Strength:

I purchased this fork in 2005 and have been riding it very hard ever since, with the seals finally failing this past fall 2012. That's ~7 years of beating the crap out of this thing! I weigh 200 lbs. and typically ride cross-country, but I have a strong background in BMX racing, so the fork had to stand up to some fast cornering and jumps; typically through rough terrain. In the corners it tracked pleasantly with enough travel to allow you to load the shock without using all the travel, and enough rebound for us big guys to spring me out of the turn. Very stiff too.

Weakness:

It's a bit heavy, and all the adjustment knobs can be a pain to move sometimes. Wish the cantilever mounts weren't there.

A cheep fork that allows for explosive riding and very little worry about maintenance. I recommend it.

Strength:

rebound speed and lightness. Easy set up. still does a great job for the age of the fork

Weakness:

none

last year i thought about updating with a newer fork. But i after reading a lot of reviews and tips and not wanting to spend 300 plus to get something similar, i decided to keep the fork and service it with new seals and change the oil for 10wt. I even ground off the v brake mounts and resprayed the forks in white and added chrome and silver rock shox stickers to make them look a little more updated. looks really, really nice. Even though the forks don't come with a lockout i don't really have with any bob when climbing. i weigh 170 and i have the things bumped up pretty hard. The rebound of the fork is very fast and i always measure the travel at the end of a ride. i barely go beyond 70mm (my forks have 100mm) and thats jumping off anything i see. I have a pair of 2010 Tora 302 sl's on another bike and even with preload set at max, the Toras uses more travel and the rebound is much slower!!! (still a respectable fork for the money) For a fork which was designed in 2002, the duke, when set up correctly, still does an excellent job. I would still recommend you to buy a pair, especially if you are on a budget. You usually see a pair for sale for around 40

Strength:

Easy to work on. Air adjustable for weight differences. Modifying oil wt gives even more flexibility for various riders.

Weakness:

Probably not as good as some of the newer products out there but works well for me.

Like other post I have read here it needs a heavier oil for someone of my size 235. Bike was a bit soft for climbing so upgraded Float R to Float RP23 and just rebuilt the Duke XC using 15wt oil top and bottom after reading that on MTBR.COM. Great idea. Really stiffened things up and also upgraded to the Enduro seals while I had it apart. Now all the torque goes to the wheels instead of the bounce in the fork and rear shock. Had considered replacing but after digging up some manuals and using YouTube as a reference did the rebuild. Glad I did. Nice front end with 100mm travel. Works for me.

Strength:

very soft, lockout is very nice, easy to adjust, looks good, fairly cheap

Weakness:

sometimes can be too soft, alot of times only soaks up big bumps and not the smaller ones, needs oil to lockout, leaks a little air

Good fork for the price, the lockout is nice for roads or some less bumpy trails, the adjustment is easy and very easy to get to as well as filling or removing air, it looks pretty good, does not leak very much air only about 10psi per week so its not too bad, Its a very good XC fork and for the price you cannot go wrong, i would reccommend this fork

pretty lightweight. pretty good for street ^^,

Weakness:

too soft for my taste..

i bought it because i couldn't afford a pike 426, but i'm thinking about buying it next year.. but the duke is pretty good. i haven't tested the durability of it yet though :P
well, it's pretty good for streeting as i said, but when it comes to dirting it's pretty soft. i'm thinking about replacing the spring in it :P

Strength:

Durability, takes a licking and keeps on ticking

Weakness:

none so far

It's a great fork, when I ride XC in Ontario it gets me around fast and secure, I've upgraded to a carbon handlebar so I keep the fork on a medium setting and the combo fork/bar, soak everything up. Used the fork for DH/FR in BC, firmed it up with higher PSI than suggested for my weight (190) and it reacts like a charm, rarely bottoming out. Took 3 foot drops and went dirt jumping and the thing doesn't want to die, it's a great fork.

Strength:

I'm 235# and ride moderatly aggressive. Small drops, 2 ft. or less. Shock has held up fine, and seems stiff enough, while other stuff has broken.

Weakness:

hmmm, weight? Not quickly adjustable. Not many weakness IMHO,

The reason I'm writing a review is to let other big riders know that this shock is very tunable.

It was OEM on my bike, and WAY too active to climb efficiently. I'm 235#, and the front would boing WAY too much when climbing out of the saddle. Comes with 5wt oil stock. Changed it to 10wt first and really liked the effect. Went to 15wt and it is now perfect for someone my size. Compression and rebound are MUCH more controlled and the adjuster has a good range also. For fine-tuning you can adjust the oil level too. More oil = more progressive damping. Less = more linear. For final tuning I dropped the oil level about 1/4 inch, giving me slightly less activity in the first inch of travel.

To change the oil I "cheated" and just dumped the oil out of top of the fork, by removing the top cap, and pumping the shock up and down. Not the recommended method, disassembling the fork and completely flushing the oil, but my method seems to work. Also made a "dipstick" for fine tuning oil level. The fork is now "dialed in" for my size and style, and works 10X better than original. I might have already changed forks had I not taken the time to get this one working correctly.

Good fork if you fall into the designed weight range (160#'s ????) or you take the time to make it work for you!

Not gonna give it 5/5 because there may be better stuff out there for the price? But I just don't know. hThe reason I'm writing a review is to let other big riders know that this shock is very tunable.

Strength:

Stiff. Relatively plush. Cheap.

Weakness:

None really, I suppose it could be a bit lighter, but then it'd be flexy like a SID.

The best value in forks. A pity that for 05 the only Duke model in the lineup is the one with U-Turn, which adds some weight. This fork is stiffer than a Skareb, and MUCH stiffer than a SID. Which means great handling upfront. Have only serviced them twice in 2 years, and had to replace a broken spring the last time, although the fork was functioning just fine. Highly recommended!!
