look like **** though ;)

In the slack setting, it handles MUCH better with a 7" fork;)

What size is it and how much you selling it for?

Actually it looks like if he had the top crown below the stem he wouldn't have had enough distance between the clamps.

Medium size,I'm hoping to get 4000$ can.Ive "pushed" the DHX since Ive taken this picture..sorry for the spam.I've tried to run the fork at 7" but honestly ,it wasn't enough for what I'd want from this bike.I'm really light, smooth and I love to go as fast as I can, therefore I need the travel.

yeah to me it looks like Patineto only did that because the tubes would stick up way to high if he didnt.

The reason I mentioned it has nothing to do with travel and everything to do with bike geometry. One inch of travel in a fork isn't going to allow you to go any faster..;)

You run yours in the tall setting?

I've got some friends that are looking for bikes. I'll see if they're interested.

Lowest setting, great bike really but I just wish it was a tiny bit stepper and had a lower front end.I kept bottoming out the fork at 7", therefor I'd slow myself down, the bike isn't the problem, the rider is...

Well......maybe......

I've ridden mine in both tall and slack settings with an 8 and 7" fork.

In the tall setting, the 8" fork felt fine. But in the slack one (one of the big reasons I bought the bike), it was so slack that there was a huge bias to weight only the rear end....making it disproportionately slacker after sag. It was really difficult to weight the front end......which kind of feels like an inability to get your bars down to weight the front end in corners. Know what I mean?

You're not bottoming the fork because it's at 7 inches.....you're bottoming it because it's a fox and it takes work to get those things to ride plush and not smack bottom all the time. If you're not hitting bottom at 8 inches, it's more likely due to the fact that you're not weighting it as balanced because of how slack the bike is.

Just some thoughts......I've screwed around with mine a bunch and these are the conclusions I came to on my own setup.
