Strengths:    Everything: this bike was WAY ahead of its time.
Frame Geometry
Rear Travel
Chain Guide Brackets
Cable Routing
Strength to Weight ratio


Weaknesses:    Stock Fork was 130mm.
This bike is MUCH better with a 140 & perfectly balanced with a 150mm


Bottom Line:   
Best aggressive XC/AM frame for several years.
This frame was WAY ahead of its time. The current Yeti 575, Trek Remedy, Intense Tracer 2, and Specialized Stumpjumper all take cues from this frame and mirror what the AC had 7 years earlier.
Mine was completely stock with the cool rear shock and Manitou 130mm fork.
It performed amazingly and the value was insanely good.
Over 2 years of playing with different set-ups I tried a bunch of configurations.
I did a 1x9 Freeride setup with chain guide, short FR stem, piggy-back coil rear shock and a heavy 145mm fork, the bike was a blast.
I did a 2x9 XC setup with a Fox Float RP2 rear shock, bike was great.
But the best setup is the one I currently have:
Full Shimano XT shifters, XT derailleurs, XT crankset 2x9 w bash ring, XT hydraulic brakes
Fox Float 32 150mm fork w Thru Axel
Fox Float RP23 rear shock
Shimano 31.8 Carbon Pro riser bars
Thomson Elite 90mm Stem
Thompson Elite Seatpost & Seatpost Clamp
Mavic Crossmark wheels
Maxxis 2.35 Highroller rear
Maxxis 2.4 Ardent front

My current setup is amazing and I would advise anyone with an AC or looking to get one to try this configuration.
I also loved running the same setup with a Manitou 145mm thru axel fork paired with a Manitou Swinger 4 Way air shock.
I swapped the Manitou parts to another bike and shaved anothe lb off the weight of my AC when I went to the Fox setup.
Only bike that keeps up with my AC is my tricked out Trek Remedy.
LOVE the AC!

Strengths:    Seriously strong, plush, neutrally balanced, and great in corners.

Weaknesses:    For an XC bike its probably a little on the heavy size.

Bottom Line:   
Ive just finished building this bike - using it for a bit of XC, but its fast becoming a downhill bike. I love riding it on quick flowing downhill sections of trail with medium jumps. It lands plush and strong on the jumps, and you can dig it hard into corners, and it just never gets out of shape. With the long front forks on the front, its great on drops as it has a good steep head angle.

Strengths:    Indestructible, lots of travel, nice on downhill slopes and the brakes have good stopping power.

Weaknesses:    Psylo shocks pisses oil, rock shox rear is too bobby. Also its a bit heavy.

Bottom Line:   
I've ridden this bike for years (model year 2000)and nearly killed myself a bunch of times but you just can't break the frame.
Each time something breaks I just upgrade it so now it's totally tricked except the Hayes breaks (still stock) and the rims. The bob is gone in the back with the Fox DHX5.0 coil and it rides like a totally different animal (now it climbs well and does not bob because of the pro pedal).

The stock bike with Psylo's needs a different shock and the Rock Shox Deluxe just bobs too much.
I love this bike but this is not a XC ride. It kills at crushing logs and taking abuse.

I loved the Stumpjumper with the brain and the Element 50 was sweet. The GT with iDrive stock kicks the Giant. The Stink was no match for the AC2


Bike Setup:   I replaced the stock front shock after it bled to death with a Marzocchi Junior T and the rear Rock Shox with a Fox DHX 5.0 coil

Strengths:    Versatile, all arounder-do it all

Weaknesses:    Seat tube, bottom bracket constantly creaks

Bottom Line:   
Ya, a little old school, climbs & pedals well in the 5 1/2" rear travel mode--too much bob & squishy ride in the 6 1/2" rear travel mode-but very plush. Climbs lousy in 6 1/2" mode. Neutral handling--no glaring faults. Seat tube seems to be the greatest weakness. Cranks almost always creak, but goes away with serving--maybe a Shimano set up would be better.I jump very little in quality & quantity, so being old school myself--I need to keep the rubber side down! I'm not sure I would trust it on medium to big air...its just a good competent all around bike-nothing out standing, but no glaring faults either. Works well at North Star, Tahoe, Skeggs, Boggs, Soquel, UCSC,etc--it does what I want to and that's all that matters---now if I can only get a new 2009 Intense VPP Tracer! It looks very appealing.

Strengths:    Good bike for the price, it did very well on descents.

Weaknesses:    A lot of bob, even when adjusted for less travel.

Bottom Line:   
I used to do a lot of to hikes the tops of mountains, and then shooting down. I also do some cross-country riding. This was my first FS bike. It worked well for the mild DH riding I did, but I was surprised by how much power was absorbed by the rear shock. Lately, I’ve lost interest in downhill riding in favor of long XC rides, and I found the bike so cumbersome on the trails I like, that it was mostly just collecting dust while I took my old hardtail out on the trails. I’m now riding a XC designed FS bike that works much better for me. Overall, I think it was great when I used it for what it is designed (light freeride/downhill). It was not, however, the do-everything bike that I was hoping for. Overall, I’d say this is a perfect bike for a not so hardcore downhill rider, but if you do a little of everything, I’d go with something else.

Date Reviewed: August 27, 2007

Strengths:    2005 AC
Hayes Hydro stop quick
WTB Laser V seat is good
Carbon seatpost & bars are nice addition
Not too heavy (my medium is about 35lbs with heavier pedals, grips and a different rear spring.


Weaknesses:    Stock shock is sprung for a light rider with a 500lb spring - but you can get a new spring 800lb for less than $30 from Giant and this helps so much for heavier riders. With the 800lb spring the bike no longer acts like a pogo stick. I used to hate to take it on the street for more than 5 minutes because of pedal Bob. 800lb spring changes the shock and supports my 200lb frame.

Front Fork - lockout would have been nice, but they had to keep the price down at this point.


Bottom Line:   
Great value in an all-mountain full suspension bike. For 2005 they put on mid level components and cut the price in half! I wish they still had this in their lineup (or something similar at around 1k)

Strengths:    reasonable travel, geo, ect

Weaknesses:    clicking noises, flex, frame strength concerns, annoying integrated headset.

Bottom Line:   
its a decent beginner frame, the two shock positions make climbing a little better, but issues with frame strength make me a little apprehensive.

overall, a great bike to learn on, and a good all rounder, but not something to hammer on dh trails all day, every day

Strengths:    the good thing about this bike is its cheap as anything and has soft suspension with good parts.

Weaknesses:    the suspension may be soft, but damn! i've bottomed it out at about 30cm, also i have a continuing problem wich i blame on giant for making the dropout out of aluminium! i've been through 5 in 4 months!

Bottom Line:   
well, although this bike breaks easily, has suspension thats to soft, and needs constant maintanance, i wouldnt go to anything else! and thats not just because i'm broke, as soon as i get it fixed and get new gear parts and a new rear spring it will be the best bike, it has awsome geometry and handles like a dream! i wouldnt want anything else for my level of riding, if your a beginer, this is where you should start!

Strengths:    great suspention, Nice wide kenda tires that don't wear easily, good strong breaks, handles nice on down hills, can handle almost anything, takes jumps and drops like a champ, awesome free rider, it can do cross country riding too. and it looks hot

Weaknesses:    grips wear out FAST, chain rings have large rivets that catch the chain and jam it up when you shift into a certain gear. slow on the up hills

Bottom Line:   
heavy but good all around bike for free riding and some downhill. GET NEW CHAIN RINGS! if your looking to just ride cross country turain go with something lighter but if you want a bike you can push this is a good one.
