Strengths: Reletively lightweight,handles great at any speed, high quality frame and components. Extremely stiff on large drops, will not let you down. Eats small and large bumps for lunch, then 7 ft+ drops for dinner. Takes any beating in its stride. Great trailbike, ok XC, medium DH/FR. My first non- Wal Mart bike, but i highly reccomend it to any non- XCer on a budget.
Weaknesses: No Maestro! Rear derailer hanger broke soon after purchase (factory defect?), but replaced it for $6.99. Never had a problem since. Could have come with a better fork than Manitou's Splice.
Bike Setup: Stock (Truvative cockpit, Alex DP20 rims, Hayes Sole hydros, Kenda tires).

Strengths: 05 AC- Everything! Well almost everything, shock is great, brakes better than brick wall, bang for your buck. This is my first real bike and i'm loving it.
Weaknesses: Rear f**king derailer has fallen out on me twice, without much reason (each time takes about 3 weeks to repair). Stock seat post no good if your over 80kg and ride hard. Standard tyres very standard unless you downhill 100% of the time.
Very good alrounder for your dollar. Don't do anything wild and you should be sweet; drop 10ft, go 100km/h down a down hill track eg.
Similar Products Used: My first bike, but riden mates glory (awsome 8.8" travel). Sorry just got into downhilling.
Bike Setup: Stock, apart from seat post.

Strengths: i am writing about the 2005 ac- i thought most of the spec was good. the forks are plush and i did a 6 foot drop to flat with it set on the 5.3" setting and it didn't bottom out(i am 15 and weigh 64kg)the cranks are sturdy and the bars are good. i did a 150km Polaris challenge ride on it over two days with dh tyres and the suspension set on 6.6" so it pedals relatively well.I AM SICK OF PEOPLE SAYING THIS BIKE IS BAD, IT IS EXTREMELY GOOD VALUE FOR THE PRICE.
Weaknesses: i think the sram x7 rear derailer is pretty unreliable and the tyres are too heavy unless you are doing dh, for which they are great. the bottom bracket is a bit unreliable too as are the hayes sole breaks but all these things can be fixed with a little maintanence.
its a great bike for the price if you are on alow budget and want to dabble in everything. however, i would opt for a slightly more expensive bike if you are planning on doing some enduro/xc style peddaling. cheers
Bike Setup: 8" disks 8" travel back and front. spliced front shok fox in back.

Strengths: One hell of ride and probably the most plush bike for six inches of travel. I might be thirteen but that doesn't mean I can't ride. I have done downhill, XC, and skate parks on it she still holds together. 6 footers and stairs are no problem. When landing and doing downhill this bike is like a sofa on wheels becuase of its high quality componets. I realy like the fork and the frame.
Weaknesses: Even though I love this bike I have had some problems with the rotors, derualir hanger, rear shox, rear tire poped for no good reason and it is starting to make noises like a b@2#h. This bike has pissed me of real bad when the rear shox bottomed out and stuck, I had to wait for 3 weeks to get it back. The rear tire popped beacuse it was made in France so I wasn't to happy about that. I still have the stock front Hutchison tire and it is so loud on paved roads that I can't even hear my self talk. Otherwise its a nice ride.
If you want to multitask and ride any way (even works as good road bike practice) you shuld get this bike But I warn you Do not get the new 2005 AC only get the 2003 and the 2004 models becuase they kick ass. Good luck whoever buyes this bike I highly recommend.
Bike Setup: Stock and all replacment parts except for tires are the same becuase I do not need any better.

Strengths: No bike I have ever seen or ridden is this all-round. Hucking is fun cause you can throw bike around easliy.
Weaknesses: Rear end gets a bit beat up when going FAST over rough terrain. Worry about frame over long term if hammering on all the time...
Wicked all-round bike...mind blowing actually! Ridden in 24hrs a few times...people looked at me funny...til I blew by doing downhill... Taken 8+ drops with it (good tranny's)...no problem..can't say enough about how this bike works in the whistler park...major air and fun...just make SURE tranny is good. Bang for buck...wild!!
Bike Setup: 03 dirt jumper 2 (5"), 4-way, north shore DH cranks..x.9 rear, 2.6 Kenda's on I-have-no-idea-but-they-were-built strong rims...

Strengths: manitou Swinger 4-way is the sh*t with spv volume and pressure adjust . Hayes hydro 8" rotors provide awesome stoping power. great component specs including race-face north shore dh crank, xt derailliers, and titec all 'round. the crank also comes with a chainguide and a bash guard that you can switch out. i love how the suspension is setup with the rocker bars and pro-pedal design. this is my second bike from giant. their customer servise is the best around.
Weaknesses: hutchison octipus's leak like no other, wish there was more travel in front maybe a double crown fork. dont like the clipless pedals, put some platforms on it if you ride dh or fr. brakes squeak a little.
if you get a chance to buy this bike for the price i did then do it. msrp is 3000, and it shows. the specs on this bike go on forever. cant stop talkin bout the swinger 4-way, one of the most adjustable shocks around. you may hear that the swing arm looks frail and cant withstand drops of 4-6 feet, that is not true. color is alright, too. the ac1 is one of the lightest fr/dh bikes out there. my friends dh50 comes out to bout 50 lbs while im @ 30-35.
a few words of advise, dont get the 05 ac if u can get ur hands on something like this. the 05 ac is crap compared to the other years.
every rider from cross country to downhill will love this bike. just test ride one, you'll see what i mean.
by the way, doesn't it seem like most of the people who wrote a review for this bike live in colorado?
Bike Setup: stock except race-face bash gaurd and stomp platforms

Strengths: burly frame, solid components spec.
Weaknesses: 27.2 titec seatpost
bought in early spring of 2005 from my local bike shop. wimpy 27.2 shimmed titec seatpost bent after 3 rides. having seat tube reamed for full-sized 31.8mm post. no pinhole leak problems after adding 2 units of stan's notubes. wimpy cables ruined after 1 long wet muddy epic - upgraded to fully sealed $30 flac jacket cables. great tire clearance. pedals nice in middle chainring or when seated, decent otherwise. great for technical climbs especially with z150 lockdown feature. 5.3" rear travel setting makes bike much more xc - increased springrate and damping. all in all, after a few key upgrades, this bike is solid - like the mtb version of a fresh toyote 4x4. perfect for long rides in gnarly terrain by strong riders.

Strengths: This bike has a little bit of it all. It pedals well up hills, and it drops like your mom's panties. Takes hits well, although I haven’t done anything nuclear on it. All the components have held up, haven’t had to replace anything.
Weaknesses: Paint chips like no joke. Get rid of those freaking tubeless Hutchinson. Takes a while to get all the suspension lined up. Integrated headsets aren’t sealed well, and got tons of mud/dirt in them and blew out in a short while. Kind of heavy and is a pain to pedal for long distances.
If you’re looking for a bike that’s got a bit of everything check this out. I ride it quite frequently and have no troubling complaints. I am going to turn this bike into a full free riding bike, and purchase a dedicated xc bike. It really doesn’t handle bad on the accenting terrain, but I would like something more efficient. For what I paid for it I love it. Does everything I need. Not disappointed.
All of this talk about axle to crown height and handling with different forks brought up another question. After doing some searching of the entire MTBR site I did not really find anything on tapered vs 1 1/8 steer tube strength/ stiffness.
I was set on getting a tapered steer tube fork but am b ... Read More »
