the bike is very nice pretty light and the fork is amazing.its perfect for pretty much anything you want to do other than hardcore downhill and freeride.

none so far

this bike is perfect for anything you want to do on it it easily handle about 5 to 6 foot drops and jumps with no problems. it has never bottomed out for me.

Decent weight, nice geometry with great standover clearance, great on climbs with platform shock, nimble in corners.

Thin paint.

This frame was actually an upgrade which I recieved from K2 after cracking a weld on my previous setup. I have been nothing but happy with this bike and have made it into my xc runner. The frame is laterally stiff and climbs well with little bob (partly in thanks to my spv shock). The weelbase is tight enough on a large frame to be very nimble in corners. Not the lightest of xc bikes, but I'm not one to count grams. An extra pound or two just means you have to be able to push harder than the other guy. At 6'2" and 160lbs I think I can spare a few grams on my bike. I can't say much for stock components since this is an upgrade, but the frame is strong with nice welds and gussetts throughout. Adjustable 4-5" rear travel is also a plus for varied tracks/trails.
K2's customer service is what sets this bike aside from others that may come in even at higher pricepoints. (World Wide Cycle Supply... K2/Ironhorse) They are knowlegable and prompt in their communication, and took care of my every need.

All in all: great bike from a great company

chain like to jump of the fromt sproket in stock form

If you have a chance to get your hands on one of these do it. the frame is strong, I weigh 238lb 6.1 and do a little bit of everything on this bike,from mild to wild, it has yet to let me down. That's not something can say about other bikes I have ridden. The derailleurs (especially the front) and brakes should be your first mod, followed shortly by the rims, stem and fork. If you like to do a little bit of everything this is the bike for you, it will climb with little to no bobbing and it will scream on the way down. It is a great platform to build your bike the way you want it.

Well, I swapped the stock fork before purchasing and I have been pleased with the suspension.

It is heavy and I've had a lot of problems with the chain getting sucked up behind the crank. I've probably gone through half a dozen chains in the 3 years I've been riding it. My current wrench suggests it might be a design flaw. Anybody heard anything about recalls.

Does anybody know if K2 has issued a recall? It's hard to have anything positive to say about a system that eats a chain nearly everytime (it seems) I need a power stroke to climb a steep.

None, this is the first full suspension I've owned. All hard tails and non suspension bikes before.

Great bike for the money, decent components, has held up fairly well.

Middle chain ring bent, not sure how. Brakes squeak, need to keep the rotors ultra clean. Make sure you zip tie the rear brake cable, or it will start to rub on the tire.

I got this bike at a year end sale, and had a 20% off coupon, so I couldn't pass this up. My previous bike was a hardtail with regular brakes, it's nice to have a full suspension and disc brakes.

As an intermediate rider, this bike has been able to take anything I've thrown at it.

I bought this bike (medium frame) after doing a lot of bargain & comparison shopping. I wanted a quality full-suspension bike, but didn't want to break the bank to get one.

Before I started looking, I didn't even know K2 made bikes... I wanted a Cannondale or maybe some other major name brand.

I was leery of buying a brand I hadn't heard of ("K2 makes skis, not bikes!", I thought), but I ultimately settled on this one because 1) It was a good deal (the price was right), 2) The bike looked cool, 3) The components and frame looked like they were put together well 4) I really liked the way it felt when I test-road it 5) Nothing else in this price range could match it on any level (IMO).

I got this bike on clearance (2005 model) from my local Supergo just before they became Performance Bikes. It retails for around $1200, and I got it for $700. Well worth every penny.

I convinced my girlfriend 2 weeks later to pick up the same bike (small frame) after I got a special coupon on the clearance item (she got hers for $600).

I'm not a stunt rider, but I ride pretty hard and fall occasionally. This bike has been able to take everything I've thrown at it. It is now muddy and scratched, but it rides well and I love it.

My girlfriend, with the same bike, feels the same way. We're both very happy with the purchase.

Please note, this is my first full-suspension bike. Although I test-road other bikes, I really don't have much to compare it with.

Still, I don't think any intermediate rider can go wrong with this bike if they're looking for a good general all-purpose mountain bike.

And when a component breaks, you always have the option of upgrading to something more expensive.

Light weight 32 lb, nice geometry, suspensions are great, it doesnt bounce at all on the way up...

None seen till now

Incredible great bike!!! just love riding it

Best Bang for your buck. Rear coilover works well both uphill & down hill with adjustment to desired give. Front suspension is adequate considering the price point. Frame is well built after the abuse it's taken. Disc brakes for a low cost bike.

Out of the gate, the breaks squeal. Front suspension could have better adjustment capabilities. Rear derailer has given me a few problems, have spent multiple hours maintaining it for proper work (maybe time to upgrade). Front of bike is a bit low for my taste (gives me lower back pain). Chain sucks up over chainstay when going to smaller chainring (same as others). Mis-shifts of front derailer caused middle chainring to bend (Performance replaced free of charge). After hard trail portion/dropdown/jumping, rear cable would catch over seat height adjuster and caused braking problems (zip tied cable to frame). Wheel brackets came apart during hard use, Performance rebuilt one and replaced the other (free of charge).

Went to my local "Supergo" store before they became "Performance" during their inventory liquidation of '05 models. I would highly recommend this approach. This is my first all suspension bike purchased, before this I had no suspension whatsoever. Went w/ the medium sized frame (I'm 5 ft 10).

Still have the squealing problem with the disc brakes, going to try some maintenance to avoid replacement. Also would need to upgrade to clip-in pedals. Not something I would expect standard in this price point.

All in all, I am very happy with the bike. It is a well-rounded unit & has performed fairly well, given the abuse I have put it through this past year & a half.

Real bottom line - I would buy it again. The price point more than makes up for the problems I have had with it. Happy hunting.

Rear shock and frame design. The moto raptor tires are excellent also, they lasted alot of miles and held up great
on rough AZ trails.

Front shock could be a little better (manitou splice elite)
but it is still holding up after several trips down national trail! The wheels that came on this bike are not strong enough
for a 6 4 240lb rider.

Nothing in this price range compare to this bike!! It rides as good as alot of $2500 bike I have ridden. Other then the weak wheels.This is a great bike for a clydesdale rider like myself
sure it is a little heavy but at my size I am more concerned with strength and this bike is strong!!

Cheap, nice sizing in the L

weight, rear shock

The fox spring is simple and effective but very heavy, at leas the 700 pounds spring is. This spring seemed too heavy for my weight, 220 pounds. I bunnyhopped off a 1 foot drop and probably got 4 inches out of the 5 inch travel. And I wouldn't want to drop anything bigger on this frame anyway. The XL size of this bike was built the 800 pounds spring, I'm 220 and I couldn't get that to move even an inch bunnyhopping. We hung the L size on the scale and it came to 34 pounds. Yup, the shop guy couldn't believe it either. On the plus side, in my demo ride the sram 7 shifters, front and rear de'rs were surpsingly smooth and fast.
