Strengths:    Takes the hits really well. Beefy gussets, and hayes have been working sweet. Forks have performed really well.

Weaknesses:    Creak in the headset gets a bit agitating.

Bottom Line:   
This bike has worked really well for me. I purchased it new only about 6-7 months ago (old stock in the shop). There are a few noises coming out of the headset but I can't fault it otherwise. The psylos have worked well, I have heard from other AC riders that the newer psylos tend to blow out (02-03 models) but mine are fine so far.
It is definitely the best for xc, but with some faster rolling rubber (maxxis larsen/dynomite) it does the job.

The perfect bike for those who love the downhills, but want to bike up (slowly) rather than walk.

Strengths:    this frame is strong so far. component setup is pretty good. this bike can take a lot of abuse. rockshock customer service has been great. i broke both shocks and they sent new ones w/o question.

Weaknesses:    both shocks are low quality if you ride really aggressive. i broke the fork in 3 weeks of purchase and 2 weeks ago broke rear. both need to be upgraded eventually.

Bottom Line:   
this bike is great. after i put on the vanilla rc, rear end feels much stronger. great freeride,dh rig for the price. runs great out of the box. can't wait until the '03 jr t comes out to finish shock upgrades. i have done 8 foot drops with the phylo and it has been holding up pretty good so far but to go much higher a dual crown will be much better of course. frame is strong and will hold up to abuse and seems to be durable. not a five flamin' cause of shock problem.

Strengths:    frame, parts, confidence compartment, and about every other aspect of this bike. I honestly will probably never buy another brand of bicycle as long as i ride, unless they go "mongoose". one word. tough.

Weaknesses:    after this much use, i would say that a few parts picks could be called a weakness, but honestly the only thing I would change is the lx cranks.

Bottom Line:   
if you get a deal on this bike, wait scratch that. if you enjoy jumping and trying to hurt your self or your bike, and constantly found yourself hurting your hardtails parts or your lightweight full suspension, go out and get this. this bike is bad. not just bad, but truly bad ass. i have never ridden such a fantastic execution of idealogy as this. Rolling art work. there are also travel upgrade kits available through gold-techcycles.uk, that upgrade the bike to a 5,6,7.5 inch travel bike. I am getting them, and once i do, you will be able to read about them here. 5 flaming turds.

Date Reviewed: May 20, 2002

Strengths:    Good strong bike, able to land big drops without bottoming out. Adjustable rear suspension good for XC & DH riding.

Weaknesses:    Creaking in front headseat and had rear shock lock up on first ride. Vibration coming through frame from rear disc. All repaired under warranty
Not the best XC bike out there but good compromise as really good freeride bike.


Bottom Line:   
Best bike I have owned for DH and jumps so far. Slow XC bike but still able to keep up most others and lack of speed mainly due to 2.5 tyres and choosing the Small frame size.
Very strong with relatively few breakages.
Front shocks (2002 Psylo's) are excellent, better than Z1 Marzocchi's on my 2nd bike.
Rear suspension has good action and no harsh bottoming.
Hayes 8" discs awesome stopping power.

Strengths:    This is an update to a previous review. Bike has been working awesome. I have run it with many different setups. Most recently is with a Junior T. All I can say is WOW! If you have this bike...I highly recommend putting a dual crown on it. Brings it to the next level.

Weaknesses:    Mine came with a 500lb shock and it is way too soft. Upgraded to a mountain speed 750lb.

Bottom Line:   
This is an update from a previous review. Bottom line is the bike is so much fun and can be built with many applications in mind. Put a Junior T on it and launch off anything you can find...makes the head angle perfect.

It would be really cool if Giant came out with an after market rear end like specialized did. Give us an option of like 8" of travel with a Ellsworth Dare type rear end. That would be sweet but I cant see Bigtime Giant putting in the time or effort to accomadate us like that...but who knows.

