I might get a 888 or Dorado, would it be okay to put on a Giant AC? Would it create problems with the bike? If you know any thing from personal experience let me know.

I'm pretty sure those would be too fork for an AC. My friend has a Marzocchi z1 (5") on his bike, and it feels perfect. I think a 6" fork would be the highest to go on it.

A 7" on an AC, would probably mean: slack, tall, too much stress on the HT.

Good job asking before you do something. Some people have done stuff, then asked.

It makes the bike ride horribly. I had a DC sherman on my AC. it wasn't nearly slack enough for any real DH. And it jacked up the BB so high it was unbelievable. I had to ride it in the 4.5 inch position to get it to feel decent and even then the BB was way over 15 inches high. A 5 inch SC such as a pike or something would feel good on an AC though.

It still would, regardless of weight. The added stiffness of a top crown transfers the force into the headtube where as a singlecrowns force is put into the steertube.

Besides that, the geometry would probably be screwed up.

NO. Can you not read? I just explained how crapyp the bike becomes with a tall fork and now you still want a tall fork? So basically you made a thread so you could just not listen to anything negative that people tell you. Genius really.

I just don't want to break off my HT. I dont really mind how tall it will be. A 66 has 6" of travel. only an inch more than what I have now.

Some of the newer AC's can handle a DC fork since the last year they made them they had a Sherman DC on it. Again you don't want to get a taller fork or you will mess up your geo..

You can also get it in 150mm.
The 05 150mm 66 is probably at least as tall if not taller than a 7 inch 06 66. Both are far too tall. They will jack the BB up and still put excess stress on the headtube (even though the AC is dual crown approved according to giant). Basically if you want a 16.5 inch BB be my guest. I can tell you that for FR/DH the AC rides like ****. It's a trail bike and nothing special at that.

Still that slider was only 6 inches. And they are very short forks. So it has the A-C measurement of the average 5 inch fork.

The '05 66's were huge. A while ago, someone on here put a 7" one on a V10 and the head angle look right. :eek: I'm pretty sure the '95 6" ones are taller than the "06 7" 66's.

Is it true that there are no 6" 66's for '06? So, you can't move the spacer and make it 6"?

A seven inch Dorito is a short fork, probably as short as a 6 inch 66. It would look really funky on an AC though...

This begs the question, why are you considering putting a DH fork on an AC? ACs are XC/Trail bikes with more travel and craptastic geometry...why not sell the AC frame and buy something more suited to what it looks like you want to do? People sell DH frames in the B&S for cheap...like, under $500 cheap. I think I saw an SGS frame for $350. Just a suggestion.

one thing you want to do before you go and do something as drastic as putting a dc on an ac. you need to check your warrenty info. they should have something about how much travel you can run on the frame or if you can run a dc or not. although with this said i think 5" should be fine. if you want to run a dc or more travel man and do big hucks with it or start racing on it just get a different bike man. just one mans opinion.

Stick with a 5" SC fork, any bigger and you'll push the bike past its limits. Blah blah, it's warrantied for DC and all that crap, but the AC is a glorified trail bike with terrible geometry and a tendancy to crack. Find something better to ride if you want to go faster/bigger/harder than you do now.

I want to put a DH fork on it because I like DH/FR. And I'm really light, so I'm not worried about stress on the HT. Also, I like the way the bike feels.(geo wise) And last, I will get used to how much taller it will feel.

Have you ever ridden on a bike that had a fork to tall for it? I feels...rather unpleasant. The steering goes into what I like to call "flip-flop" mode. Your front end just kinda flaps to either side. Also, your weight will matter little when you are landing jumps. It is magnified by many times when you land. Being a fatass would only make it happen faster, being light will simply help keep the disaster at bay.

BUT, since you only want to hear, "GO FOR IT DUDE!!1!" Im going to go ahead and say try it. Gotta' learn somehow.

I think you missed my point-

The AC is not a DH/FR frame, so you shouldn't put a DH/FR fork on it. Buy a more suitable frame.

My buddy has a Stratos 6" on an real old AC and I think it feel terrible..... flip flop. He loves it though. One of these days the HT is going to SNAP.

Basicly it will be like a chopper - slack and tall, then the headtube will fall off sooner or later. My friend has one with a Marzocchi z1 (130mm). It feels perfect on the bike.

Yeah, I have a 5" fork right now. But its a crappy Manitou. And I want more travel because I'm starting to hit bigger stuff. Would a Travis 150 raise up the front end a ton?

Many times, quality over quantity in travel can be better. I think you should get a marzocchi z130 or z150. People hit big stuff on bikes with as little as 5", or less. Some people even hit stuff huge Freeride hits on hardtails.

I think 5" would be good. If you find the one with ETA, it will be smoother (hscv as opposed to ssv).
