Strengths:    Every thing! This bike will take a beating from any one! Yes, even from a 230lb 6ft.2in. rider doing 6 ft jumps on concrete!

Weaknesses:    So far I have only snapted the carbon seat post in half, but that was my falt, I am in the prosses to get easton to replace it.

Bottom Line:   
All I have to say about this bike is good things, I wanted a top of-the-line bike, I was ready to put down the money, I did some research, Found this bike, and I am glad I did!
I suspeck I shall have this bike for quite a long time!

Get this bike if you want a bike that will take punishment, and you WILL get al lot of attention because this bike is a beauty! Also if any should breack have some money, because this is a top bike, so you must keep top bike parts on it.

Strengths:    I seem to have a really hard time breaking it

Weaknesses:    A bit on the weighty side but I guess thats my build.

Bottom Line:   
This bike seems like it will be around for quite a while. My sons will be riding it for years after I cripple myself on it. This baby can take abuse with a smile.
A rear lockout would be a nice touch, but you cant win them all. I just crank that shock down hard and it treats me well. Floats over jumps with ease. I wish I was a stronger rider to really see what it can take, but I know I aint gonna break it!!! Its quiet, smooth, and slick.
This frame will take care of ya right, put good parts on it as not to disgrace it and ride off in to the sunset...yahoo!!
Heres how ya do it....Get this frame, mix well with good parts.....enjoy!!!!!!!!!
Ya gotta ride it to know where I be comin from...
Bottom line....This frame is the Cats Ass!!!

Bottom Line:   
I am a 260lb rider and this bike and the components I use have lasted 3 years without any problems,( I plan to switch my rims to the Spinergy xclones soon because my sin rims had finaly fall victem to warpage) I recomend this framset to anyone who is a heavy rider because this frame is bomb proof and I prove it. I have gone down some hefty trails and not one peep out of this thing, I dont plan on buying another bike ever. I already have a rebuild kit for the fork and the rear suspension. If you can find one buy it you wont regret it.

Strengths:    Stiff, Smooth, Aggressive Climber, Quiet, Tough as Nails. Looks slick too.

Weaknesses:    Not in production anymore.

Bottom Line:   
The best bike I have ever owned or ridden and I hope it never breaks. Proflex/Girven was, in my opinion, the most innovative bike company on the market. When they combined the Noleen shocks they really shored up their weak link. K2 bought them and they continued to produce some great bikes that I suspect were already on the drawing table. For whatever reason, they did not sell well and every year you could find incredible deals on last years model. My first was the 856 Proflex with the Noleen shocks. Living in Florida, I only ride CC, so this was the perfect bike. The suspension was a little stiff but it was a good transition from hard tails. I still own that bike, but wanted to upgrade and bought a 5000 because I missed out on the 957. I rode the 5000 a for a short time and liked it but was not impressed with the construction or design. The quality control was gone. I started reading about the OZ and realized that I had to have one before it was too late. I bought my frame and front carbon forks for less than $600 and built it out with all my best parts. The bike weighs less than 24 lbs and is just awesome. Everything that everyone else said before me is absolutely true. I will not need to replace this for a long, long time. I just left K2's website and can not say that I am at all impressed with anything they are offering. It all looks like the same old stuff everyone else is selling. Word of advice, "If you can find one, grab it."

Strengths:    Stiff, relatively light, looks cool, unique

Weaknesses:    no disk brake mounts.

Bottom Line:   
This is a great all around bike which could only be made better with disk brake mounts and perhaps a little more rear wheel travel. The bike climbs pretty well and desends well also. The carbon fiber frame is stiff, relatively light, and strong (much stronger than it appears). Some appear to not like the weight but I think it is just right. I recommend the crosslink fork for the XC and tight single track rider. The fork is not well suited for heavy riders (like a me) or free riding. I recently went with the marzocchi Jr. T. In my opinion you will not find a better all around fork than this. It has raised the bike a little but hasn't cut down on climbing ability. The bike also desends much better with this fork. The crosslink didn't quite have enough travel for me but it is a good fork depending on the riding style. The bike climbs pretty well for an fs bike but I would like to see another 1" in the rear. I haven't had any problems with the bike in almost a year of riding. They may be hard to find since K2 doesn't make them any more. Bottom line- this is a great bike for someone who wants to do a little of everything. As mentioned in some of the other reviews, the bike is not a downhill bike or a true XC bike, but it is good enough in all of those areas to be an excellent overall bike. Get one if you have the chance.