Weaknesses:    the deralliur hanger has broken 6 times already, the back shock broke and i sent it away about 2 months ago and havent gotten it back yet

Bottom Line:   
this bike would work well if it didnt brake every 2 weeks i have done 7ft drops and it lands well but a week or so later something will brake again. i do not recomend this bike to anyone because it gets expensive braking all the stuff.

Strengths:    SICK DROPS? NO PROBLEM. THE FIRST DAY I GOT THE BIKE I TOOK IT BEHIND THE GROCERY STORE AND JUMPED IT OFF OF THE CONCRETE SEMI LOADING DOC (ABOUT 5.5-6 FOOT DROP) AND WRECKED. BUT THE BIKE WAS FINE. NEXT DAY TOOK IT OFF THE SAME DROP TWICE, LANDED IT BOTH TIMES. THIS THING IS BOMB PROOF.

Weaknesses:    THE ROCK SHOX PRODUCTS I QUESTIONED, BUT INNOCENT UNTIL PROVEN GUILTY, THEY HAVEN'T FAILED ME YET. LX REAR DERAILER, BUT AN XT FRONT?

Bottom Line:   
THIS BIKE IS SICK, I COULDN'T IMAGINE TAKING THE DROPS I TAKE NOW ON THIS BIKE TWO MONTHS AGO. IF YOU READ THE MOUNTAIN BIKE MAGAZINE REVIEW OF THE AC 1, DONT BELIEVE THEM, FLEX MY ASS. THIS IS A CONFIDENCE INSPIRING DROP MONSTER WITH A MISSION OF GIVING YOU BIGGER BALLS FOR BIGGER HITS. I LOVE THIS THING

Submitted by Tony a Weekend Warrior from Corvallis, OR, USA

Date Reviewed: January 20, 2002

Strengths:    Excellent manners on the small-to-medium-sized stuff. Light(34lbs) for a bike with 6" rear/5" front travel. Jumps well. Pedals good even with the travel in the 6" position. Also pedals good while rear suspension is in motion. Adjustable compression(24 clicks)/ rebound(38 clicks) on the rear shock was a good idea anyway, even if you can't make use of the whole range. Sealed bearing rear suspension pivots are holding up well. 6-inch Hayes hydros are flawless, the only thing better would be 8-inch hayes hydros(as spec'd on the 2002 AC-1/AC-2).

Weaknesses:    I'm still questioning the rock shox products, both front and rear- when it comes to anything larger than about 3-4'(weak) drops to flat ground(if anyone at RockShox or Giant reads this, please e-mail me with suggestions)..

First, the rear shock. After reading other rider's tales of blown RS Pro Deluxe's, I was weary of running the rearshock at a high compression/rebound setting. The shock also growls at you if you actually have the compression/rebound set stiff enough. The end result: I bottomed the rear end so hard that I put a flat spot in my Rhino Lite rim THE SECOND DAY I OWNED THE BIKE. The no-name hub was also bent in the process. As a credit to rock shox, my shock has not blown yet but I really wish I could use the entire range of compression settings.

Now on to the Psylo XC fork. There's actually a combination of issues:
- external adjustability(or lack thereof), and
- initial setup was not right, probably due to poor manufacturing practices.
When I first got the bike some other guys pointed out that the fork was extremely stiff and was topping out badly, so I put a ziptie on the left stanchion to measure the sag. Even with the pre-load adjuster backed all the way out, I could not get the the proper amount of sag out of the fork. The funny thing is, when taking hits as small as 3 stairs, the ziptie reveals the harsh truth: a bottomed out "freeride" fork! Come on, RS!
Why put an external rebound adjuster on the fork with only 90 degrees (1/4 turn) of adjustment?? Even the stiffest rebound setting does not stop the shock from topping/bottoming out unreasonably.
There was also noticeable play in the front fork, but I've heard RS is replacing the bushings on 2001 psylos with the 2002-style bushing, which is 3 times thicker.

Also the chain slaps the frame a lot.


