Strengths: tough, light, good geo, looks awesome (i have the the 777 version) also no one has them around here, so it turns alot of heads... also it's cheap... like dirt cheap
Weaknesses: short length... but i'm 6'4" so that's probably true for me with any DJ frame.
Bottom Line:
funnest bike i've ever owned... and defiantly my favorite. this is saying alot too because i'm mainly an XC rider. it's easy to jump, and takes a beating. just so much fun! cheap too! It's pretty versatile too. works great for street, dirt, or some light trials... it's even fun in the XC trails (though i wouldn't recommend it if that's what you're planning to do with it.

Strengths: crazy attention to detail, perfect welds, super short chainstays, spot on geometry, paint/looks ( mine is all black with white and red lettering), stiffness
Weaknesses: nothing. seriously. nothing.
Bottom Line:
i built this bike up as part of a project for school where i made a mtb movie. that said, i got to spec it with absolutely everything i want (im struggling to think of any worth while upgrades). and because of ppl i know and connections, my entire build was 1000$ ( it would have been significantly more via mail order, everything on the bike is brand new). as far as the ride goes, i can't stress enough that this bike is amazing. its infinitely more capable than i am at the dirt jump trails, its on point for street riding because of the geometry and chain stays (i can hop soo much higher than on my bro's size small kona. it really will make you a better jumper/rider. i dug a dirt quarter and learned inverts in a day! the weight of my bike isn't all that high ( the pimplites save a lot of weight) but if weight is ur concern you could throw an air fork on it and get some light weight parts. why you would do that tho is beyond me because this bike loves abuse! the only part that wasn't my first choice was the 'Zocchi DJ2, its a great fork but i wanted a white argyle 318, that would have saved a bit of weight, but the DJ2 looks better. In the end it doesnt matter though, because i cant imagine a fork that rides better, its perfect for this bike. bottom line is that this frame will go down in history as one of the most well thought out, durable, good looking and versatile (i hear ppl ride trials on this bad boy) frames ever. too bad they dont make them anymore. i'd buy my brother one if i could.
Bike Setup: 07 Marzocchi DJ2 (white), atomlab pimplite wheels on GI hubs (black with white and red lettering), simtra mcskinny bar (white), race face good n evil grips (red), maxxis 2.4 in holy roller tires, single speed, SDG f-style seat (black), titec el norte seat post,, raceface prodigy DH cranks with white E-13 bashguard, rear shimano v-brake (with white cable housing!) no front brake

Date Reviewed: January 11, 2006
Strengths: Everything. Hydroformed aluminum front triangle with square tubing rear triangle- doesn't get any stronger than that. Mine has a cool tribal paint scheme over pearl white- looks better than most guys tribal tattoos. I needed a super tough frame to do rough XC riding since I'm over 200+ and Tulsa's trails are notoriously rocky. This fit the bill perfectly and still is relatively light at 4 pounds. Built into an indestructible rider/racer at 26# with a 100mm fork.
Weaknesses: not for weight weenies.
Bottom Line:
This thing wants to fly off every rock and berm you can find and lands rock solid. Accelerates like a jet. Won't disappoint. You can find it several places on the web for 250-299.

Strengths: strong, makes u feel like u can take on anything
Weaknesses: dont be silly
Bottom Line:
I know its a jump frame and i have used it for trials but i have found it excellent for trials and i am small and only 15 and can throw it around easily so i dont care if its a pound too heavy or has long chain stays if i can throw it around any one can. Brilliant frame if you can get one get it it'd be a crime not too. Strong and looks quality and even better rides brilliantly
Favorite Trail: any town with a wall and sum rails

Strengths: strength, geometry, Cromoly, paint theme, dont see many around so the coolness factor is very high.
Weaknesses: none
Bottom Line:
This review is for the planet x bommer. I just got the new bommer in a the green and white jungle theme. Very sweet bike. It has to me one of the sickest dirt jump-dual slalom frames made. Good customer service and warranty from planet x but more than likely you wont need it since the frame is so gusseted and strong. Approved for dual crown use as well. Unfortunately I'm selling it b/c my family surprised me with a new bike. So if wanna buy an awesome frame for way less then any retail price e mail me.

Strengths: Strength, solid feel, super stable in the air, Rails corners etc! Looks awesome... Mines a Daktary on Black Glitter (rare)!!!
Weaknesses: Rear end feels long... Harder to manual. Other than that... Nothing!
Bottom Line:
I am yet to really give it a good test, as I have not had it for long! But so far so good! I have been riding mainly urban stuff lately and only a little offroad! But what I have found so far, is that it is one of the best feeling bikes I have riden for urban, jumping, bsx and all round thrashing!!!

This is a very sweet frame, and as they are not made any more almost a collectors item. The build quality is amazing and the bike rides unbelivable well, stable in the air and will take any thing you can throw at it. I also got it for less than half price.

Strengths: Everything. It's strong, sexy, reasonable weight and everything else, on top of killer geometry at a killer price.
Weaknesses: Could have better tire clearance with 24" wheels?
Bottom Line:
I like it and it. It's so full of hearty goodness that you need to try it to beleive it. So yeah, it's awesome, and that's all you need to know. Too bad they stopped making the JF Classic. A true classic.