Strengths:    Good rear suspension, simple design to maintain. I've had two of the k2 5000 series frame and somehow this frame has a better feel to it. It feels more responsive to input, yet a smoother ride, the thermoplastic material is great.

Weaknesses:    weight, but it's still lighter than the evo frames.

Bottom Line:   
A great riding frame, the best of any proflex or K2 I've had. This thermoplastic frame just has a better feel to it than the aluminum models. I would just wish it was in the 5 pound range as opposed to 6 pounds. Other than some blown shocks a few years ago very, I've been extremely satisfied with the K2 frames. The design is very simple, easy to maintain, and totally effective. Has anyone had any luck with air shocks on the rear of these things?

Bottom Line:   
Get some a real carbon fiber frame-making process like trek had with it's OCLV y-bikes....at least there was some effort put into those things. and what is with these stupid in-house shocks??? bottom line, they blow, this bike blows, and K2 as a company blows. oh, and did I mention they also suck at making skis?

Strengths:    suspension very active.
goos stiffness, smoothness in the suspension pivots.
good overall geometry

Weaknesses:    Rides 'heavier' than expected, but not terrible.
A little more bob than I'd like.
Steering dynamics affected by rear suspension (a little more than other brands)

Bottom Line:   
Overall I'm pretty satisfied. After the Klein I wanted something a little more active...This Delivered in spades.

The pivot point could maybe use a little tweeking...a little bobbier that I'd like, but smooth out the pedal stroke and this is minimized. Doesn't climb quite as well as I'd hoped, but the DH sections and puzzles are fun.

A lockout on the rear may help

I don't really like the noleen front (from other experiences), so I opted for a judy. Personal pref though.

Cable routing OK. Use a rollamajig on this guy as the simple swingarm puts a cood bend at the Rear D.

Fun ride...I'm satisfied for the price
-good down
-not as good up
-pretty fun

Strengths:    Very tough frame, inexpensive *i got it crazy discounted @ ediscountbike.com, frame only for $500*

Weaknesses:    Noleen backshock is a lil heavy, but no worries, the rest of my components are very light

Bottom Line:   
Very nice frame, very tough although it feels like it's going to snap because it's made of carbon fiber and whenever u drop it, it makes a sound like a hollow plastic bucket :) however great bike w/ my current setup, can't wait for the snow to melt so i can get back out there. i'm looking to replace that noleen but i have to admit it has some nice travel to it, just a lil heavy due to the coil. Have fun, ride hard

Strengths:    This bike was a warranty replacement for my broken Pro~Flex 957, I made a $700 cash adjustment to upgrade from a 5000 as I wanted a bike that would last forever... this will hopefully be the last bike I ever need to buy.
I run with Marzocchi Forks and a real mix of top end parts including Formula Disc brakes front and rear. I made my own design of rear disc brake adapter, taken from my original HammerHead design from the Pro~Flex 957.
These are easy to install and can be bought online at

The bike is the best I have ever ridden. Thanks Pro~Flex.

Weaknesses:    Hard to find...

Bottom Line:   
I think I have said it already, the last bike I ever expect to buy.

I am one happy customer...... Pro~Flex finally got it right with this one.... and then axed the production..

If I had a million bucks, I'd buy a gross and give them to my buddies...

This is the perfect bike for anyone and everyone... beginners and pro's alike.

There is even a mailing list for enthusiasts... the 855heads find them at www.topica.com

I weigh 205 & 5'8", so bear this in mind, and bought just the frame. FRAME is indestructable, cannot be harmed. When I received it from the shipper & pulled it out of the crate, my first thought was "this thing is made of plastic , I will crush it in 1 day". THIS THING IS STRONG AS FREAKIN STEEL. The complete bike weighs around 26lbs, BUT Iam eyeing the NOLEEN N2 shock , and really want to toss it, BUT IT HAS NOT GIVEN ANY PROBLEMS.The bike will take anything thrown at it, I feel off a cliff and broke my rib cage, but the bike "I SWEAR TO GOD" did not even suffer a scratch LOL. The rear suspension is PLUSH, makeing my XMO feel like a rigid shock, I just wish the front felt like the rear. All in All, A GREAT PRODUCT !!!!!