Bottom Line:   
A sweet bike, the 2002 AC-2 should be even better. If you are shyed away from the 2002 AC-1 because of the obese Marzocchi Shiver XC fork, take a good look at the AC2 because it is almost exactly the same thing. I know I wrote a novel in the "weaknesses" part, but the truth is that any beefy full-suspension bike under $2000 new is going to be compromised in some areas. When you compare the AC-2 to anything else in its $ range, I think it will emerge as the clear-cut winner. Despite the fork issues, I will still ride my AC-2 around the OSU campus pretending chicks dig it every day!

Strengths:    Great bike for extreme freeride with the upgrades I did and for downhill

Weaknesses:    none found so far

Bottom Line:   
This is my first full suspension bike ever, it rides just great. Since the moment I have it, I spent quite a few $$$ on it upgrading it to the way I wanted it to be. In future Nokian tires will be put on, MRP or FSA chainguide and SDG Big Boy saddle.

I haven't had loads of time yet to ride it, but I will do so this year and give you a later review!

Strengths:    This bike decends like it gets paid for it. Point it and its there. Can't really say enough about the bike. Buy one

Weaknesses:    Well...on my first ride I blew the rear shock out but kept on riding it! I guess the bunners at Rock Shox forgot to put it together completely. I was a little bummed but no problem. It was also hard to keep the front end on the ground for steep climbs so I am gonna change to 110mm stem...that should do the trick. I also bought the medium size and I am 6'3 so I think it will give me a better riding position. The seat sucks and the tires are so so but fatty.

Bottom Line:   
Great bike...Great price...Good bike to beat on for awhile and then upgrade when you break something. Very trailworthy right out of the box. I think that this bike would be good for anyone who wants to put their feet in the freeride waters and test it out. Not quite a downhiller but an awesome freerider. If you don't have alot of knarly terrain around you...it may be alittle to much bike but you can trailride it at the 4.5 setting.

Strengths:    Amazing, travel is very plush, handles great. love the sure wide handlebar.

Weaknesses:    Not related to the bike itself, but the brakes piss me off sometimes....make noises and rub, but I guess it's all a matter of adjustment. I used to hate the seat, but I made myself get used to it, and now it's fine, the setpost was a bit too long, but hey, I paid 2600 (CDN$) tax included, so i can live with the few pet peeves. The bike's strenghts far outweigh it's weaknesses.

Bottom Line:   
Love it! Well designed, well made, well priced (cause Giant actually manufactures their frames). I want to put on a Super T. Any word on what i should do about that? I don't care about that warrenty gerbage, I'll just put on a sigle crown if anything happens. But I just want to make sure the headtube to can take it.

Strengths:    Light, yet plush and strong. Great all round bike.The rear end seems to be very solid compared to the FSR,

Weaknesses:    Flexy in the rear if you land of center on big drops.

Bottom Line:   
I dont care about warranties so I just fitted the big forks and it takes the drops well heaps plush. The front end is high now but who cares its not a XC bike. Great rear end takes 1 minute to adjust to different travel lengths. If you want a bike that can go from DH to XC with the change of your forks this is it. I will keep it until I break it!
:)
Buy this bike if you love XC and DH cause it will do both easily even with the original Phsylo's

Date Reviewed: September 10, 2001

Strengths:    Lots of stand over clearance, travel, pretty solid.

Weaknesses:    Bottom pivot loosened after a few rides! Dual Crown voids warranty. Kinky seat post limits travel. Ahh to be able to afford a Stinky

Bottom Line:   
I actually only bought the frame. For the price the setup is pretty hard to beat. It's solid and takes some decent drops and general abuse. The Pro Deluxe seems to be holding up well so far, although I'm keeping my eye on it. It's a bit un nerving that one of the main pivots in the rear suspension loosened to nearly falling off after a few rides, if you buy one, check all this stuff! Other than that it does it's job very well. On 4 inches the back end is very solid for climbing or no bob. On 6 inches it soaks up a hell of alot! The integral headset seems good for me so far. All up I'm gonna give it 5 for value.. but 4 overall for them not doing up the rear sus and trying to kill me! ;)
